    Heteropteryx dilatata  (Parkinson, 1798)


    Abstract  

    The areolate Oriental family Heteropterygidae Kirby, 1893 is critically reviewed and the results of the present study contradict the arrangement suggested by Zompro (2004), but in most aspects agree with a molecular study presented by Whiting et al (2003) and a phylogenetic study presented by Bradler (2009). The family is critically discussed and new hypotheses are presented for the phylogeny and intra-familiar relationships, placing the subfamily Dataminae Rehn & Rehn, 1939 as the basalmost clade of Heteropterygidae. The subfamilies Obriminae Brunner v. Wattenwyl, 1893 and Heteropteryginae Kirby, 1893 together represent the sister-group of Dataminae. Arguments and a tree are presented to support this hypothesis. New diagnoses and lists of genera are provided for all three subfamilies contained in Heteropterygidae, along with keys to distinguish between them.

            The subfamily Obriminae is critically reviewed and the distinction between the three tribes Obrimini Brunner v. Wattenwyl, 1893, Eubulidini Zompro, 2004 and Miroceramiini Zompro, 2004 introduced by Zompro (2004) is shown to be poorly supported. While Obrimini sensu Zompro, 2004 is generally accepted (but now also contains genera that were placed in Eubulidini or Miroceramiini by Zompro (2004)), the tribes Eubulidini and Miroceramiini are not supported. A new arrangement is introduced, which is based on morphological characters neglected or overlooked by Zompro (2004) but were partly discussed by Bradler (2009). The genus Mearnsiana Rehn & Rehn, 1939 is removed from Miroceramiini and transferred to Obrimini. The genera Eubulides Stål, 1877Heterocopus Redtenbacher, 1906Theramenes Stål, 1875 and Stenobrimus Redtenbacher, 1906 are removed from Eubulidini and also transferred to Obrimini. Consequently, Eubulidini is synonymised with Obrimini (n. syn.). Miroceramiini is a monotypical tribe and only includes the Wallacean genus Miroceramia Günther, 1934. The new tribe Tisamenini n. trib. is established for the three basal genera Tisamenus Stål, 1875Ilocano Rehn & Rehn, 1939 and Hoploclonia Stål, 1875 all of which were placed in Eubulidini by Zompro (2004). The latter genus differs from the other two genera by the morphology of the female genitalia, which is unique amongst the entire family. Three generic groups are recognized within Obrimini, the Obrimus-group, Stenobrimus-group and Theramenes-group. Keys are presented to distinguish between the three tribes now contained in the Obriminae, i.e. Obrimini, Tisamenini n. trib. and Miroceramiini. The genus Hennobrimus Conle, 2006 is synonymised with Mearnsiana Rehn & Rehn, 1939, based on the fact that the type-species of both genera are conspecific (n. syn.). Hennobrimus hennemanni Conle, 2006, the type-species of Hennobrimus, and Trachyaretaon manobo Lit & Eusebio, 2005 are synonymised with Mearnsiana bullosa Rehn & Rehn, 1939, the type-species of Mearnsiana (n. syn.).Theramenes dromedarius Stål, 1877 from the Philippines is removed from synonymy with the Wallacean Theramenes olivaceus (Westwood, 1859) and re-established as a valid species (rev. stat.).

            The subfamily Heteropteryginae Kirby, 1896 is revised at the species-level and a new diagnosis is presented. Keys to the two genera and all 16 known species are provided along with new descriptions, differential diagnoses, lists of examined material, detailed information on the known distributions, measurements and illustrations of the insects and eggs. The intra-subfamiliar and intra-generic relationships are discussed and a cladogram is presented. Heteropteryginae contains two genera: Heteropteryx Gray, 1835 (Type-species: Phasma dilatatum Parkinson, 1798) and Haaniella Kirby, 1896 (Type-species: Phasma (Heteropteryx) muelleri de Haan, 1842). The distribution of this subfamily is restricted to Sundaland with the exception of a single species that is found in Vietnam. All other species are distributed in Borneo, Sumatra, the Mentawai Islands, Singapore, Peninsular Malaysia and Thailand. Heteropteryginae contains the largest and most striking members of the entire family Heteropteryginae, some of which are amongst the heaviest insects known. The subfamily is characterized by apomorphies such as the presence of wings, having a tympanal area (= stridulatory organ) in the basal portion of the alae, straight profemora, strongly shortened tarsi, lack of rough sensory-areas on the prosternum and typically X-shaped micropylar plate of the eggs. The sister-group of Heteropteryginae is represented by the Obriminae, with which it shares a beak-like secondary ovipositor in the females and presence of a medio-apical spine on the area apicalis. Both features are synapomorphies of Heteropteryginae + Obriminae.

            The genus Haaniella Kirby, 1904 contains 16 known species, five of which are newly described herein. The genus Miniopteryx Zompro, 2004 (Type-species: Haaniella parva Günther, 1944) is synonymised with Haaniella on the basis that the distinguishing feature mentioned in the original description is a character that is frequently found throughout the genus (n. syn.). The type-species H. parva Günther, 1944 is automatically retransferred to Haaniella (rev. stat.). Haaniella aculeata n. sp. from western Sumatra is described from the male. Haaniella macroptera n. sp. from Singapore and the Johor state in southern Peninsular Malaysia is described from both sexes and the eggs. Haaniella gintingi n. sp. from Central Sumatra is described from both sexes and the eggs and Haaniella kerincia n. sp. from Western Sumatra is described from the insects only, the eggs being still unknown. One new species, Haaniella gorochovi n. sp., is the only representative of the genus and subfamily Heteropteryginae known from Vietnam and both sexes as well as the eggs are described. Haaniella erringtoniae (Redtenbacher, 1906) is endemic in Peninsular Malaysia, here removed from synonymy with H. muelleri(de Haan, 1842) and re-established as a valid species (rev. stat.). The Sumatran Haaniellaglaber(Redtenbacher, 1906) is removed from synonymy with H. muelleri (Haan, 1842) and re-established as a valid species (rev. stat.). Leocrates glaber Redtenbacher, 1906 and Haaniella muelleri simplex Günther, 1944 are removed from synonymy with H. muelleri (Haan, 1842) (rev. stat.) and synonymised with H. glaber.Haaniellamecheli(Redtenbacher, 1906) andH. rosenbergii(Kaup, 1871) are removed from synonymy with H. muelleri (Haan, 1842) and re-established as valid species (rev. stat.). Haaniella erringtoniae novaeguineaeGünther, 1934 and Haaniella muelleri var. b. (Haan, 1842) are synonymized with H. rosenbergii (Kaup, 1871) (n. syn.). The type-species Haaniella muelleri (Haan, 1842) is shown to be a fairly rare species that is restricted to Sumatra. All subsequent records of H. muelleri from outside Sumatra and references to captive breeding of stock originating from Peninsular Malaysia in Europe relate to H. erringtoniae (Redtenbacher, 1906). The previously unknown males and eggs of H. rosenbergii (Kaup, 1871) as well as the previously unknown females and eggs of H. parva Günther, 1944 are described and illustrated for the first time. Based on morphological characters of the insects and eggs three distinct species-groups are recognized within Haaniella. The muelleri species-group contains nine species that are distributed throughout Sumatra, the Mentawei Islands, Singapore and Peninsular Malaysia. These are characterized by the smooth ventral surface of the meso- and metafemora and lemon-shaped eggs which entirely lack the setae seen in the two other species-groups. The grayii species-group comprises four species, two of which are endemic in Borneo, one endemic in Sumatra and the fourth species being the only known representative of the subfamily in Vietnam. These species are characteristic for the prominent pair of spines on the abdominal tergites II–IV of males and long apically multidentate epiproct of females. The echinata species-group contains three exceptionally Bornean species, which are characterized by the long and apically pointed subgenital plate of females, which clearly projects beyond the epiproct, as well as the sub-basal lateral tooth of the anal segment of males. The muelleri species-group is sister to the remainder two species-groups.

            Heteropteryx Gray, 1853 is a monotypical genus and only contains the type-species H. dilatata (Parkinson, 1798), which is found throughout Peninsular Malaysia, Thailand, Sumatra and Northeastern Borneo. This genus differs from Haaniella by the strongly conically elevated head, which posteriorly projects over the anterior margin of the pronotum, females being bright green or yellow in colour with plain and translucent pink alae and having distinct spines on the abdominal tergites, and males having a strongly shortened mesothorax and dull pink alae. 

    Lectotypes are designated for Haaniella parva Günther, 1944, Heteropteryx echinata Redtenbacher, 1906, Heteropteryx saussurei Redtenbacher, 1906 and Heteropteryx scabraRedtenbacher, 1906 to guarantee stability of these names.

            Information on the habitats, host-plants, biology, life cycle, parasitism and captive breeding of the species of Heteropteryginae is presented and a list summarising all taxonomic changes presented herein.

    Thismia inconspicua Sochor & Dančák


    Abstract

    A new species belonging to the mycoheterotrophic genus Thismia is described and illustrated. Thismia inconspicua was found in a lowland mixed dipterocarp forest in Ulu Temburong National Park, Brunei Darussalam. It is characterized by its sepia-brown perianth with free equal lobes with very short terminal appendages, two pairs of appendages on connective apices, perianth tube displaced from the ovary axis and short stem. DNA sequence data from commonly studied nuclear and mitochondrial loci are provided. Phylogenetic analysis confirmed the close relationship with other members of section Thismia, subsection Odoardoa. An updated determination key of Thismia species of Borneo is included.

    Keywords: atpA, Burmanniaceae, Malesia, SSU rDNA, Monocots, Borneo

    Thismia inconspicua Sochor & Dančák, sp. nov.

    Thismia inconspicua differs from congeneric species in having the following combination of morphological traits: short stem, all perianth lobes free and equal, tapering into very short terminal appendages, perianth tube displaced from the ovary axis, two pairs of dimorphic appendages on connective apices, three-lobed stigma with lobes entire or bifid.

    Etymology:— The specific epithet reflects the inconspicuous colour and appearance of the plants on decaying wood during flowering period.

    Tylonycteris tonkinensis  
     Tu, Csorba, Ruedi & Hassanin, 2017

     DOI:  10.5852/ejt.2017.274 

    Abstract 

    In Southeast Asia, bats of the genus Tylonycteris Peters, 1872 have traditionally been classified into two wide-ranging species, T. pachypus (Temminck, 1840) and T. robustula Thomas, 1915. Our comparative phylogeographic analyses based on two mitochondrial and seven nuclear genes, combined with our multivariate morphological analyses, show that these species actually represent cryptic species complexes that share a similar biogeographic history in three major regions, i.e., Sundaland, southern Indochina, and northern Indochina. Our molecular dating estimates suggest that Pleistocene climatic oscillations and sea level changes have repeatedly isolated ancestral populations of Tylonycteris spp. in distant bamboo forest refugia. The analyses indicate, however, that populations of the T. pachypus complex were less affected by forest fragmentation in mainland Southeast Asia than those of the T. robustula complex. Accordingly, we propose several taxonomic changes within the genus Tylonycteris: the species T. fulvida and T. malayana are revalidated, and a new species, Tylonycteris tonkinensisTu, Csorba, Ruedi & Hassanin sp. nov., endemic to northern Indochina, is described.

    Etymology: The specific epithet refers to the current restricted occurrence of the new species in north-eastern Laos and northern Vietnam (Fig. 1). The Vietnamese portion of this region was previously called “Tonkin” during the Nguyễn dynasty and French colonial era (from the 19th to the mid-20th centuries) to separate it from the country’s centre (Annam) and southern regions (Cochinchina). The proposed English name is “Tonkin’s Greater Bamboo Bat” and the proposed Vietnamese name is ‘Dơi ống tre Bắc Bộ’.

    Abstract
    We mapped the inferred long-distance migrations of four species of Amazonian goliath catfishes (Brachyplatystoma rousseauxiiBplatynemumB. juruense and B. vaillantii) based on the presence of individuals with mature gonads and conducted statistical analysis of the expected long-distance downstream migrations of their larvae and juveniles. By linking the distribution of larval, juvenile and mature adult size classes across the Amazon, the results showed: (i) that the main spawning regions of these goliath catfish species are in the western Amazon; (ii) at least three species — B. rousseauxiiB. platynemum, and B. juruense — spawn partially or mainly as far upstream as the Andes; (iii) the main spawning area of B. rousseauxii is in or near the Andes; and (iv) the life history migration distances of B. rousseauxii are the longest strictly freshwater fish migrations in the world. These results provide an empirical baseline for tagging experiments, life histories extrapolated from otolith microchemistry interpretations and other methods to establish goliath catfish migratory routes, their seasonal timing and possible return (homing) to western headwater tributaries where they were born.

     Transylvanian giant azhdarchid pterosaur Hatzegopteryx sp. preys on the rhabdodontid iguanodontian Zalmoxes. Because large predatory theropods are unknown on Late Cretaceous Haţeg Island, giant azhdarchids may have played a key role as terrestrial predators in this community. 

    Abstract

    Azhdarchid pterosaurs include the largest animals to ever take to the skies with some species exceeding 10 metres in wingspan and 220 kg in mass. Associated skeletons show that azhdarchids were long-necked, long-jawed predators that combined a wing planform suited for soaring with limb adaptations indicative of quadrupedal terrestrial foraging. The postcranial proportions of the group have been regarded as uniform overall, irrespective of their overall size, notwithstanding suggestions that minor variation may have been present. Here, we discuss a recently discovered giant azhdarchid neck vertebra referable to Hatzegopteryx from the Maastrichtian Sebeş Formation of the Transylvanian Basin, Romania, which shows how some azhdarchids departed markedly from conventional views on their proportions. This vertebra, which we consider a cervical VII, is 240 mm long as preserved and almost as wide. Among azhdarchid cervicals, it is remarkable for the thickness of its cortex (4–6 mm along its ventral wall) and robust proportions. By comparing its dimensions to other giant azhdarchid cervicals and to the more completely known necks of smaller taxa, we argue that Hatzegopteryx had a proportionally short, stocky neck highly resistant to torsion and compression. This specimen is one of several hinting at greater disparity within Azhdarchidae than previously considered, but is the first to demonstrate such proportional differences within giant taxa. On the assumption that other aspects of Hatzegopteryx functional anatomy were similar to those of other azhdarchids, and with reference to the absence of large terrestrial predators in the Maastrichtian of Transylvania, we suggest that this pterosaur played a dominant predatory role among the unusual palaeofauna of ancient Haţeg.

Because large predatory theropods are unknown on Late Cretaceous Haţeg Island, giant azhdarchids may have played a key role as terrestrial predators in this community.

    Diyutamon cereum 

    Abstract

    A new genus and species of freshwater crab, Diyutamon cereum n. gen., n. sp., is described from a cave in Guizhou, China. This is the first record of a true stygomorphic crab from China and East Asia, possessing pale body coloration, strongly reduced eyes, and long ambulatory legs. While superficially similar to Chinapotamon Dai & Naiyanetr, 1994, and Tiwaripotamon Bott, 1970, the new genus possesses a diagnostic combination of carapace, ambulatory leg, thoracic sternal, and male abdominal characters that easily distinguishes it from other genera. Molecular data derived from the mitochondrial 16S rDNA supports the establishment of the new genus.

    Impatiens tanintharyiensis  
    Ruchisansakun, Suksathan & Saw-Lwin


    Abstract

    Impatiens tanintharyiensis Ruchisansakun, Suksathan & Saw-Lwin from the Tanintharyi region of Southern Myanmar is described and illustrated as a new species. The presence of connate lateral united petals and a four-locular ovary, as well as results of molecular phylogenetic analyses of nuclear ITS and plastid atpB-rbcL spacer DNA sequences, suggest that the new species is a member of Impatiens section Semeiocardium (Zoll.) S.X. Yu & Wei Wang. The new species is morphologically most similar to I. spectabilis Triboun & Suksathan, but can be distinguished by its asymmetric flowers, saccate-bucciniform lower sepal, and shorter, slightly incurved spur. Floral traits, including the presence of a large floral chamber with a wide entrance, are consistent with the bee-pollination syndrome in Impatiens. Since I. tanintharyiensis is only known from two small populations, its conservation status is assessed as Endangered.

    Impatiens tanintharyiensis Ruchisansakun, Suksathan & Saw-Lwin is morphologically similar to I. spectabilis Triboun & Suksathan but can be distinguished by having asymmetric flowers due to anticlockwise distorted lateral united petals, a saccate-bucciniform lower sepal, and a shorter, slightly incurved spur. 

    Type:— MYANMAR. Tanintharyi Region: Dawei, Thet Kal Kwet Village. ...

    Distribution:— Endemic to Southern Myanmar (Tanintharyi Region), only known from two localities.
    Ecology:— Growing among decaying organic material on low granular metamorphic rock of granitic schist facies (Phongphat Prasong, pers. comm), along a waterfall at 146–155 m above sea level.

    Etymology:— The specific epithet refers to its locality, the Tanintharyi region of Myanmar.
    Common name:— Tanintharyi Dan Pan, Tanintharyi balsam. 

    Pollination ecology:— A recent comparative study of floral morphology and pollination ecology demonstrated that the closely related and morphologically similar I. daraneenae, is pollinated by bees (Ruchisansakun et al. 2016). The presence of a large floral chamber with a wide entrance are traits associated with bee pollination in Southeast Asian Impatiens (Ruchisansakun et al. 2016). Based on the traits of the new species, we hypothesize that the new species is also bee-pollinated.

    Landdroskop Mountain Toadlet  | Capensibufo magistratus 
      Channing, Measey, de Villiers, Turner & Tolley, 2017 

    Abstract 

    A molecular and morphological study of the Mountain Toadlets, previously included in Capensibufo rosei, showed that there are several previously unrecognised species in this group. We describe three new species from the Hawekwas, Hottentots-Holland, Groenland and Riviersonderend Mountains; the DuToitskloof Mountains, and the Akkedis, Koeël and Kleinriviers Mountains, South Africa. Capensibufo rosei is restricted to the Table Mountain chain of the Cape Peninsula.

    Keywords: Amphibia, Capensibufo rosei, new species, South Africa


    Capensibufo deceptus sp. nov. 
    Deception Peak Mountain Toadlet

    Etymology. This species is named for the type locality, below Deception Peak, DuToits Mountains, South Africa. The specific epithet is Latin for 'deceive'.


    Capensibufo selenophos sp. nov. 
    Moonlight Mountain Toadlet

    Etymology. The specific epithet derives from the Greek selenóphos (moonlight), in reference to the type locality Maanskyn Nature Reserve (Afrikaans maanskyn = moonlight). It is used as a noun in apposition.



    Capensibufo magistratus sp. nov.
    Landdroskop Mountain Toadlet

    Etymology. The specific epithet derives from the Latin magister (magistrate), referring to the type locality, Landdroskop. The Afrikaans Landdroskop = Magistrates Peak. It is used as a noun in apposition.

    Phycocharax rasbora
    Ohara, Mirande & de Lima, 2017 


    Abstract
    A new genus and species of characid fish is described from rio Braço Norte, a tributary of rio Teles Pires, Tapajós basin, Mato Groso, Brazil. The new taxa can be diagnosed from the remaining characids by a unique combination of characters that includes the presence of a single row of relatively compressed premaxillary teeth, large teeth with four to nine cusps on premaxillary and dentary, absence of pseudotympanum, incomplete lateral line with 7–13 pored scales, sexually-dimorphic males with distal margin of anal fin approximately straight, and presence of a nearly triangular and horizontally elongated blotch from the posterior half of the body to caudal peduncle. The most parsimonious phylogenetic hypothesis, using morphological data, recovered the new genus and species in a clade including Paracheirodon axelrodi and Hyphessobrycon elachys.

    Family Characidae Agassiz

    Phycocharax, new genus.

    Type species: Phycocharax rasbora, new species, by monotypy and original description.

    Diagnosis: Phycocharax can be diagnosed from the remaining characid genera by the combination of the following character-states, none of them unique: 1) presence of single row of relatively compressed premaxillary teeth (Fig 2); 2) large teeth on premaxillary, and dentary with four to nine cusps (Fig 2); 3) pseudotympanum absent; 4) incomplete lateral line with 7–13 pored scales; 5) anal fin dimorphic, males with distal margin approximately straight, and decreasing gently posteriorly (Figs 1a and 3a), while females present slightly concave margin of anal fin with anteriormost branched rays distinctly longer than remaining rays (Figs 1b and 3b); 6) presence of horizontally-elongated somewhat triangular blotch extending from vertical through dorsal-fin terminus to caudal peduncle end (Figs 1 and 3).

    Etymology: From the Greek phykos, meaning “algae”, in allusion to the feeding habit of the new taxon owing to the dominance of this resource in its stomach contents, plus charax, meaning “pointed stake” or “palisade of pointed sticks”, the first generic name in Characidae. Gender masculine.


    Phycocharax rasbora, new species.

    Distribution: Phycocharax rasbora is so far known only from its type locality at upper rio Braço Norte, a right-bank tributary of the rio Peixoto de Azevedo, part of rio Teles Pires drainage, rio Tapajós basin (Fig 5). The rio Braço Norte drains the Serra do Cachimbo at northern Mato Grosso State, Brazilian Amazon.

    Etymology: From the Bengali word “rasbora”, the common name of the fish Rasbora rasbora (Hamilton). Rasbora is a generic name encompassed a great radiation of small cyprinids from southeastern Asia, including the species currently allocated in the genus Trigonostigma, which possess a dark triangular blotch on body sides very reminiscent in shape and position similarly as found in the new species. Gender masculine. A noun in apposition.

     Triunfosaurus leonardii 
    Carvalho, Salgado, Lindoso, Araújo-Júnior, Nogueira & Soares, 2017


    Highlights
    • A new Gondwanan Early Cretaceous (Berriasian – early Hauterivian) dinosaur species is described.
    • The specimen comes from the Rio Piranhas Formation, Triunfo Basin - Brazil.
    • It is one of the oldest described basal titanosaur ever recorded in Gondwana.
    • The discovery reinforces the South American origin for Titanosauria during the early Cretaceous.

    Abstract
    Although dinosaurian ichnofaunas are common in the Northeastern Brazilian Interior Basins, osteological remains are poorly represented in these areas. One of the main challenges in vertebrate paleontology in the Lower Cretaceous of this region is to recognize body-fossils, which can unveil the anatomy, functional morphology and paleoecological aspects of the dinosaurian fauna recorded until now only by footprints and trackways. The discovery of a new dinosaur specimen in the Rio Piranhas Formation of the Triunfo Basin opens new perspectives into the comprehension of paleogeographical and temporal distribution of the titanosaur sauropods. Titanosaurs are common in Upper Cretaceous rocks of Brazil and Argentina. The age of the Rio Piranhas Formation is considered to range from Berriasian to early Hauterivian. Thus, the description of this new species opens new viewpoints concerning the paleobiogeographical aspects of these sauropod dinosaurs.

    Acanthurus albimento 
     Carpenter, Williams & Santos, 2017

      OceanScienceFoundation.org 

    Abstract

    Acanthurus albimento is described as a new surgeonfish from northeastern Luzon from six specimens collected during extensive fish-market surveys in the Philippines.The new species is characterized by a distinctive white band below the lower jaw; many irregular, wavy, thin, blue lines on the head; a brown-orange pectoral fin with a bluish tinge on the outer membrane of the rays and a dark band on the posterior margin; a narrow rust-orange stripe along the base of the dorsal fin; and a large blackish caudal spine and sheath with the socket broadly edged in black. An analysis using the mitochondrial cytochrome c oxidase subunit 1 (COI), supported by an independent multi-locus analysis, suggests phylogenetic affinities with an Acanthurus clade that includes A. auranticavusAbariene, A. blochii, A. dussumieri, A. gahhm, A. leucocheilus, A. maculiceps, A. mata, A. nigricauda, and A. xanthopterus; a clade that shares a suite of color characteristics. Based on the sampling history in the region, the new species may be a limited-range endemic in the westernmost Pacific Ocean, which is unusual for members of this genus. This raises potential questions about drivers of dispersal and long-held assumptions about zoogeographic patterns along the Kuroshio Current.

    Seiter & Wolff. 2017 


    Abstract

    Here Stygophrynus orientalis sp. nov. is described, a new charontid whip spider from Banggai Island, Indonesia, representing the most eastern record of the genus exceeding the formerly postulated restriction of its distribution western of the Wallace Line. In addition, the third known spermatophore of a Stygophrynus species is presented, which differs remarkably from those previously described from the genus. Finally, the cerotegument structure of the new species is depicted and compared with that of other Charontidae and Charinidae.

    Douzhanopterus zhengi 
    Wang, Jiang, Zhang, Cheng, Yu, Li, Wei & Wang, 2017

    DOI: 10.1038/srep42763 

    Abstract
    Pterosaurs are extinct flying reptiles, the first vertebrates to achieve powered flight. Our understanding of the evolutionary transition between basal, predominantly long-tailed forms to derived short-tailed pterodactyloids remained poor until the discovery of Wukongopterus and Darwinopterus in western Liaoning, China. In this paper we report on a new genus and species, Douzhanopterus zhengi, that has a reduced tail, 173% the length of the humerus, and a reduced fifth pedal digit, whose first phalange is ca. 20% the length of metatarsal III, both unique characters to Monofenestra. The morphological comparisons and phylogenetic analysis presented in this paper demonstrate that Douzhanopterus is the sister group to the ‘Painten pro-pterodactyloid’ and the Pterodactyloidea, reducing the evolutionary gap between long- and short-tailed pterosaurs.

     Bauer, Kunya, Sumontha, Niyomwan, Pauwels, Chanhome & Kunya, 2010

    Abstract

    A new cave-dwelling species of Cyrtodactylus is described from Chiang Mai Province in northern Thailand. Cyrtodactylus dumnuii sp. nov. may be distinguished from all other congeners by the possession of a series of enlarged femoral scales, disjunct precloacal and femoral pores in males (minute precloacal pores variably present in females), a relatively high number (18–22) of closely spaced, regularly arranged dorsal tubercle rows, well-defined non-denticulate ventrolateral folds, transversely enlarged subcaudal plates, and a color pattern of approximately six pairs of alternating light and dark transverse bands on the trunk. It is the nineteenth member of the genus recorded from Thailand and the eighth Thai Cyrtodactylus known to be a facultative troglophile.

    Syngnathus chihiroe 
    Matsunuma, 2017  

    Abstract

    A new species of pipefish, Syngnathus chihiroe sp. nov., (Syngnathidae), is described on the basis of a single specimen collected off Yakushima Island (East China Sea), southern Japan in a depth of 160–162 m. The new species is readily distinguished from all congeners by the combination of the following characters: dorsal-fin rays 38, pectoral-fin rays 17, trunk rings 18, tail rings 40, subdorsal rings 3.25 + 10.0 = 13.25, head length 8.7 in standard length, snout length 2.3 in head length and snout depth 3.7 in snout length. The new species is similar to Syngnathus schlegeli Kaup 1853, the only other northwestern Pacific Ocean congener, characterized by dorsal-fin rays 30–47, trunk rings 18–20 and tail rings 38–46. However, it differs from S. schlegeli in having a greater number of pectoral-fin rays (17 in the former vs. 11–15 in the latter), and a short deep snout (snout length 2.3 in head length and snout depth 3.7 in snout length vs. 1.6–2.0 and 5.6–11.3, respectively).

    Keywords: Pisces, East China Sea, southern Japan, Kagoshima Prefecture, Syngnathidae, new species, taxonomy



    Distribution: The species is currently known only from the type locality, southwest of Yakushima Island, Kagoshima Prefecture, Japan (East China Sea), in a depth of 160–162 m (Fig. 3).

    Etymology: The specific name, chihiroe, is derived from Japanese “chihiro”, meaning great depth, alluding to the depth of capture of the holotype and only known specimen (160–162 m), one of the deepest recorded for any member of the genus (Table 4).

    Xingxiulong chengi 
    Wang, You & Wang, 2017 

       DOI: 10.1038/srep41881 

    Abstract
    The Lufeng Formation in Lufeng Basin of Yunnan Province, southwestern China preserves one of the richest terrestrial Lower Jurassic vertebrate faunas globally, especially for its basal sauropodomorphs, such as Lufengosaurus and Yunnanosaurus. Here we report a new taxon, Xingxiulong chengi gen. et sp. nov. represented by three partial skeletons with overlapping elements. Xingxiulong possesses a number of autapomorphies, such as transversely expanded plate-like summit on top of the neural spine of posterior dorsal vertebrae, four sacral vertebrae, robust scapula, and elongated pubic plate approximately 40% of the total length of the pubis. Phylogenetic analysis resolves Xingxiulong as a basal member of Sauropodiformes, and together with another two Lufeng basal sauropodiforms Jingshanosaurus and Yunnanosaurus, they represent the basalmost lineages of this clade, indicating its Asian origin. Although being relatively primitive, Xingxiulong displays some derived features normally occurred in advanced sauropodiforms including sauropods, such as a four sacral-sacrum, a robust scapula, and a pubis with elongated pubic plate. The discovery of Xingxiulong increases the diversity of basal sauropodomorphs from the Lufeng Formation and indicates a more complicated scenario in the early evolution of sauropodiforms.

    Xingxiulong chengi gen. et sp. nov.


    Type locality and horizon: The specimens were excavated near Sankeshu (Three Trees) Village, Jinshan Town, Lufeng County, Chuxiong Yi Autonomous Prefecture, Yunnan Province, southwestern China (Fig. 1). The specimens were from the base of the Shawan Member of the Lower Jurassic Lufeng Formation, composed of dark purple silty mudstones.

    Etymology: The generic name “Xingxiu”, meaning constellation in Chinese, is derived from the name of the ancient “Xingxiu Bridge” in Lufeng County, which was built during the Ming Dynasty (1368–1644). The specific name is dedicated to Prof. Zheng-Wu Cheng (1931–2015), for his lifetime contribution to Chinese terrestrial biostratigraphy, including the Lufeng Basin.

    Diagnosis: A medium-sized basal sauropodiform with the following unique combination of character states (autapomorphies are marked by *): both surangular and angular extended more anteriorly with respect to the external mandibular fenestra; transversely expanded plate-like summit on top of posterior dorsal vertebrae* (convergent in basal saurischians); four sacral vertebrae, with two primordial sacrals bounded by a dorsosacral and a caudosacral* (convergent in derived sauropodiforms); robust scapula with both ends extremely expanded; ilium with ventral margin of postacetabular process strongly concave*; pubis with elongated proximal pubic plate relative to the pubic apron, with pubic plate approximately 40% of the total length of the pubis*(convergent in basal sauropods); posterolateral process of distal tibia much narrower anteroposteriorly and extended more laterally and distally than anterolateral process*; a median bulge present on the dorsoposterior margin of the astragalus; metatarsal V with strongly expanded proximal end with a proportion of proximal width/total length 0.85*.

    Neoclita pringlei 
    Perissinotto, 2017 


    Abstract

    A new genus is erected within the Cetoniini to describe a newly discovered species with characters shared between Heteroclita Burmeister, 1842Ichnestoma Gory & Percheron, 1833 and Meridioclita Krikken, 1982. Neoclita pringlei gen. et sp. nov. exhibits a simple clypeal structure without specialized armour, along with hypertrophic and hairy tarsal segments as well as a fully winged female. The new species also exhibits an aedeagal structure closest to Meridioclita, with dorsal lobes of parameres substantially narrower than the ventral ones. The species appears to be restricted to high altitudes in the southwestern peri-Drakensberg area of the Eastern Cape Province, South Africa. Similarly to other mountain relicts known from the southern African region, adults emerge only after major rainfall events during the late spring to early summer season and do not show any evidence of feeding. It appears that flying activity may be temporarily interrupted following soil desiccation, to resume promptly after the next rainfall.

    Tribe Cetoniini Leach, 1815

    Genus Neoclita gen. nov.

    Etymology: The name of the new genus arises from the latest discovery of another taxon in the “clita” grouping

    Neoclitapringlei gen. et sp. nov.  

    Etymology: The species is named after the renowned South African lepidopterologist Ernest Pringle, who first collected the new species in the Matatiele Nature Reserve and promptly brought it to my attention.

     Parotocinclus fluminense
    Roxo, Melo, Silva & Oliveira, 2017


    Abstract

    A new species of Parotocinclus is described from tributaries of rio São João, an Atlantic coastal river of Rio de Janeiro, southeastern Brazil. The new species is distinguished from its congeners by the possession of a triangular patch of dark pigmentation on the anterior portion of the dorsal-fin base, a fully developed adipose fin, complete exposure of the ventral surface of the pectoral girdle, and a distinctive pigmentation pattern of the caudal fin. The caudal fin has a hyaline background with a large black blotch covering its anterior portion, tapering irregularly through distal portions of the ventral lobe with a hyaline rounded area, and a small patch of dark pigmentation on distal portions of the dorsal lobe.
