 Significance

We report fossil evidence of feather structural protein (beta-keratin) from a 130-My-old basal bird (Eoconfuciusornis) from the famous Early Cretaceous Jehol Biota, which has produced many feathered dinosaurs, early birds, and mammals. Multiple independent molecular analyses of both microbodies and associated matrix recovered from the fossil feathers confirm that these microbodies are indeed melanosomes. We use transmission electron microscopy and immunogold to show localized binding of antibodies raised against feather protein to matrix filaments within these ancient feathers. Our work sheds new light on molecular constituents of tissues preserved in fossils.

Abstract

Microbodies associated with feathers of both nonavian dinosaurs and early birds were first identified as bacteria but have been reinterpreted as melanosomes. Whereas melanosomes in modern feathers are always surrounded by and embedded in keratin, melanosomes embedded in keratin in fossils has not been demonstrated. Here we provide multiple independent molecular analyses of both microbodies and the associated matrix recovered from feathers of a new specimen of the basal bird Eoconfuciusornis from the Early Cretaceous Jehol Biota of China. Our work represents the oldest ultrastructural and immunological recognition of avian beta-keratin from an Early Cretaceous (∼130-Ma) bird. We apply immunogold to identify protein epitopes at high resolution, by localizing antibody–antigen complexes to specific fossil ultrastructures. Retention of original keratinous proteins in the matrix surrounding electron-opaque microbodies supports their assignment as melanosomes and adds to the criteria employable to distinguish melanosomes from microbial bodies. Our work sheds new light on molecular preservation within normally labile tissues preserved in fossils.

Abstract

A new species of goby, Lubricogobius tunicatus, is described from Milne Bay Province, eastern Papua New Guinea, on the basis of 10 adult specimens, 9.1–11.5 mm SL. Diagnostic features include 9 (rarely 10) segmented dorsal-fin rays, 6–7 segmented anal-fin rays, the presence of both anterior and posterior nostrils, the greatest body depth 3.1–3.7 in SL, overall coloration typically pale yellow to whitish (rarely brown), and an exceptionally small maximum size of about 11.5 mm SL. Lubricogobius tunicatus is most similar in appearance to L. nanus Allen, 2015, another diminutive species from Papua New Guinea that differs in having 10–11 dorsal-fin rays and 8–9 anal-fin rays. The new species is apparently invariably associated with a species of tunicate (Polycarpa sp.) on silty-sand bottoms in depths of about 20–28 m. In addition, L. ornatus Fourmanoir, 1966, originally described from Vietnam and also recorded from the Ryukyu Islands in Japan, northern Australia, and New Caledonia, is reported for the first time from the East Indies, based on two specimens collected at Lembeh Strait, North Sulawesi, Indonesia.

Abstract

A new genus from Borneo, Borneocola Y.Y.Sam, is described here. The genus currently contains eight species previously classified as members of the Scaphochlamys Baker. The finding is based on the results of the morphological and molecular studies of Scaphochlamys throughout its geographical range and its closely allied sister groups, Distichochlamys M.F.Newman and Myxochlamys A.Takano & Nagam. Borneocola is nested within the tribe Zingibereae and its monophyly is strongly supported by both ITS and matK sequence data. The genus is characterised by several thin, translucent and marcescent floral bracts, absence of coloured streaks on the labellum and capitate stigma with two dorsal knobs. The genus is distributed in northwest Borneo and all species are very rare and highly endemic.

Keywords: Distichochlamys, Myxochlamys, Scaphochlamys, morphology, phylogeny, taxonomy

Borneocola Y.Y.Sam, gen. nov.

 Diagnosis: Similar to Scaphochlamys and Myxochlamys. Borneocola has thin, translucent and marcescent floral bracts, absence of coloured streaks on labellum and two dorsal knobs on the stigma versus the coriaceous and persistent floral bracts, coloured streaks on labellum and absence of dorsal knobs on the stigma in Scaphochlamys. The mucilage on the floral bracts and the versatile anther of Myxochlamys are absent in Borneocola.

Type species: Borneocola reticosus (Ridl.) Y.Y.Sam, comb. nov.

 Gastrochilusreticosa Ridl., J. Straits Branch Roy. Asiat. Soc. 44: 195 (1905).

Morphology: The Borneocola and Scaphochlamys species look similar in their vegetative morphologies. They are mostly small-sized gingers without the conspicuous pseudostem, with one to several leaves arranged spirally and tightly on a very short stem at the base. So far, all the Borneocola species examined are unifoliate. Similarly, most of the Scaphochlamys species also bear one leaf except for several species which have leafy shoots composed of multiple leaves, for example, S. grandis, S. lanceolata, S. kunstleri, S. malaccana and S. minutiflora. The basal part of the leaves is covered with a few bladeless sheaths which are rather different for both groups in terms of their texture and colour. For Scaphochlamys, the sheaths are coriaceous, green, green with a red tinge or red and mostly persistent until the end of flowering (Figure 4A, B). On the other hand, the sheaths of Borneocola are thinner in texture with a lighter shade of green or brown. The thin sheaths normally dry up early (Figure 4C) and sometimes they are completely shredded during the time of flowering.

Sam.   DOI: 10.3897/phytokeys.75.9837

The inflorescences of Borneocola and Scaphochlamys are terminal, stalked and consisted of few to many floral bracts. The differences lie in the characteristics of the floral bracts and flowers. Borneocola species have thin, translucent, early decaying and marcescent floral bracts. The colours of the bracts can be pink, pale brown, pale or light green (Figure 5A). On the contrary, the bracts of Scaphochlamys are coriaceous and sometimes hard in texture. They are usually green, green tinged red, red or reddish brown and remain fresh throughout the flowering (Figure 5B, C).
.....

Etymology: This new genus is named after the island of Borneo and -cola (Latin) means dweller or inhabitant. This is to recognise the extremely rich and unique biodiversity that is found in Borneo.

Distribution: Borneo. The genus is currently known to occur only in the northwest and possibly central Borneo. Eight species are recorded from Sarawak, Malaysia and many more are undescribed.

Litorosuchus somnii   Li, Wu, Zhao, Nesbitt, Stocker & Wang, 2016    DOI: 10.1007/s00114-016-1418-4

Abstract

Reptiles have a long history of transitioning from terrestrial to semi-aquatic or aquatic environments that stretches back at least 250 million years. Within Archosauria, both living crocodylians and birds have semi-aquatic members. Closer to the root of Archosauria and within the closest relatives of the clade, there is a growing body of evidence that early members of those clades had a semi-aquatic lifestyle. However, the morphological adaptations to a semi-aquatic environment remain equivocal in most cases. Here, we introduce a new Middle Triassic (245–235 Ma) archosauriform, Litorosuchus somnii, gen. et sp. nov., based on a nearly complete skeleton from the Zhuganpo Member (Ladinian [241–235 Ma]) of the Falang Formation, Yunnan, China. Our phylogenetic analyses suggest that Litorosuchus is a stem archosaur closely related to the aberrant Vancleavea just outside of Archosauria. The well-preserved skeleton of L. somnii bears a number of morphological characters consistent with other aquatic-adapted tetrapods including: a dorsally directed external naris, tall neural spines and elongate chevrons in an elongated tail, a short and broad scapula, webbed feet, long cervical vertebrae with long slender ribs, and an elongated rostrum with long and pointed teeth. Together these features represent one of the best-supported cases of a semi-aquatic mode of life for a stem archosaur. Together with Vancleavea campi, the discovery of L. somnii demonstrates a growing body of evidence that there was much more diversity in mode of life outside Archosauria. Furthermore, L. somnii helps interpret other possible character states consistent with a semi-aquatic mode of life for archosauriforms, including archosaurs.

Rubovietnamia nonggangensis  F.J.Mou & D.X.Zhang

ABSTRACT

 A new Rubiaceae species, Rubovietnamia nonggangensis F. J. Mou & D. X. Zhang, is described and illustrated from Guangxi, China. The somatic chromosome number (2n = 22) and pollen morphology of the species are reported. The new species is characterized prominently by having dense hairs on many organs, such as young branches, leaves, and inflorescences, enlarged and foliaceous calyx lobes caducous after anthesis, and indehiscent and globose fruits with persistent yellowish annular floral disks on the apex. All morphological data support that it belongs to the genus Rubovietnamia, a genus distributed in Vietnam and southern China, currently classified in the tribe Gardenieae of the subfamily Ixoroideae.

Narcine baliensis   De Carvalho & White, 2016    DOI:  10.11646/zootaxa.4127.1.8

Abstract

A new species of numbfish, Narcine baliensis, sp. nov., is described from the tropical eastern Indian Ocean from Indonesia. It is superficially similar to N. brevilabiata and N. atzi in aspects of its color pattern, but is distinguished from both congeners in details of its color pattern, in tooth band morphology, and in proportions of its dorsal fins, among other features. Narcine baliensis, sp. nov., is unique in having a dorsal color pattern composed of large, circular, ovoid or elongate dark brown spots or blotches on dorsal disc along with more numerous small (about eye-sized or slightly greater) brownish, subcircular spots, with large blotches and small spots surrounded by a very slender creamy-white pattern, as well as in having broadly circular upper and lower tooth bands of about the same width and shape. The genus Narcine is now composed of 20 valid species, but uncertainty remains concerning the identification and morphological variation of some of its species in the tropical Indo-West Pacific region.

Keywords: Pisces, Narcinidae, lesser electric rays, numbfishes, taxonomy, morphology, Indonesia

Geographical distribution.— Known from four specimens from southern Indonesia. The holotype was collected during the JETINDOFISH Survey (Gloerfelt-Tarp & Kailola, 1984) from between the islands of Bali and Lombok in depths of about 60 m. The paratypes were collected from the Cilacap fishing port in Central Java from bycatch landings of the local trammel net fishery, which operates off southern Java where it is based. The image of the live specimen was taken farther east on the other side of Wallace's line from the island of Komodo.Narcine baliensis probably occurs at least off most of Java and the western Lesser Sunda Islands, therefore crossing Wallace's line between Bali and Lombok. As far as presently known, N. baliensis and the Australian species of Narcine (= Narcinops Whitley, 1940; Carvalho et al., unpubl.) are the only numbfishes to occur east of the line.

Etymology.— Named in reference to the nearby island of Bali, close to the type locality between the islands of Bali and Lombok, Indonesia.

Zaglossus attenboroughi  Flannery & Groves, 1998    DOI:  10.1515/mamm.1998.62.3.367

Abstract

A systematic revision of monotremes of the genus Zaglossus has revealed unexpected morphological diversity. Statistical and non-metric analysis indicate that three species can be recognised: Zaglossus bruijnii (Peters and Doria, 1876), which inhabits the Vogelkop, Fak Fak and possibly the Charles Louis Mountains regions; Zaglossus bartoni Thomas, 1907, which occurs on the central cordillera between the Paniai Lakes and the Nanneau Range, as well as the Huon Peninsula; and Zaglossus attenboroughi n. sp. from the Cyclops Mountains. Four distinct subspecies of Z. bartoni can be discerned. The three subspecies inhabiting the central cordillera increase in size from east to west: Z. bartoni smeenki n. ssp. of the Nanneau Range being the smallest, the nominotypical form intermediate in size, and Z. bartoni diamondi n. ssp. the largest. Zaglossus b. clunius inhabits the Huon Peninsula.

Eigenmannia besouro  Peixoto & Wosiacki, 2016  DOI: 10.11646/zootaxa.4126.2.6

Abstract

A new species of the Eigenmannia trilineata species-group is described from the rio São Francisco basin, Brazil. It is distinguished from closely related species by a unique set of characters, including a subterminal mouth, the presence of ii,13–14 pectoral-fin rays, a coronomeckelian bone that is 30% the length of Meckel’s cartilage, the specific pattern of the dentition of the premaxilla and dentary, and the more anterior origin of the superior midlateral stripe. Comments on species of the E. trilineata species-group are presented.

Manamendra-Arachchi’s Whistling Lizard  | Calotes manamendrai  Amarasinghe & Karunarathna, 2014  FIG. 4. — Calotes manamendrai sp. nov., a live female (not collected) at the type locality (Riverstone, Knuckles massif, Sri Lanka). DOI:  10.1655/HERPETOLOGICA-D-13-00087

ABSTRACT 

Based on morphological evidence, we describe a new species of agamid lizard of the genus Calotes that is restricted to a single site on the northern face of the Knuckles massif (~1000 m above sea level) of Sri Lanka. The genus Calotes consists of eight species in Sri Lanka, six of which appear to form an endemic radiation. The new species, Calotes manamendrai, most closely resembles Calotes liolepis Boulenger, 1885, which is widely distributed in mid-elevations in the central highlands, lowland rain forests, and a few isolated moist forests in the dry zone of Sri Lanka. Females of Calotes manamendrai sp. nov. differ from the females of Calotes liolepis in having nonenlarged pectoral scales; keeled dorsal scales on the body; smaller midgular scales than the rest of the throat scales; brown color, seven distinct stripes each side on gular area; black color shoulder pit; and upper arm with carinate ventral scales. Finally, we provide a complete redescription for Calotes liolepis based on the adult female syntypes.

Keywords: Agamidae, Biogeography, Calotes manamendrai sp. nov, Conservation, Knuckles massif, Systematics

Etymology.— The species epithet is an eponym Latinized in the genitive singular, honoring Kelum Nalinda Manamendra–Arachchi for his generous teaching and guidance in taxonomic studies for the first two authors as well as his remarkable contributions to herpetology, zooarchaeology, and biodiversity conservation in Sri Lanka. Suggested English name: Manamendra-Arachchi’s Whistling Lizard; Sinhala (local) name: Manamendra-Arachchige Uruwan Katussa.

ABSTRACT

 Recent botanical exploration in eastern Malesia has resulted in the discovery of three spectacular palm taxa that have proved difficult to assign to genus. New evidence from molecular phylogenetic research indicates that these taxa should now be recognised as three monotypic genera. Here, we describe these genera as new to science, all of which are members of subtribe Ptychospermatinae (Areceae: Arecoideae). Jailoloa Heatubun & W. J. Baker is restricted to ultramafic vegetation in a single site in Halmahera and is Critically Endangered due to nickel mining. Manjekia W. J. Baker & Heatubun is scattered throughout the limestone vegetation of Biak Island, east of the Bird's Head Peninsula of New Guinea, and is Endangered, although parts of its distribution fall within a protected area. Wallaceodoxa Heatubun & W. J. Baker, named to mark the centenary of Alfred Russel Wallace's death, is found on Gag and Waigeo, two of the Raja Ampat Islands west of the Bird's Head Peninsula, where it is Critically Endangered due to its small and rapidly reducing population. Full morphological descriptions are provided with detailed comparisons with related genera, alongside a revised key to the genera of Ptychos-permatinae. These new genera are unexpected additions to the palm flora of Malesia, and demand urgent conservation attention.

ETYMOLOGY. The generic name commemorates Alfred Russel Wallace, the great English naturalist and codiscoverer of the theory of evolution by natural selection, who visited Waigeo in the Raja Ampat Islands in 1860 during his celebrated Malay Archipelago travels (Wallace 1869; van Wyhe 2013). This eponymy marks the centenary of his death on 7 November 1913. The generic name is derived by suffixing Wallace’s surname with the Greek word (-doxa) to mean “to the glory of Wallace”

Hohenbergia mesoamericana   I. Ramírez, Carnevali et Cetzal

Abstract

Hohenbergia mesoamericana I. Ramírez, Carnevali et Cetzal is proposed as new, described, and illustrated. Because the genus was previously known only from the Antilles, Colombia, Venezuela, and Brazil, this new species represents the first record of Hohenbergia for Mexico and Mesoamerica. The new species is morphologically similar to the Jamaican H. spinulosa Mez in having the bracts subtending the spikes far exceeding them (especially the lowermost) and green petals, but differs in several characters, including a more elongate peduncle and rachis resulting in a less dense infl orescence, shorter floral bracts, and pedicellate spikes. The conservation status of the new species is evaluated as critically endangered (CR) according to IUCN criteria. 

Key words: Bromelioideae, biogeographical disjunction, conservation, IUCN criteria, Mexico, Yucatán Peninsula.

Resumen. Hohenbergia mesoamericana I. Ramírez, Carnevali et Cetzal se propone como especie nueva, se describe y se ilustra. El género era conocido solamente de las Antillas, Brasil, Venezuela y Colombia; por ello, este nuevo taxón representa el primer registro de Hohenbergia para Mesoamérica y México. Hohenbergia mesoamericana es morfológicamente similar a H. spinulosa Mez de Jamaica, por presentar las brácteas de las espigas muy largas (especialmente las basales) y los pétalos verdes. Sin embargo, difi ere de ella en varios caracteres, incluyendo el pedúnculo y raquis de la infl orescencia más largos, brácteas fl orales más cortas y espigas pediceladas. El estado de conservación de la especie nueva es evaluado como críticamente amenazado (CR) según los criterios del IUCN.

Stenocercus omari   Venegas, Echevarría, García-Burneo & Koch,  2016    DOI:  10.11646/zootaxa.4205.1.4

 Abstract

We describe a new species of Stenocercus from the montane forest of the right margin of the Marañón river in the northern portion of the Central Andes in northern Peru (Amazonas and La Libertad departments), at elevations ranging from 2300 to 3035 m. Stenocercus omari sp. nov. differs from other Stenocercus species, with the exception of S. amydrorhytus, S. chrysopygus, S. cupreus, S. johaberfellneri, S. latebrosus, S. melanopygus, S. modestus, S. ornatissimus, S. orientalis, and S. stigmosus, by having granular scales on the posterior surfaces of thighs, a conspicuous antehumeral fold and by lacking a vertebral crest. However, Stenocercus omari sp. nov. is easily distinguished from the aforementioned species, except S. orientalis, by the presence of prominently keeled dorsal head scales. The new species differs from S. orientalis by lacking a prominent oblique neck fold and by having a distinct deep postfemoral mite pocket.

Abstract

Historically, the taxonomic study of the Asian genus Fordiophyton has had some gaps. Several specimens from Guangdong (China) have been misidentified as Fordiophyton brevicaule C. Chen. The new species proposed here shares with F. brevicaule the densely hirsute stem, rosetted leaves and glabrous hypanthia, but it is distinguished by its glabrous leaves, winged petioles, oblong petals lacking a single trichome at the apex, and purplish anthers in the longer set of stamens. The phylogenetic analyses indicate that it is a member of Fordiophyton and sister to F. brevicaule. Based on morphological and molecular data, we here recognize it as a new species, Fordiophyton zhuangiae S. Jin Zeng & G. D. Tang, which is described and illustrated.

Amanita castanea   Thongbai, Tulloss, Raspé & K.D. Hyde   DOI: 10.11646/phytotaxa.286.4.1

Abstract

Mushrooms belonging to the genus Amanita were collected during a fungal biodiversity study in northern Thailand in 2012–2014. Morphological characteristics and molecular phylogenetic analyses were used to identify the mushrooms to species. Amanita castanea is described as new to science and compared with phenetically and phylogenetically similar species. It is assignable to Amanita stirps Citrina within Amanita series Mappae. Four other species, A. concentrica, A. rimosa, A. cf. rubromarginata and A. zangii are first reports for Thailand; detailed morphological and molecular data are provided for the Thai material.

Key words: Amanitaceae, ectomycorrhizal fungi, morphology, phylogeny

Discussion 

In the present study, we document a novel species and four first records of Amanita species in northern Thailand. Species circumscriptions and identification are supported by both phylogenic and morphological evidence. One interesting exception might be Amanita cf. rubromarginata. The characteristics of the Thai collections, especially the colors of the pileus, agree well with the type description. However, additional collections made in southwestern Japan indicate that the colors of aging A. rubromarginata might be more different from the Thai collections than originally thought. According to illustrations in the recent book of SE Japanese fungi (Terashima et al. 2016), the center of the cap can be nearly black and the margin, olive. These colors were never observed in the Thai material. Therefore, more collections should be made from Thailand to assess the color variation.

 Further molecular studies with multiple genes that avoid loci of the nuclear ribosomal DNA cistron and expanded taxon sampling are needed to resolve the tree topology for some Amanita sections, e.g. Amanita sect. Caesareae(Sánchez-Ramírez et al. 2014, 2015), A. sect. Validae series Mappae (Drehmel et al. 1999, Hughes et al. 2013, Tulloss & Yang 2016d), A. sect. Lepidellasensu Bas (Tulloss et al. 2016) and A. sect. Phalloideae (Cai et al. 2014, Tulloss et al. 2016). A possible set of four protein-coding loci was proposed by Sánchez-Ramírez et al. (2014) and utilized in (Sánchez-Ramírez et al. 2015).

Perissoderma triangulum  Xing, Shih, Zhao & Ren, 2016 DOI:  10.11646/zootaxa.4205.2.7

Abstract

Two new genera, each with a new species, Perissoderma triangulum gen. et sp. nov. and Abrderma gracilentum gen. et sp. nov., of the family Protodiplatyidae are described from the latest Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China. They are the first records of Protodiplatyidae from the latest Middle Jurassic Daohugou locality. Both new genera are assigned to Protodiplatyidae based mainly on diagnostic characters of antennae, pronotum, tegmina, tarsi and the distinct long, slender, multi-segmented cerci. We summarize the distributions and ages of all described fossil Archidermaptera and infer that the Dermaptera might have originated in Eurasia and started their diversification and migration to a worldwide distribution. The new taxon of Abrderma gracilentum gen. et sp. nov. provides one more example of an early earwig with well-preserved pentamerous tarsi on the hind leg.

Chalybea brevipedunculata  Penneys, C. Ulloa & D. FernándezDOI:  10.11646/phytotaxa.212.4.2

 Abstract

A new species, Chalybea brevipedunculata, from the Ecuador-Peru border is herein described and illustrated. It differs from all other species in the genus by having inflorescence peduncles that are shorter than their subtending leaf petioles.

Keywords: Chalybea, Melastomataceae, Andes, Cordillera del Cóndor, endemic, Ecuador, Eudicots

Chalybea brevipedunculata Penneys, C. Ulloa & D. Fernández, sp. nov.  

Type:— ECUADOR: Zamora-Chinchipe: Paquisha Cantón. Cordillera del Cóndor. The Machinaza Plateau, 2315 m, 23 Jun 2009 (fl), David Neill & Camilo Kajekai 16913 (Holotype: QCNE!; Isotypes: CAS!, MO!).

Diagnosis:— Differs from all other species of Chalybea by having inflorescence peduncles that are shorter than their subtending petioles.

Etymology:— The specific epithet refers to the short peduncles of the inflorescences, unique among all species of Chalybea. All other members of this genus have peduncles much longer than their subtending petioles.

Valencia robertae  Freyhof,  Kärst & Geiger, 2014

Valencia robertae, new species, from the lower Pinios in northern Peloponnese and Mornos Rivers in southern mainland of Greece is distinguished from V. letourneuxi and V. hispanica by having short lateral bars or vertically elongated small blotches along the midlateral body and an almost triangular anal fin in females, prominent lateral bars between the axial blotch and the caudal-fin base and a long anal fin reaching almost or to the first caudal-fin rays in males larger than 27 mm SL. It is also distinguished by 32 fixed, diagnostic nucleotide substitutions in the mtDNA COI barcode region.
