A new species of Murina of the suilla-type is described from the Hkakabo Razi Landscape, Kachin, Upper Myanmar, an area that is currently being nominated as a World Heritage Site. The new species is a small vespertilionid, with a forearm length of 29.6 mm, and is very similar to M. kontumensis, which was recently described from Vietnam. However, it is distinguishable by a combination of external and craniodental morphology and genetics. The DNA Barcode reveals that the new species clusters sisterly to M. kontumensis but with a genetic distance of 11.5%. A single known specimen of the new species was collected from a lowland forest area in the plains of the Hkakabo Razi landscape, south-eastern Himalaya. Additional information on ecology, echolocation, and conservation are included. The high cryptic diversity of the genus Murina in Southeast Asia, as well as the Hkakabo Razi Landscape being a bat diversity hotspot, is highlighted.

Murina hkakaboraziensis sp. nov. 

Etymology. The species is named after the Hkakabo Razi Landscape, where the only known specimen was collected. The proposed English name is ‘Hkakabo Razi Tube-nosed Bat

Ecology and distribution. The new species, M. hkakaboraziensis sp. nov., was collected in a mist net set at the edge of a lowland semi-evergreen forest at the transition zone to an open space grassland, which undergoes an annual burn (Fig. 5). The new species was the only bat captured in the mist net. However, on the same night, four other insectivorous bats, Rhinolophus affinis, R. pusillus, Aselliscus stoliczkanus and Hipposideros pomona were captured in nearby mist nets and harp traps. Four other vespertilionids, M. cyclotis, M. feae, M. cf. eleryi, Kerivoula hardwickii, and K. furva were also captured in the same area on other nights. Currently, the new species is only known from the holotype collected from the type locality in the Hkakabo Razi Landscape, Kachin, northern Myanmar.

The discovery of Murina hkakaboraziensis sp. nov., as well as a recently described Kerivoula furva (Kuo et al. 2017), indicates that the Hkakabo Razi Landscape is extremely understudied in terms of bats. Based only on a single scientific expedition in 2016, 37 species of bats were recorded from HRL (P. Soisook, unpublished data) representing approximately 40% of bats in Myanmar. Nevertheless, the 2016 expedition focused only on a limited geographical area and elevation of the HRL. Future surveys to cover the variety of habitats, particularly at the higher elevations, would be of interest. 

The vespertilionid community in the HRL appears to be a geographical connection and a unique mix of species those found widespread in the Indochinese Region (e.g. M. cyclotis, M. feae, M. cf. eleryi, K. kachinensis, K. hardwickii, and K. furva), and those from the Indian Region (e.g. M. cf. jaintiana, M. cf. pluvialis). It indicates the importance of primary forests, and ongoing biogeographical processes of the HRL, underlining the significance of Myanmar’s endeavour to nominate the area as a Natural World Heritage Site.

Gorongosa Flat Gecko || DOI: 10.11646/zootaxa.4324.1.8 



A new species of flat gecko, Afroedura gorongosa sp. nov., is described from Gorongosa National Park, Sofala Province, central Mozambique. The new species is morphologically similar to A. transvaalica and A. loveridgei, from both of which it is genetically distinct (15–17% divergence; 400 bp of 16S rRNA). Morphologically it can be distinguished from both species by having fewer midbody scale rows (97–101) and a higher number of precloacal pores in males (8–13). The type series was collected on the western flanks of Mount Gorongosa (900 and 1100 m a.s.l.) in comparatively cool and moist microclimates, where it is threatened by illegal deforestation. Additional material was collected as low as 212 m a.s.l. on an inselberg near Mount Gorongosa. The new discovery adds to the growing number of endemic montane reptiles discovered in Mozambique in recent years, and highlights the need for a national conservation assessment of the country’s herpetofauna and continued protection of the Mount Gorongosa region.

Afroedura gorongosa sp. nov.

Etymology. The specific name refers to Mount Gorongosa and Gorongosa National Park in Central Mozambique, to which the species is endemic. We suggest Gorongosa Flat Gecko is a suitable common name. Afroedura, based on Oedura, is feminine and the specific epithet is treated as a noun in apposition.

Resumo: Aqui descreve-se uma nova espécie de osga, Afroedura gorongosa sp. nov., do Parque Nacional da Gorongosa, na Provín-cia de Sofala, centro de Moçambique. Do ponto de vista morfológico, a nova espécie assemelha-se às osgas A. transvaa-lica e A. loveridgei, sendo geneticamente distinta de ambas (divergência de 15–17%; 400 bp de 16S rRNA). Distingue-se morfologicamente de ambas as espécies por ter um número inferior de fileiras de escamas na secção mediana (97–101) e um número superior de poros pré-cloacal nos machos (8–13). A série-tipo foi recolhida nos flancos ocidentais da Serra da Gorongosa (900 e 1100 m a.s.l.), em microclimas relativamente mais frios e húmidos, onde se encontra ameaçada pela desflorestação ilegal. Estas osgas foram também recolhidas à altitude de 212 m a.s.l., num inselberg e próximo da Serra da Gorongosa. A nova descoberta junta-se ao crescente número de répteis endémicos de montanha descobertos em Moçambique nos últimos anos, e realça a necessidade de uma avaliação da conservação da herpetofauna do país a nível nacional, bem como a proteção da região do Monte Gorongosa.

[Herpetology • 2017] A Multilocus Phylogeny of the Genus Sarcohyla (Anura: Hylidae), and An Investigation of Species Boundaries Using Statistical Species Delimitation

  DOI: 10.1016/j.ympev.2017.09.010  

• We present a phylogenetic analysis of 17 species of the genus Sarcohyla using data from two mitochondrial (ND1 and 12s) and three nuclear genes (Rag-1, Rhod, and POMc).
• The widely distributed species S. bistincta is a complex of at least three species.
• Two undescribed species exists in the group.
• The species S. ephemera is a junior synonym of S. calthula.

The genus Sarcohyla is composed by 24 species endemic to México. Despite the large number of phylogenetic studies focusing on the family Hylidae, the relationships among the species of Sarcohyla are still poorly known, and the scarce numbers of specimens and tissue samples available for some of the species has hampered an appropriate phylogenetic analysis. We present the most comprehensive molecular phylogenetic study of Sarcohyla to date. We included 17 species of the genus Sarcohyla using data from two mitochondrial (ND1 and 12S) and three nuclear genes (Rag-1, Rhod, and POMc). We performed phylogenetic analyses using Bayesian inference, and the absence of conflicts with strong support between the separate gene trees indicates that incomplete lineage sorting and/or introgressive hybridization are negligible. A coalescent-based species-tree analysis of the four independent loci (three nuclear genes + mtDNA) mostly supports the same species-level relationships as the analysis of the concatenated data. By including new samples from additional species and localities, we find that: (1) the widely distributed species S. bistincta is a complex of at least three species, (2) another undescribed species exists in the group, (3) the species S. ephemera is not valid and it corresponds to a junior synonym of S. calthula. In addition, we conducted marginal likelihood estimation and used Bayes factors to test alternative species delimitation models for S. bistincta, the most widespread nominal species in the group. Our findings support three independent lineages of S. bistincta group, which are paraphyletic with respect to S. pentheter and S. calthula.

Keywords: Systematics, Molecular phylogeny, Hylidae, Sarcohyla, Mexico

Our analysis revealed several taxonomic problems in Sarcohyla. Of the 17 species included in the analysis, three species may represent junior synonyms of other taxa (S. arborescandensSephemera, and S. miahuatlanensis), and another two appear to represent multiple species (S. bistincta and S. thorectes). These problems may be explained, at least in part, by the absence of morphological autapomorphies in many species of Sarcohyla (which can therefore only be distinguished by unique combinations of traits), and to the scarcity of informative characters and high levels of homoplasy in the group (Duellman, 2001). Although external morphology usually is the first evidence for species recognition, molecular evidence and implementation of modern species delimitation methods based on coalescence theory are needed to identify/corroborate species (i.e., Grummer et al., 2014). Accurate species delimitation and phylogeny reconstruction in Sarcohyla is important to infer the historical biogeography of the highlands of Mexico and specially to develop accurate conservation plans for this group of frogs. For instance, underestimation of species diversity can impact the selection of the areas that will be conserved. Further fieldwork is needed to obtain the samples for a complete, fully resolved, well-supported phylogeny for the genus.

[Botany • 2017] Asplenium minutifolium (Aspleniaceae) • A New Species from Thailand

Asplenium minutifolium Kanem. & Tagane


A new species of Asplenium (Aspleniaceae), Asplenium minutifolium Kanem. & Tagane, from Phu Kradueng National Park, Loei Province, Northeast Thailand and Khao Yai National Park, Nakhon Nayok Province, Central Thailand, is described and illustrated. This species can be distinguished from all similar species in East and South-East Asia by its simple and small lamina (1–5 × 0.3–0.7 cm), small and entire pinnae (1–4 × 0.8–2.5 mm), reflexed pinna arrangement (>90° from the midrib) in the lower 2/3 of the lamina and a sori arrangement that is almost always arranged in a single row on the basiscopic vein. 

KEYWORDS: Asplenium, Aspleniaceae, Pteridophyte, Fern, new species, Phu Kradueng National Park, Khao Yai National Park, Thailand.

Asplenium minutifolium Kanem. & Tagane, sp. nov. 

Similar to Asplenium kiangsuense Ching & Y.X.Jing of southern China in size and shape of lamina, but differs in having a narrower lamina (ca 0.7 cm wide in A. minutifolium vs. ca 1 cm wide in A. kiangsuense), wingless rachis (vs. 2 slightly raised lateral wings), smaller pinnae (1–4 × 0.8–2.5 mm vs. 4–5 × 4–5 mm), generally fewer sori per pinna (1– 3(–4) vs. 3–5), and in the sori arrangement (usually arranged in a row vs. arranged oppositely). Also similar to Asplenium siamense Tagawa & K.Iwats. of North-East Thailand, but can be distinguished by its simple pinnae at the tip of lamina (vs. lamina forked several times at the tip), thicker pinnae (thickly papery vs. thinly papery), reflexed pinna arrangement in lower part (vs. divaricate around lamina), and pinnae with entire or slightly undulate margins (vs. shallowly lobed (lobes to ca 1mm long)).

Distribution.–– Currently Asplenium minutifolium is known only from Phu Kradueng National Park and Khao Yai National Park. 

Ecology.–– In Phu Kradueng National Park, Asplenium minutifolium occurs in a semi-shaded and damp rock crevice that is ca 50 cm wide and 10 cm deep, on the plateau at an altitude of ca 1300 m. Associated fern and lycophyte species include Aglaomorpha rigidula (Sw.) Hovenkamp & S.Linds., Goniophlebium subauriculatum (Blume) C.Presl, Oleandra undulata (Willd.) Ching, Pyrrosia lingua (Thunb.) Farw. var. heteractis (Mett. ex Kuhn) Hovenkamp, and Selaginella siamensis Hieron. Other than the elevation, nothing is known about the ecology of this species at Khao Yai National Park. 

Etymology.–– The species epithet “minutifolium” refers to the very small lamina and pinnae of this species.

[Entomology • 2017] Themira lohmanusHidden in the Urban Parks of New York City: A New Species of Themira (Sepsidae, Diptera) Described Based on Morphology, DNA Sequences, Mating Behavior, and Reproductive Isolation

 Themira lohmanus   Ang, 2017

New species from well-studied taxa such as Sepsidae (Diptera) are rarely described from localities that have been extensively explored and one may think that New York City belongs to this category. Yet, a new species of Themira (Diptera: Sepsidae) was recently discovered which is currently only known to reside in two of New York City’s largest urban parks. Finding a new species of Themira in these parks was all the more surprising because the genus was revised in 1998 and is not particularly species-rich (13 species). Its status is confirmed as a new species based on morphology, DNA sequences, and reproductive isolation tests with a closely related species, and is described as Themira lohmanus Ang, sp. n. The species breeds on waterfowl dung and it is hypothesized that this makes the species rare in natural environments. However, it thrives in urban parks where the public feeds ducks and geese. The mating behavior of Themira lohmanus was recorded and is similar to the behavior of its closest relative T. biloba.

Themira lohmanus Ang, sp. n.

Diagnosis:  Themira lohmanus is a relatively large, robust-looking sepsid species that resembles T. biloba. However, adult T. lohmanus males can be readily differentiated from the latter by their uniquely shaped, asymmetrical surstyli, which is symmetrical in T. biloba (Fig. 1A, see Morphological analysis section). While females of these two species do not have distinct structural differences, they can potentially be distinguished based on the color of the sclerous cuticle: in T. biloba, it tends to be glossy black while T. lohmanus tends to have a cupreous tinge. However, these characters may not be easily differentiated in faded specimens.

Etymology:  The new species is named after David J. Lohman, for his generous contributions of specimens to sepsid taxonomy.

Distribution: Nearctic. Thus far only found in New York City (Central Park and Prospect Park); likely to be found in more localities in the future, especially where waterfowl congregate.

[Crustacea • 2017] Two New Records of the Coral Symbiont Crab Genus Quadrella Dana, 1851 (Brachyura: Trapeziidae), from Taiwan, with Notes on the Taxonomy of Q. boopsis Alcock, 1898

 Qudrella boopsis  Alcock, 1898


Two symbiotic trapeziid crabs of the genus Qudrella Dana, 1851, were collected from southwestern Taiwan. Both are new records for the island. Quadrella coronata Dana, 1852, is usually associated with the soft coral Chironephthya spp., while Q. boopsis Alcock, 1898, was found with the scleractinian coral Tubastraea micrantha. The taxonomy of Q. boopsis is treated and the variation in the dorsal surface of the carapace, armature of the anterolateral margin and colour pattern discussed.

[PaleoMammalogy • 2017] Inticetus vertizi • A New Odontocete (Toothed Cetacean) from the Early Miocene of Peru Expands the Morphological Disparity of Extinct Heterodont Dolphins

Inticetus vertizi
Lambert, de Muizon, Malinverno, Celma, Urbina & Bianucci, 2017

A key step in the evolutionary history of Odontoceti (echolocating toothed cetaceans) is the transition from the ancestral heterodont condition – characterized by the presence of double-rooted cheek teeth bearing accessory denticles – to the homodont dentition displayed by most extant odontocete species. During the last few decades, new finds and the reassessment of specimens in collections revealed an increased morphological disparity amongst the Oligo–Miocene heterodont odontocetes. Based on a partly articulated skeleton from late Early Miocene (Burdigalian, 18.8–18.0 Ma) beds of the Chilcatay Formation (Pisco Basin, Peru), we describe a new genus and species of heterodont odontocete, Inticetus vertizi, in the new family Inticetidae. This large dolphin is characterized by, amongst other things, a long and robust rostrum bearing at least 18 teeth per quadrant; the absence of procumbent anterior teeth; many large, broad-based accessory denticles in double-rooted posterior cheek teeth; a reduced ornament of dental crowns; the styliform process of the jugal being markedly robust; a large fovea epitubaria on the periotic, with a correspondingly voluminous accessory ossicle of the tympanic bulla; and a shortened tuberculum of the malleus. Phylogenetic analyses (with and without molecular constraint; with and without down-weighting of homoplastic characters) yielded contrasting results, with Inticetus falling either as a stem Odontoceti or as an early branching member of a large Platanistoidea clade. With its large size, robust rostrum and unusual dental morphology, and the absence of conspicuous tooth wear, Inticetus increases the morphological and ecological disparity of Late Oligocene–Early Miocene heterodont odontocetes. Finally, this new taxon calls for caution when attempting to identify isolated cetacean cheek teeth, even at the suborder level.

[Mammalogy • 2017] Uromys vika • A New Species of Giant Rat (Muridae, Uromys) from Vangunu, Solomon Islands

Uromys vika Lavery & Judge, 2017

We describe the first new rodent species from Solomon Islands in more than 80 years. This new giant rat is known from a single specimen captured in a commercially felled Dillenia salomonensis tree on Vangunu Island. Morphologically, it closely resembles a fascinating secondary radiation of 3 species of Uromys (Cyromys) that are endemic to Guadalcanal Island. The cranium can be readily distinguished from those of other species of Uromys by its shorter maxillary tooth row, and shorter incisive foramina. The existence of this species has been suspected for over 2 decades. It is rare and cryptic, and conservation status is Critically Endangered due to its small distributional range, apparent low population densities, and rapid progress of commercial logging on Vangunu Island. Further surveys to locate additional animals and support for community led conservation initiatives on Vangunu are urgently needed to safeguard the species.

A new anurognathid pterosaurVesperopterylus lamadongensis gen. et sp. nov., is erected based on a complete skeleton with a skull preserved. It is characterized by two short distinct ridges present on the ventral surface of the cervical vertebrae; coracoids slightly longer than scapula; humerus, wing phalanx 3 and tibia nearly the same in length; grooves clearly present on the posterior surface of the wing phalanges 1–3; and the first toe reversed. It is the first anurognathid pterosaur from China with a definitively short tail, and the first pterosaur with a reversed first toe. The reversed first toe of Vesperopterylus indicates that it had arboreal habitats. The discovery of Vesperopterylus lamadongensis from the Jiufotang Formation strongly expands the geological age range for anurognathid pterosaurs.

Vesperopterylus is the first anurognathid pterosaur from China preserved with a clearly reduced tail, and it is also the youngest anurognathid pterosaur in geological age. The reversed first toe of Vesperopterylus may indicate that it, perhaps, has a gripping adaptation.

[Ichthyology • 2017] Astyanax taurorum • A New Species (Characiformes: Characidae) from dos Touros River, Pelotas River Drainage, An Upland southern Brazilian River

Astyanax taurorum 
 de Lucena, Zaluski & de Lucena, 2017 

A new species of Astyanax belonging to the Astyanax scabripinnis complex is described from dos Touros River, tributary of the Pelotas River, Uruguay River basin. Astyanax taurorum sp. nov. is distinguished from other species of the Astyanax scabripinnis species complex by having two humeral spots, the first vertically elongated; teeth of inner row of premaxilla with three to five cusps; 2–3 (modes 2 or 3) maxillary teeth; 20–23 (mode 22) branched anal-fin rays; 13–15 (mode 14) gill rakers on lower branch of the first branchial arch; 20–23 (mode 21) total gill rakers in first branchial arch; 33–36 (mode 35) perforated lateral line scales. Astyanax taurorum sp. nov. is similar to Astyanax paris; nevertheless, it can be readily distinguished from it by having a smaller head depth (73.6-83.1% vs. 86.4–95.6%) and smaller interorbital width (24.1–28.0% vs. 30.8–32.8%). In addition, it differs from A. paris by the presence a posttemporal hook-shaped posterodorsal margin.

Astyanax taurorum sp. nov.

Etymology: The specific name taurorum, is derived from the Latin masculine noun taurus (second declension, meaning bull) inflected in the plural and genitive case. Therefore taurorum means “of the bulls” in reference to “rio dos Touros“ (= Portuguese, which means “river of the bulls”) the type locality.

Distribution and habitat: Astyanax taurorum sp. nov. is known from the dos Touros River drainage, tributary of Pelotas River, which in turn is a tributary of Uruguay River (Fig. 5). The Pelotas River drainage is located in the region named “Campos de Altitude do Planalto das Araucárias (= Araucaria Plateau in Bertaco et al. 2016)” or “Campos de Cima da Serra”, which has a high level of endemism of fishes (Malabarba et al. 2009, Bertaco et al. 2016: 430) and other groups of animals (for example: sponges, Ribeiro et. al. 2009; crustaceans, Bond-Buckup et al. 2009). The dos Touros River tributary, type locality of Astyanax taurorum sp. nov., has a low to medium flow, transparent waters with stones and rocks on the bottom and moderate emergent marginal vegetation (Fig. 6). Four characid species were caught along with Astyanax taurorum sp. nov.: Bryconamericus patriciae Silva, 2004, B. iheringi Boulenger, 1887, Cheirodon interruptus Jenyns, 1842, and Oligosarcus brevioris Menezes, 1987.
