Abstract
Aspidistra laongamensis C. R. Lin & X. Y. Huang, a new species of the Asparagaceae from Saravan Region, Laos, is described and illustrated. The new species is similar to A. lubae Aver. et Tillich in the perianth shape, but differs by the creeping rhizome, externally yellowish white perianths with internall yellow lobes, and the flat, glabrous stigma.The new species is also similar to A. nankunshanensis Yan Liu & C. R. Lin in the ovate-triangular, internally yellow perianth lobes, but differs by its urceolate perianth with an internally purplish red tube, and stamens inserted in the middle of the perianth tube, and mushroom-shaped pistil. Aspidistra laongamensis is currently known only from Laongam city, southern Laos.

Abstract
A new species of potamid crab of the genus Teretamon Yeo & Ng, 2007, is described from Namdapha Tiger Reserve in Changlang district of Arunachal Pradesh, India. The new species, Teretamon kempi n. sp., can be distinguished from its congeners by a distinct combination of carapace and gonopod characters: a relatively high carapace with a bilobed frontal margin; subquadrate sixth abdominal somite with nearly parallel lateral margins; and a relatively small G1 terminal segment with a semicircular to bluntly triangular dorsal flap. All known Teretamon species are compared with the new species, and a key for this genus is provided.

 Isophya horon Sevgili, 2018


Abstract
A new interesting species of the genus Isophya, Isophya horon sp. n., is described from Northeastern part of Turkey. The new species can clearly be distinguished from the closely related species by the calling song of male, and morphology. Morphologically, the shapes of the pronotum, tegmina, male cerci and ovipositor are distrinctive. The morphology, song structure and distribution clearly indicate that this new species is a member of the I. zernovi species-group. Additionally, some preliminary data on the male calling songs of closely related species (I. zernovi, I. karadenizensis and I. autumnalis) are also given. In addition, the preliminary data related to spermatophore characteristics (spermatophylax and ampulla weights) and sperm number of the new species are provided.

 Stemodia lanceolata Benth.

in Scatigna, Mercedes Sosa, Souza & Simões, 2018. 

Abstract
In this contribution, we reassess the identity of Stemodia lanceolata (Plantaginaceae) and confirm its occurrence in Brazilian territory. We present a detailed and updated description, a fine illustration, and photographs of this species, along with comments on its distribution, habitat and phenology, and notes on taxonomic affinities. Stemodia lanceolata is characterized by its stiffy erect terminal inflorescence with filamentous aspect due to the long, linear-triangular, frequently out-curved floral bracts. Finally, we propose second-step lectotypifications for three names subordinated to S. lanceolata.

Australobius tracheoperspicuus 
 Li, Pei, Guo, Ma & Chen, 2018


Abstract
Australobius tracheoperspicuus sp. n. (Lithobiomorpha: Lithobiidae) was recently discovered from the Cave of the brickyard of Gaofeng village, in the Guizhou Province, southwest China, and it is described here. Morphologically the new species is similar to A. magnus (Trozina>, 1894) from north-western China. The new species can be easily distinguished from those by the trachea connected to the valve of the TIII clearly visible from the dorsal side, the absence of ocelli on each side of the cephalic plate, the DaC spine being only present on the XIIIth–XVth legs. Numbers of examined specimens, distribution and the main morphological characters and an identification key to the known Chinese species of genus Australobius based on adult specimens is given.

Abstract
A new species of grouper, Epinephelus craigi sp. nov., from the South China Sea is described from 17 specimens (104–250 mm SL). The new species is distinguished from Epinephelus stictus (Randall and Allen 1987) with which it has historically been conflated, based on coloration, meristics, morphology, and genetics. Epinephelus craigi sp. nov. has a unique color pattern of irregular squarish, dark brown blotches interrupting lighter brown bars along the lateral midline of the body, and small dots on the dorsal surface of the body. Additionally, E. craigi sp. nov. has a longer upper jaw, shorter snout length, narrower interorbital width, and shorter caudal peduncle than E. stictus. Both E. stictus and the new species are relatively deep-water species, with the new species occurring to at least 93 m. Epinephelus craigi sp. nov. is known from the South China Sea and E. stictus is known from Western Australia and southern Indonesia, suggesting allopatric and anti-equatorial distributions. DNA sequence divergence data of the mitochondrial COI gene further supports the distinction of E. craigi sp. nov. from E. stictus.

Abstract
Henckelia pathakii G. Krishna & Lakshmin. sp. nov., is described and illustrated here from Upper Siang district of Arunachal Pradesh, India. It differs from its closely related species H. adenocalyx and H. grandifolia in having cupular bracts (vs. free and slightly connate at base) and glabrous (vs. densely hairy or sparsely pubescent), eglandular calyx. As it is narrowly confined to Upper Siang district of Arunachal Pradesh in a small population comprising about 20 individuals in a single location. The threat status of this new species is provisionally assessed here as “Critically Endangered” following the IUCN Red List Categories and Criteria version 3.1 (2012).

Abstract
Lebbiea grandiflora (Podostemaceae), a rheophytic herb from the Sewa River rapids in Sierra Leone, is described as a new species. It is the first new African genus of Podostemaceae published for 30 years. First collected in May 2017, the species is assessed as Critically Endangered using the IUCN 2012 standard. It is on the edge of extinction with a small population at a single site threatened by deposition of gravel and sand from alluvial gold and diamond mining upstream, and a planned hydro-electric dam. The new genus is unique in Podostemaceae in a) its highly developed and robust style-stigma structure in which the bases of the two style-stigmas unite to form a bifurcate funneliform-cylindrical structure, with a reflexed, blade-like apex that extends half-way around the perimeter of the ovary-fruit towards the base of the ovary-fruit, b) a specialised andropodium, with robust, self-supporting capacity, having differentiated thickened central, and angled, thinner marginal areas (in other Podostemaceae the andropodial structures are undifferentiated), c) the pillar-like haptera which completely elevate the crustose root above the substrate. Lebbiea is placed in Podostemoideae, necessitating amplification of the delimitation of that subfamily in which it is additionally unique in having the foliose tepals characteristic of the basal subfamilies Weddellinoideae and Tristichoideae.

Lebbiea Cheek gen. nov.

Type: Lebbiea grandiflora Cheek sp.nov.

Diagnosis: differing from all other Podostemaceae in the basally connate style-stigma pair which form a short, bifurcate, funneliform cylinder, the apices of each style-stigma reflexed, forming a keel which encircles the distal perimeter of the ovary (in all other species the stigmas are not divided into basal and distal parts, and if conjoined never form a cylinder, nor have a keel-like distal part); also differing from all other Podostemaceae in the robust, free-standing, concave andropodium, differentiated into thinner marginal and thickened central portions (not depending on hydrostatic pressure to stay erect, not flat or cylindric, undifferentiated); differing from all other Podostemoideae in the ovate, concave, tepals that conceal the ovary (not filiform, inconspicuous) (Fig 1)


Lebbiea grandiflora Cheek sp. nov. [urn:lsid:ipni.org: 77188051-1]

Type: Sierra Leone, Sewa River, between Fomaya (Kenema District) and Ngnawama (Kono District), 257 m alt., fr. 5 May 2017, Lebbie A2721 (holotype K! K000875049; isotypes SL!, US!, ZT!)

Etymology: The generic name Lebbiea commemorates Dr. Aiah Lebbie, Head of The National Herbarium of Sierra Leone, Njala University, Sierra Leone who collected the type and only known material of this genus. The specific epithet refers to the flowers which are the largest known in the family in Africa (4-5 mm long above the pedicel), exceeding even those of Dicraeanthus africanus Engl. (3.5 mm long above the pedicel).

The Koukoutamba falls in Guinea on the Bafing River of Guinea-Conakry.
With 5 species of Podostemaceae, three globally threatened including two new to science (one of which is Lebbiea), it is the richest site known for Podostem species diversity in Guinea.

Distribution: Known only from one site on the Sewa River in the Kono and Kenema districts of Eastern Sierra Leone. The nearest settlement is Nɡnawama, several kilometres drive from Jaiama Sewafe, a large settlement dependent on alluvial diamond mining (Fig 2).

Ecology: Lebbiea grandiflora grows on submerged rocks in river beds, in the wet season, where they have been found in the middle of the river and close to the river bank. At the height of the dry season when falling water levels have exposed the rocks, the plants flower and fruit and die off (they can be easily scraped off the rock at this time). They grow in small isolated patches on rocks, covering the horizontal surfaces in a mat-like appearance with the flattened roots. Two of the observed clumps were growing on rocks in the middle of the river, with the third one close to the edge of the bank where a small rapid was still observable at the height of the dry season. The mass of rock on which it was growing had been partly dissected by the erosive forces of the river current, developing numerous small basins in which water was still present, sand and pebbles from the alluvial diamond mining had also settled. In the cracks in the bedrock and at the edges of the numerous basins can be found tufted water grasses growing in association with hydrophytes such as Hygrophila spp. (Acanthaceae). These plants probably serve to modulate the water current over the rocks in the wet season. Pterocarpus santalinoides L'Hér. ex DC. (Leguminosae-Papilionoideae) was the only tree growing on these rocks in the middle of the river.

Abstract
Two praying mantis specimens were collected on the island of Hiva Oa of the Marquesas Archipelago, an isolated island chain located approximately in the centre of the Pacific Ocean. While external morphological features agree with the diagnosis of the genus Tropidomantis, the unique combination of character states reveals that they represent a new species. Furthermore, this is the first record of a praying mantis collected in the Marquesas Archipelago. We describe the morphology of the species, illustrated by high resolution habitus images, figures of diagnostic features and measurement data for Tropidomantis kawaharai sp. nov.

Abstract
A new genus of bee fly (Bombyliinae: Bombyliini) is described to place a unique species Paramonovius nightking gen. et sp. nov. The new species is only collected in winter and is only known from a restricted area in Western Australia. Our morphological phylogeny indicates the new genus is sister to Sisyromyia White, 1916 and is similar to the latter in some external characters such as the one‐segmented antennal flagellum with apical stylus, subapex with 3–5 long hairs, open cell r5 and cell br nearly as long as cell bm. However, Paramonovius gen. nov. has dichoptic male eyes, sparse scales on the median abdominal stripe, enlarged claw and pulvillus, as well as a series of autapomorphies in the genitalia. We present a modified key to the Australian genera of Bombyliini to accommodate this new genus. The unusual flight time of this genus may have contributed to its rarity in collections.

Genus Paramonovius gen. nov.

Etymology: This generic name is in honour of Dr. Sergei Jacques Paramonov for his significant contribution to Australian dipterology.


Paramonovius nightking sp. nov. 

Etymology: This species is named after the Night King in the American fantasy drama Game of Thrones, because all the specimens were collected in winter and the fly is mostly covered in thick pale pruinescence. The specific name is treated as a noun in apposition.

Abstract
Bulbophyllum chrysolabium, a new species belonging to section Racemosae from Yunnan, China is described and illustrated. The species is related to B. orientale and B. morphologorum, but differs by having the following set of characters: obliquely broadly-based triangular petals with a long filiform apex; lip densely glandular papillose and conspicuously ciliolate along margins; lip auricles well developed, narrowly falcate, tapering to a long sharp point at the apex; stelidia subulate and twisted inwards, slightly exceeding operculum. The conservation status of B. chrysolabium is assessed and taxonomic notes are provided.

Bulbophyllum chrysolabium L. Li & D.P. Ye, sp. nov.

 Diagnosis: Bulbophyllum chrysolabium is distinguished from all known congeners by having the following unique combination of features: obliquely broadly-based triangular petals with a long filiform apex; lip densely glandular papillose on both sides and conspicuously ciliolate along margins; lip auricles well developed, narrowly falcate, tapering to a long sharp point at the apex; stelidia subulate and twisted inwards, slightly exceeding operculum.

Taxonomic notes: Bulbophyllum chrysolabium appears to be related to B. orientale Seidenf. (Seidenfaden 1979: 138), especially in narrowly falcate lip auricles and twisted stelidia, but differs in distinctly longer floral bracts (almost twice as long as the pedicel and ovary); petals with long filiform apices, a rather smaller lip (ca. 2.8 mm long), significantly glandular-papillose and ciliolate at margins; stelidia slightly exceeding operculum and distinctly longer than column. With respect to filiform petals, B. chrysolabium is also superficially similar to B. morphologorum Kräenzl. (1908: 89), however, the latter have a fat, conical protuberance or callus on the front of the column near its base and scape much longer than rachis. In addition, it has subulate, not twisted stelidia, considerably longer than operculum; lip auricles not falcate, but rather obtuse at the apex. A detailed morphological comparison between B. chrysolabium and its allied species is presented in Table 1.

Distribution and habitat: So far known only from Menglian County in southwest Yunnan Province, China, growing as an epiphyte amongst mosses on the tree trunk near the edge of river in rather exposed circumstances in subtropical evergreen broad-leaved forest.

Etymology: The specific epithet comes from the Ancient Greek word chryso-golden” and the Latin derived labium labellum”, referring to the golden-yellow lip of the type.

Abstract
The most complete known North American enantiornithine was collected in 1992 but never formally described. The so-called “Kaiparowits avisaurid” remains one of the most exceptional Late Cretaceous enantiornithine fossils. We recognize this specimen as a new taxon, Mirarce eatoni (gen. et sp. nov.), and provide a complete anatomical description. We maintain that the specimen is referable to the Avisauridae, a clade previously only known in North America from isolated tarsometatarsi. Information from this specimen helps to clarify evolutionary trends within the Enantiornithes. Its large body size supports previously observed trends toward larger body mass in the Late Cretaceous. However, trends toward increased fusion of compound elements across the clade as a whole are weak compared to the Ornithuromorpha. The new specimen reveals for the first time the presence of remige papillae in the enantiornithines, indicating this feature was evolved in parallel to dromaeosaurids and derived ornithuromorphs. Although morphology of the pygostyle and (to a lesser degree) the coracoid and manus appear to remain fairly static during the 65 million years plus of enantiornithine evolution, by the end of the Mesozoic at least some enantiornithine birds had evolved several features convergent with the Neornithes including a deeply keeled sternum, a narrow furcula with a short hypocleidium, and ulnar quill knobs—all features that indicate refinement of the flight apparatus and increased aerial abilities. We conduct the first cladistic analysis to include all purported avisuarid enantiornithines, recovering an Avisauridae consisting of a dichotomy between North and South American taxa. Based on morphological observations and supported by cladistic analysis, we demonstrate Avisaurus to be paraphyletic and erect a new genus for “A. gloriae,” Gettyia gen. nov.

Abstract
Didymocarpus middletonii Souvann., Soulad. & Tagane, a new species of Gesneriaceae from Nam Kading National Protected Area, is described and illustrated. The new species is morphologically similar to Didymocarpus brevicalyx, D. formosus and D. puhoatensis but distinguished from the three by its fewer-flowered inflorescence, longer pedicel, and urceolate and multicellular eglandular hairy calyx. Based on the latest IUCN criteria, Didymocarpus middletonii is proposed to be Critically Endangered (CR). Our record of Didymocarpus represents a new genus record for the flora of Laos.

Abstract
Molecular phylogenetic studies of the six currently accepted species in the genus Echinocactus have partially clarified certain aspects of its phylogeny. Most of the studies lack a complete sampling of Echinocactus and are based only in one source of data. Phylogenetic uncertainties in Echinocactus, such as the recognition of Homalocephala as a different genus from Echinocactus, the exclusion of E. grusonii or the affinities of E. polycephalus, are here resolved. Phylogenetic relationships of Echinocactus were reconstructed with a maximum parsimony, a maximum likelihood and a Bayesian approach including 42 morphological characters, four chloroplast markers (atpB-rbcL, trnH-psbA, trnL-trnF and trnK/matK) and two nuclear genes. The utility of these two nuclear regions related to the betalain cycles (DODA and 5GT) are explored and discussed in relation to their potential as phylogenetic markers. Concatenated analyses with morphological and molecular data sets, plus 13 indels (2847 characters and 26 taxa), show general agreement with previous independent phylogenetic proposals but with strong support in order to propose the recognition of a reduced Echinocactus and the recognition of Homalocephala at the generic level. These results recovered a polyphyletic Echinocactus as currently defined. The here-named HEA clade, recovers the species of Homalocephala, Echinocacuts and Astrophytum as a monophyletic group with strong internal support. The Homalocephala (H. texensis, H. parryi and H. polycephala), was recovered as sister to the Echinocactus clade (E. platyacanthus and E. horizonthalonius), plus the Astrophytum clade. Consequently, we propose here to recognise a monophyletic Echinocactus and a monophyletic Homalocephala as two distinct genera with their own molecular and morphological synapomorphies. The evolution of some morphological characters supporting these clades are discussed, the necessary new taxonomic combinations for Homalocephala are proposed and an identification key for the genera, the species and the subspecies of the HEA clade are presented.

Keywords: Cactaceae, HEA clade, morphological character evolution, North American Deserts

Conclusions: 
This is the first phylogenetic study that has evaluated and combined molecular data from chloroplast and nuclear genomes with morphology to test the monophyly of all species and subspecies of Echinocactus currently accepted. Here we reinforce the proposal of excluding Echinocactus grusonii from the genus. Nevertheless, the recognition of Kroenleinia grusonii must be deeply evaluated since phylogenetic relationships of the Ferocactus clade (including K. grusonii, Leuchtenbergia, Stenocactus, Thelocactus and Glandulicactus) are still unresolved. The well-known HEA clade was recovered as monophyletic with strong support. This clade is morphologically and molecularly well defined, suggesting its taxonomic recognition. Our results also support the proposal that Echinocactus, as currently accepted (excluding K. grusonii), should be considered as two independent lineages, the Homalocephala and the Echinocactus clades, each one with its own molecular and morphological diagnostic characters, and each one representing different genera. In this study, all of the analyses recovered E. polycephalus within the Homalocephala clade, supporting its inclusion in this taxon. Here we present the new taxonomic combinations for the species of Homalocephala and an identification key for the genera of the HEA clade and for all of their species and subspecies.

Keywords: Flora, Laos, Myrtales, new species, Thailand, taxonomy, Vietnam, Eudicots


Syzygium honbaense Tagane, V.S.Dang & Yahara, sp. nov.
TYPE:— VIETNAM. Khanh Hoa Province, Mt. Hon Ba, ...

Syzygium honbaense is distinct from all the other Syzygium species in the region by having terminal inflorescences with 3 to 5 reddish flowers, ca. 1.1 cm long hypanthium and relatively smaller leaves, to 7.2 × 2.7 cm

Distribution:—Vietnam (so far only known from the type locality, Mt. Hon Ba). 
Habitat and Ecology:—Hill evergreen forest, at ca. 1200 m elevation. 

 Etymology:— The new species is named after the type locality, Hon Ba Nature Reserve in Khanh Hoa Province of Vietnam.
 Vernacular name:— Trâm hòn bà.

Note:— Among the Syzygium species having relatively large (hypanthium > 1 cm in diam.) and reddish to purplish flowers in Indochina, S. honbaense is easily distinguished from the other species by a combination of its smallest leaves ((1.7–)2.6–7.2 cm long vs. longer than (6–)12 cm) and terminal inflorescences. 


Syzygium phamhoangii Tagane, V.S.Dang & Yahara, sp. nov. 
TYPE:—VIETNAM. Khanh Hoa Province, Mt. Hon Ba, ...

Syzygium phamhoangii is similar to Syzygium balsameum (Wight 1841: 16) Walpers (1843: 179) in the shape of leaves and axillary inflorescences but distinguished by its obtuse to slightly cordate leaf base (vs. cuneate to long attenuate), shorter petioles ((1–)2–4 mm long vs. 4–15 mm long), larger hypanthium (3.5–4 mm long vs. 2.5–3.5 mm long) and more ovules per locule in ovary (12–16 ovules vs. 3–8 ovules).

Distribution:—Vietnam (so far only known from the type locality, Mt. Hon Ba). 
Habitat and Ecology:—Hill evergreen forest, at ca. 920 m elevation. 

 Etymology:— The specific epithet is chosen in honor of the excellent Vietnamese botanist Prof. Dr. Phạm Hoàng Hộ, who significantly contributed to the study of the flora of Vietnam. 
Vernacular name:— Trâm phạm hoàng hộ.


Syzygium yersinii Tagane, V.S.Dang & Yahara, sp. nov. 
TYPE:— VIETNAM. Khanh Hoa Province, Mt. Hon Ba, ...

Syzygium yersinii is similar to S. chantaranothaianum Soh & Parnell (2012: 558) in ovate-oblong leaf shape, very short petioles and terminal inflorescences but differs in having larger and thicker leaves (thickly coriaceous in S. yersinii vs. subcoriaceous in S. chantaranothaianum), reticulate tertiary vein (vs. scalariform) and larger flowers (hypanthium 1.8 cm long vs. 0.8–1 cm long).

Distribution:— Vietnam (so far only known from the type locality, Mt. Hon Ba). 
Habitat and Ecology:— Hill evergreen forest, at 890–920 m elevation. 

 Etymology:— This species is named after Dr. Alexandre Emile Jean Yersin (1863–1943), a Swiss-French, for his contributions to the exploration of the Hon Ba mountain. 
 Vernacular name:—Trâm yersin.

Note:— Lee et al. (2014: 398) identified this species as Syzygium formosum (Wallich 1831: 108) Mason (1851: 554) but S. yersinii is easily distinguished from S. formosum by its opposite leaves (vs. usually whorled in S. formosum) and terminal inflorescences (vs. in the axils of fallen leaves). The leaf texture and venation when dry is very similar to S. grande (Wight 1841: 17) Walpers (1843: 180), but differs from S. grande in its small habit (4 m tall vs. usually more than 20 m tall), subsessile leaves (vs. petiolate in S. grande) and more or less slightly cordate leaf base (vs. cuneate).

Syzygium phoukhaokhouayense Soulad., Tagane & Yahara, sp. nov. 
 TYPE:—LAOS. Vientiane Province, Thoulakhom district, Ban Pa Paek, Phou Khao Khouay National Protected Area, ...

Syzygium phoukhaokhouayense is similar to S. syzygioides (Miquel 1855: 431) Merrill & Perry (1938: 109) but differs in having coriaceous leaves (vs. chartaceous to subcoriaceous in S. syzygioides), longer petiole (7–12 mm long vs. 3–5 mm long), larger and reddish-purple hypanthium (4.1–4.5 mm long vs. ca. 3 mm long, greenish), longer styles (ca. 5 mm long vs. ca. 8.3 mm long) and fewer ovules per locule in ovary (4–5 per locule in S. phoukhaokhouayense vs. 10–14 per locule in S. syzygioides). Also, it is apparently similar to S. lineatum (De Candolle 1828: 287) Merrill & Perry (1938: 109) but easily distinguished by having more secondary veins (28–32 pairs in S. phoukhaokhouayense vs. 16–20 pairs in S. lineatum) and single intramarginal veins (vs. 2).

Distribution:—Laos (so far only known from Phou Khao Khouay National Protected Area). 
 Habitat and Ecology:—Open pine forest, at 905 m elevation.  

Etymology:— The species epithet refers to the geographical location of the find, Phou Khao Khouay National Protected Area. 
 Vernacular name:— ຫວ້າພູ (Wa Phou). 

Note:— The matK sequence of S. phoukhaokhouayense is identical with S. syzygioides (783/783 bp for GenBank accession no. AB924771 and AB925281, 780 bp for AB924710 and AB924734, 768/768 bp for AB924947). However, S. phoukhaokhouayense is easily distinguished from S. syzygioides by the diagnostic characters mentioned above, such as the differences in leaf thickness, length of petiole and style, and colour of hypanthium.

Syzygium scabrum Tagane, Soulad. & Yahara, sp. nov. 
TYPE:—THAILAND. Buengkan Province, Bung Khla, Phu Wua Wildlife Sanctuary, ...

Syzygium scabrum is similar to S. vestitum Merrill & Perry (1938: 110) in having reddish brown hairs on twigs, leaves and hypanthium, but differs in having more or less cordate leaf base (vs. broadly cuneate to rounded in S. vestitum), scabrid on both sides of leaf surfaces (vs. glabrous except on veins on abaxial side, never scabrid on adaxial side), more secondary veins (16–30 pairs vs. 10–16 pair) and longer styles (8–15.5 mm long vs. 6 mm long).

Distribution:— Laos (Vientiane Province: Phou Khao Khouay National Protected Area), Thailand (Nakhon Phanom Province: Phu Langka National Park, Buengkan Province: Phu Wua Wildlife Sanctuary). 
 Habitat and Ecology:—In hill evergreen forest, at altitudes of 690–770 m in Laos, and in dry evergreen forest at an altitude of 150 m in Thailand. 

 Etymology:—The species epithet refer to its nature of roughened (scabrid) surfaces of twigs and leaves caused by dense hairs. 
 Vernacular name:— หว้าขน (Wa Khon) (Thailand); ຫວ້າຂົນ (Wa Khon) (Laos).

Note 1:—This species has been confused with S. vestitum (type: Mt. Bana, Vietnam, J. & M.S. Clemens 3296, K, image!) by Souladeth & Meesawat (2012), Chantaranothai (2014), and Soh & Parnell (2015), but it is clearly distinguished from S. vestitum by the above diagnostic characters. Syzygium vestitum is restricted to northern to central Vietnam and southern China (southeast Yunnan) (Hô 2003, Chen & Craven 2007, from our field observations in SE Asia). The sequence of matK region of S. scabrum (GenBank accession no. LC381853) differs 7 bp of the total 760 bp from the S. vestitum (LC381852: Tagane et al. V2522 (FU!) from Bach Ma National Park, Central Vietnam, ca. 25 km apart from the type locality of S. vestitum), supporting the separation of the two species.

Tectaria chinensis (Ching & Chu H. Wang) Christenh.
in Dong, Tan, Pham & Phan, 2018. 

Abstract
Tectaria chinensis is a poorly known species from China, with its type being the sole authentic voucher to date. Recent field observations and morphological comparisons reveal its type being an incomplete frond, which resulted in the constant misinterpretation of some morphological characters and the allied species to T. chinensis. In fact, T. chinensis is a very special species restricted in southern China and northern Vietnam and featured by the unique long and erect caudex and the rare combination of partly free venation and vein-dorsal sori. Phylogenetically, T. chinensis was revealed by our previous analyses of five plastid regions to be in the Ctenitopsis group (Clade III or T. subg. Ctenitopsis), forming a sister clade to the lineage of T. fuscipes. A detailed description, explanatory illustrations, as well as distribution and habitat information of T. chinensis are provided.

Tectaria chinensis (Ching & Chu H. Wang) Christenhusz (2010: 58). 
Basionym:— Ctenitopsis chinensis Ching & Chu H. Wang (1981: 124). 
Type:— CHINA. Yunnan: Hekou, in 1955, elev. 100 m, Department of Biology, Yunnan University (DBYU) 512 (holotype PE!)
....

Distribution:—Restricted to southern China and northern Vietnam. In China: southern Yunnan (Hekou, Jinping, Lüchun, Mengla, and Xichou); in Vietnam: Ha Giang (Cao Bo, Vi Xuyen Distr.), Lao Cai (Nam Xe, Van Ban Distr.). This is the first time to confirm T. chinensis in Vietnam. It is also highly expected to find this species in northern Laos.

Note:— The type of Tectaria chinensis, DBYU 512 (PE), is actually an incomplete frond that consists of a broken stipe and a lamina without basal pinnae (Fig. 1). The lowest pinnae seen on the sheet of type specimen was mistakenly regarded as the basal pinnae by Ching & Wang (1981), which leaded them and later authors (Wang 1999, Cheng 2005, Xing et al. 2013) to associate this species with Ctenitopsis subsageniacea sensu Ching (1938: 311) [= T. austrosinensis (Christ 1907: 145) C. Christensen (1934: 177) (Dong 2017)], a species with the basal basiscopic lobes reduced on basal pinnae. Based on the misinterpretation of T. chinensis, we had never associated our new collections featured by long-erect caudices with T. chinensis because in the new collections the basal basiscopic pinnules of basal pinnae are constantly produced (Fig. 2). On the other hand, of all known species in Tectaria from China T. chinensis is the only dubious species which is poorly presented in herbarium; this fact reminded us to connect our new collections featured by remarkable long caudex with T. chinensis. The overall similarity, especially the consistent venation and sori positions between the new collections and the type of T. chinensis makes it sure that our new collections are just the individuals of T. chinensis. Now it is clear that T. chinensis is with the basal basiscopic pinnules being produced on basal pinnae and is not at all similar to T. austrosinensis.

Gordodon kraineri 
Lucas, Rinehart & Celeskey, 2018
  DOI: 10.26879/899 

ABSTRACT
Gordodon kraineri is a new genus and species of edaphosaurid eupelycosaur known from an associated skull, lower jaw and incomplete postcranium found in the early Permian Bursum Formation of Otero County, New Mexico, USA. It has a specialized dental apparatus consisting of large, chisel-like incisors in the front of the jaws separated by a long diastema from relatively short rows of peg-like maxillary and dentary cheek teeth. The dorsal vertebrae of Gordodon have long neural spines that bear numerous, randomly arranged, small, thorn-like tubercles. The tubercles on long neural spines place Gordodon in the Edaphosauridae, and the dental apparatus and distinctive tubercles on the neural spines distinguish it from the other edaphosaurid genera—Edaphosaurus, Glaucosaurus, Lupeosaurus and Ianthasaurus. Gordodon is the oldest known tetrapod herbivore with a dentary diastema, extending the temporal range of that anatomical feature back 95 million years from the Late Triassic. The dental apparatus of Gordodon indicates significantly different modes of ingestion and intraoral transport of vegetable matter than took place in Edaphosaurus and thus represents a marked increase in disparity among edaphosaurids. There were two very early pathways to tetrapod herbivory in edaphosaurid evolution, one toward generalized browsing on high-fiber plant items (Edaphosaurus) and the other (Gordodon) toward more specialized browsing, at least some of it likely on higher nutrient, low fiber plant items. Gordodon shows a surprisingly early specialization of the dental apparatus and indicates how incomplete our knowledge is of edaphosaurid evolution, disparity and diversity.

Gordodon gen. nov.

Etymology.Gordo, Spanish for “fat,” and Greek odon, “tooth,” in reference to the large (“fat”) teeth at the anterior end of the snout of the holotype. Gordo also is a reference to the city of Alamogordo, near the type locality.

Diagnosis. Gordodon is a medium-sized edaphosaur (presacral length ~1 m) distinguished from the other edaphosaurid genera by: an unique dental apparatus consisting of large chisel-like incisors in the premaxilla and dentary (dentary incisors inferred from empty alveolus) separated by a long diastema from a relatively short row of peg-like maxillary and dentary cheek teeth and tooth plates with small (<1 mm) teeth on the interior surface of the mandible; preorbital skull length subequal to postorbital skull length; a relatively short nasal-maxilla suture; cervical and anterior dorsal vertebrae with relatively gracile centra that are double-keeled ventrally; and cervical and dorsal vertebrae have long neural spines that bear up to 12 small, thorn-like lateral tubercles randomly distributed on each side.

Guizhou Odorous Frog  || DOI: 10.7717/peerj.5695 

Abstract
The genus Odorrana is widely distributed in the mountains of East and Southeastern Asia. An increasing number of new species in the genus have been recognized especially in the last decade. Phylogenetic studies of the O. schmackeri species complex with wide distributional range also revealed several cryptic species. Here, we describe a new species in the species complex from Guizhou Province of China. Phylogenetic analyses based on mitochondrial DNA indicated the new species as a monophyly clustered into the Odorrana clade and sister to O. schmackeri, and nuclear DNA also indicated it as an independent lineage separated from its related species. Morphologically, the new species can be distinguished from its congeners based on a combination of the following characters: (1) having smaller body size in males (snout-vent length (SVL) <43.3 mm); (2) head longer than wide; (3) dorsolateral folds absent; (4) tympanum of males large and distinct, tympanum diameter twice as long as width of distal phalanx of finger III; (5) two metacarpal tubercles; (6) relative finger lengths: II < I < IV < III; (7) tibiotarsal articulation reaching to the level between eye to nostril when leg stretched forward; (8) disks on digits with circum-marginal grooves; (9) toes fully webbed to disks; (10) the first subarticular tubercle on fingers weak; (11) having white pectoral spinules, paired subgular vocal sacs located at corners of throat, light yellow nuptial pad on the first finger in males.

Odorrana kweichowensis sp. nov.

Diagnosis: Odorrana kweichowensis sp. nov. is assigned to genus Odorrana based upon molecular phylogenetic analyses and the following morphological characters: dorsum is green; tips of digits dilated, tapering, disks with circum-marginal grooves, and vertical diameter longer than horizontal diameter in the disks; supernumerary tubercle below the base of fingers III and IV; feet fully webbed to disks, without tarsal fold; the first finger thick and nuptial pad distinct.

Odorrana kweichowensis sp. nov. could be distinguished from its congeners by a combination of the following characters: (1) having smaller body size in males (SVL <43.3 vs. SVL >48 mm in many other species); (2) head longer than wider; (3) dorsolateral folds absent; (4) tympanum of males large and distinct, tympanum diameter in males twice as long as width of distal phalanx of finger III; (5) two metacarpal tubercles; (6) relative finger lengths: II < I < IV < III; (7) tibiotarsal articulation reaching to the level between eye to nostril when leg stretched forward; (8) disks on digits with circum-marginal grooves; (9) toes fully webbed to disks; (10) the first subarticular tubercle on fingers weak; (11) having white pectoral spinules, paired subgular vocal sacs located at corners of throat, light yellow nuptial pad on the first finger in males.

(B) Habitats in Xieba Town, Zheng’an County, Guizhou Province, China. (C) Habitats in Shilian Town, Meitan County, Guizhou Province, China. Photographs by S. Z. Li.

Ecology: To present, Odorrana kweichowensis sp. nov. has been found in three localities: Lengshuihe Nature Reserve in Jinsha Co., Meitan Co. and Zheng’an Co. in Guizhou Prov. of China. Geographical distances between these localities were from 89 to 173 km. Population from the Lengshuihe Nature Reserve inhabited broad streams, and near the riparian areas, surrounded by evergreen broadleaved forests (Fig. 10A). Populations from Meitan Co. and Zheng’an Co. inhabited broad slow-flowing rivers surrounded by paddy field (Figs. 10B and 10C). All of the localities were at elevations 717–766 m. All adult individuals that we found appear on the stones in the streams at night (07:30–12:00 pm) with water pH 6.8–7.1 and water temperature 15–23 °C. Tadpoles could be found at daytime and night. Amplexed individuals could be found in the streams in the type locality (Fig. 10A). Three sympatric amphibian species Fejervarya multistriata, Rana zhenhaiensis, and Polypedates megacephalus were found in Meitan Co. and Zheng’an Co., but only one sympatric amphibian species Amolops chunganensis was found in the Lengshuihe Nature Reserve in the type locality.


Etymology: The specific epithet “kweichowensis” refers to the distribution of this species, Guizhou Prov., China. The “kweichow” is an old spelling and a transliteration for “Guizhou.” We propose the common English name “Guizhou Odorous Frog” for this species.


Conclusion: 
We described a new species of the odorous frog genus Odorrana (Amphibia, Anura, Ranidae) from Guizhou Prov. of China, and provide evidence for its phylogenetic allocations. O. kweichowensis sp. nov. was only known from a narrow range in the northwestern part of Guizhou Prov. of China, and occurred from mountain streams at mid and low elevations similar to most odorous frogs. In our fieldwork, the new species was found to be seriously threatened by local villagers and construction of dams and roads. Thus, further more detailed investigations on the species are urgent to ascertain its distributional range and population status. With our description, we contributed to a better knowledge of the diversity of the genus Odorrana in the southwestern China, and thus suggested that more comprehensive phylogeographic studies would highlight radiation patterns of the group.
