[Herpetology • 2017] On The Taxonomic Status of Eurylepis poonaensis (Squamata: Scincidae): Resolving A Long-standing Conundrum


Eurylepis poonaensis (Sharma, 1970) 

SALAMANDRA. 53(3) 

Abstract

 The scincid genus Eurylepis was split off from the cosmopolitan genus Eumeces sensu lato, with Eurylepis taeniolatus being the type species, which is taxonomically poorly understood. The other nominate species in this genus is Eurylepis poonaensis, which was known only from its type locality and original description, and is the only known member of the subfamily Scincinae from near the Western Ghats. However, earlier studies raised doubts about its specific validity, often without examining type or other specimens. We collected fresh samples of this species from the type locality and nearby areas. Based on the examination of the holotype and the new material, we provide a detailed redescription of E. poonaensis, additional data on its skeletal structure, habitat, and natural history. We also provide a detailed redescription of E. taeniolatus based on the holotype to avoid further taxonomic ambiguity. 

Key words. Taxonomic resolution, species redescription, Eurylepis taeniolatus, India.

[Botany • 2017] Argostemma cordatum • A New Species (Rubiaceae) from southern Vietnam


Argostemma cordatum Nuraliev


Abstract

Argostemma cordatum, a new species of Rubiaceae, is described and illustrated. The species was discovered in 2014 during a botanical survey of the Chu Yang Sin National Park (Dak Lak province, Southern Vietnam). Argostemma cordatum possesses a solitary large leaf per plant (along with one very small leaf). The new species differs from morphologically similar species mainly by the small size of the enlarged leaf and cordate base of the enlarged leaf. It is also characterized by the following features: plant completely glabrous, stipules minute and reduced to papillate warts, inflorescence with all axes elongated, anthers coherent into anther cone and dehiscent by longitudinal slits, style slightly exserted. An extended description of the vegetation in the area inhabited by A. cordatum is provided.

Giant sengis (Macroscelidea; Macroscelididae; Rhynchocyon), also known as giant elephant-shrews, are small-bodied mammals that range from central through eastern Africa. Previous research on giant sengi systematics has relied primarily on pelage color and geographic distribution. Because some species have complex phenotypic variation and large geographic ranges, we used molecular markers to evaluate the phylogeny and taxonomy of the genus, which currently includes four species: R. chrysopygus, R. cirnei (six subspecies), R. petersi (two subspecies), and R. udzungwensis. We extracted DNA from fresh and historical museum samples from all taxa except one R. cirnei subspecies, and we generated and analyzed approximately 4700 aligned nucleotides (2685 bases of mitochondrial DNA and 2019 bases of nuclear DNA) to reconstruct a molecular phylogeny. We genetically evaluate Rhynchocyon spp. sequences previously published on GenBank, propose that the captive R. petersi population in North American zoos is likely R. p. adersi, and suggest that hybridization among taxa is not widespread in Rhynchocyon. The DNA sample we have from the distinctive but undescribed giant sengi from the Boni forest of northern coastal Kenya is unexpectedly nearly identical to R. chrysopygus, which will require further study. Our analyses support the current morphology-based taxonomy, with each recognized species forming a monophyletic clade, but we propose elevating Rhynchocyon cirnei stuhlmanni to a full species [Rhynchocyon stuhlmanni].

[Ichthyology • 2017] Taxonomic Revision of the Seasonal Killifish Genus Nothobranchius (Cyprinodontoidei: Aplocheilidae) from Zanzibar, East Africa



ABSTRACT
Nothobranchius guentheri and Nothobranchius melanospilus, the two seasonal killifishes of the genus Nothobranchius occurring in Zanzibar Island, Tanzania, were involved in past taxonomical mistakes and are still misidentified in museum collections. A historical review is herein presented and both species are redescribed on the basis of type material and recent collections. Nothobranchius guentheri, a popular aquarium fish, is endemic to Zanzibar, and N. melanospilus, geographically widespread in East Africa, occurring both in Zanzibar and in continental river basins. These species are distinguished by a series of morphological features not previously reported in the literature, including pre-dorsal length and relative position of the anterior portion of the dorsal-fin skeletal support and vertebrae; number of gill-rakers of the first branchial arch, caudal-fin rays, scales of the longitudinal series, series of scales around caudal peduncle, and vertebrae; frontal squamation; and arrangement and number of neuromasts of the supraorbital series. The present taxonomic revision comprising N. guentheri and N. melanospilus, the oldest species names of the genus in the East African biodiversity hotspot, is important to improve the knowledge of the genus in a region where its taxonomy is still problematic

[Ichthyology • 2017] Parapercis binotata • A New Species of Parapercis (Teleostei: Pinguipedidae) from the Solomon Islands


Parapercis binotata Allen & Erdmann, 2017

Abstract

A new species of pinguipedid fish, Parapercis binotata, is described from the Solomon Islands on the basis of six adult specimens, 46.5–56.5.5 mm SL. The new taxon belongs to the Parapercis cylindrica complex, which contains five other western Pacific Ocean species: P. australis, P. cylindrica, P. haackei, P. lineopunctata, and P. snyderi. It is most similar to P. lineopunctata from the East Indian Archipelago, but adult males are clearly distinguished by the presence of two short black bands, one on the cheek and another on the lower pectoral fin. Although lacking these markings, females differ from those of P. lineopunctata by the presence of a curved black band below the eye. The only known habitat of the new species consists of a nearly enclosed lagoon in 4-8 m depth. Analyses of the mtDNA “barcode” marker COI sequences for the P. cylindrica species complex show exceptionally deep divergences between most species, about 15–20% divergence between all but one pair of species, with P. binotata 14.52% different from its nearest relative, P. lineopunctata.
  
Key words: taxonomy, systematics, ichthyology, coral-reef fishes, Indo-Pacific Ocean, sandperch, DNA barcoding.

Parapercis binotata, n. sp. 
Solomons Sandperch

Diagnosis. Dorsal-fin rays V,21; anal-fin rays I,16–17; pectoral-fin rays 14–16; lateral-line scales 46–48; four, progressively larger, recurved canine teeth on each side at front of lower jaw; scales on body ctenoid except cycloid on prepelvic area; opercle and cheek covered with ctenoid scales; body depth 4.7–5.5 in SL; caudal fin truncate to slightly rounded; pelvic fins reaching beyond anal-fin origin; color of head and body generally white, 7–8 short brown bars on back, above lateral line and lower side with corresponding narrow yellow-orange to brown bars; adult with conspicuous black band on rear edge of cheek and short black band on lower pectoral-fin rays; females with curved black band under eye along lower edge of suborbital; found on sand substrates in depths of less than 10 m.

Etymology. The species is named binotata (Latin: two markings), with reference to the diagnostic dark bands on the cheek and pectoral fins of males. It is treated as a feminine singular compound adjective.

Distribution and habitat. The new species is known only from the Solomon Islands type locality. The relatively unusual habitat consisted of a nearly enclosed, narrow, dead-end lagoon (Fig. 3) with a gradually sloping, white sand bottom with scattered, mainly low-profile, coral formations. The fish was common at depths between about 4–8 m, generally occurring as solitary individuals

[Herpetology • 2017] Thamnodynastes phoenix • A New Species of Thamnodynastes (Serpentes: Dipsadidae: Tachymenini) from the Open Areas of central and northeastern Brazil


Thamnodynastes phoenix
Franco, Trevine, Montingelli & Zaher, 2017 

SALAMANDRA. 53(3)

Abstract
 The genus Thamnodynastes Wagler, 1830 is currently composed by nineteen species of viviparous and opistoglyphous snakes, largely distributed in South America, from Colombia to Argentina. The analyses of a large data set of specimens from South American collections evidenced one unknown species from the open formations of central and northeastern Brazil, which is described here. The new species is distinguished from all its congeners by a unique combination of characters, including 19 dorsal rows of smooth scales on the midbody, the smallest number of subcaudals in the genus, and a distinct hemipenial morphology and coloration pattern. To define this new species we present robust diagnostic characters and discuss comparisons with other species of this diverse and taxonomically complex genus of Neotropical snakes. 

Key words. Neotropical region, Caatinga, Cerrado, Squamata, taxonomy, Xenodontinae.

Thamnodynastes sp. 2 – Coelho, Souza, Weider, Pereira & Ribeiro, 2013
Thamnodynastes sp. – Guedes, Nogueira & Sawaya, 2014

Diagnosis: Thamnodynastes phoenix sp. n. differs from all other species of the genus by the following combination of characters: 19/19/15 dorsal rows with smooth scales; maximum SVL 495 mm; maximum TL 136 mm; ventral scales 133 to 159; subcaudals 40 to 66; coloration of the ventral portion of the head extremely spotted with dark-brown dots, infralabials and chin shields with a white centre. Darkening intensifies on the infralabial borders, outlining a clear contrast of lateral and dark margins (Fig. 2). Two pairs of noncontinuous longitudinal dark ventral stripes, darker at the transition of the venter and the lateral sides, with a more conspicuous black spot on the apex of each ventral scale; tip of the tail lighter than the overall body coloration without blotches or dots, almost white in juvenile specimens.

Distribution: Thamnodynastes phoenix sp. n. occurs on open savannas of Brazil, predominantly the Caatinga formation of northeastern Brazil, in the states of Alagoas, Bahia, Ceará, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, and Sergipe, extending to the Caatinga enclaves of the region of Jaíba, Minas Gerais. It also encompasses the Cerrado in central Brazil, in the states of Goiás, Tocantins and Minas Gerais (Fig. 6).

 Natural History: The inspection of a few dissected specimens confirmed the viviparous reproductive mode of this species, as expected for members of the tribe Tachymenini. The specimen MZUSP 10462 (SVL 407 mm) exhibited eight well-developed embryos. The species is predominately terrestrial and nocturnal, feeds on frogs, and is associated with different types of Caatinga and Cerrado vegetation (Guedes et al. 2014).

Etymology: The specific epithet phoenix (Greek: φοῖνιξ phoinix; Latin: phoenix, phœnix, fenix) refers to the mythological bird that dies in combustion and subsequently rises from ashes in a cycle of life and death. This name acknowledges the fact that the previously selected holotype, used originally for the species description, was lost in the fire that consumed 90% of the Herpetological Collection “Alphonse Richard Hoge” of the Instituto Butantan, on March 15, 2010. Some specimens, including two paratypes, were rescued from the fire, and the data previously collected from the lost specimens were kept and used herein.

[Mammalogy • 2017] Nyctimene wrightae • A New Tube-nosed Fruit Bat (Pteropodidae: Chiroptera) from New Guinea, A Re-diagnosis of N. certans and N. cyclotis, and A Review of their Conservation Status


Nyctimene wrightae Irwin, 2017


Abstract
 The tube-nosed fruit bat genus Nyctimene comprises 18 species found in the Philippines, Wallacea, Melanesia and the Solomon Islands but species taxonomy has remained problematic. A review of the cyclotis group, consisting of N. cyclotis and N. certans from New Guinea is presented, using morphological and genetic data. Historically, the taxonomy of the cyclotis group has been severely impeded by the lack of illustrations or photographs of the majority of the types. This led authors to differ in their treatment of these species, suggesting that the distinct taxa N. cyclotis and N. certans might be conspecific. Here, N. cyclotis and N. certans are recognized as full species and are re-diagnosed. I describe Nyctimene wrightae sp. nov., a widespread New Guinean species which is tentatively placed in the cyclotis group. These three species and the sympatric N. a. papuanus, of similar body-size, are morphologically distinguished using discriminant function analyses and non-metric characters. An identification key is provided. Species distribution and conservation status are evaluated. The IUCN threat status recommended for each species is: N. wrightae sp. nov. Least Concern; N. certans (known from < 200 specimens) with unknown population size and trends, Data Deficient; and N. cyclotis, known from only two male specimens, Vulnerable. Further research is required on the basic ecology of all of these species, which remains virtually unknown.

Nyctimene wrightae sp. nov.

Etymology. With great pleasure I name this bat after Dr Debra Wright, Director for Wildlife Conservation Foundation, PNG 1996–2003, the co-founder of PNG Research Foundation and PNG Institute of Biological Research. She has tirelessly given her energy and considerable skills to capacity building and training Papuan New Guinean scientists. She provided logistic assistance for my team and I, helped me secure funding, provided access to facilities, and gave moral and intellectual support throughout my field-work. Her good humour, boundless energy, passion and generosity meant that despite spending many years together in remote places, we have formed a lifelong friendship. It was this cryptic bat species that started my whole journey with Nyctimene

Common name. Happy tube-nosed fruit bat. Field assistants Toby Kamli and Rafael Kaneg, noticed the difference between this species and N. a. papuanus in the hand and called this species the hamamas bat, which in Tok Pisin means the happy bat, due to the wide “smile” characteristic of this species. I therefore propose the happy tube-nosed fruit bat as the common name, alluding to the “smile” that seems to result from the broad dental arcade and palate and very short rostrum, which are diagnostic characters of the species.

[Gastropoda • 2017] Attenborougharion gen. nov. (Mollusca: Pulmonata: Helicarionidae): A Likely Case of Convergent Evolution in southeastern Tasmania


Attenborougharion rubicundus (Dartnall & Kershaw, 1978)

Hyman & Köhler, 2017  

Abstract
Helicarion Férussac, 1821 from southeastern Australia currently comprises five species of endemic semislugs. Analyses of comparative morphological data and partial sequences of the mitochondrial genes cytochrome c oxidase subunit I (COI) and 16S rRNA (16S) reveal that one of these species, Helicarion rubicundus Dartnall & Kershaw, 1978, which is restricted to southeastern Tasmania, is not closely related to the other known species of this genus. This species is distinguished from Helicarion in several key morphological characters, such as the bright two-toned red and green colouration of its larger body with a flattened tail that is keeled only at the tip, the triangular shape of the pneumostome, the degree and type of folding present in the spermoviduct and free oviduct, the presence of a longer, more slender bursa copulatrix, the presence of a small epiphallic caecum and a hooked flagellum, and the presence of irregular longitudinal pilasters in the penial interior in contrast to the v-shaped rows of papillose lamellae seen in Helicarion. Moreover, the mitochondrial phylogeny provides evidence that this species is phylogenetically distinct from Helicarion as well as any other currently described genus from southeastern Australia. Based on these findings, we here describe a new genusAttenborougharion, for this species.

Keywords: Helicarionoidea; morphology; mitochondrial DNA; land snail; taxonomy.

Helicarion rubicundus Dartnall & Kershaw, 1978: 2; Kershaw, 1980: 213.

Distribution and conservation status: Attenborougharion rubicundus is found only on the Tasman and Forestier Peninsulas in Tasmania (Taylor, 1991; Otley et al., 1999). The total known extent of occurrence of this species is 85 sq.km., leading to its listing as Vulnerable on the IUCN Red List of Threatened Species. In addition to its restricted range, within this area Attenborougharion rubicundus inhabits only closed wet forests and is not found in dry forests or damp sclerophyll forests (Otley eal., 1999), making it vulnerable to habitat loss through the effects of climate change as well as habitat destruction through changed land use.

[Ichthyology • 2017] Cordylancistrus pijao • A New Species of the Catfish Genus Cordylancistrus (Siluriformes, Loricariidae) from the Magdalena River, Tolima, Colombia


Cordylancistrus pijao
Provenzano & Villa-Navarro, 2017


Abstract

A new species of catfish is described from Colombia, and provisionally assigned to the genus Cordylancistrus. The new species is most similar to C. perijae and C. nephelion from Venezuela. The description is based on ten specimens collected from tributaries of the Magdalena River which drain the eastern slope of the Cordillera Central and the western slope of Cordillera Oriental, in the Department of Tolima. The new species is the first Cordylancistrus described from the Magdalena River basin. With this discovery, the number of Cordylancistrus species in Colombia increases to three. The geographic distribution of the species suggest that Andean orogenesis played an important role in the diversification of the group.

[Herpetology • 2017] Plectrohyla calvata • A New Species of Hylid Frog of the Genus Plectrohyla (Anura: Hylidae: Hylinae) from southwestern Honduras: Montaña de Celaque Honduran Frogs previously Referred to as Plectrohyla guatemalensis


Plectrohyla calvata McCranie, 2017


Abstract
 I describe a new species of hylid frog of the genus Plectrohyla from the isolated Montaña de Celaque in southwestern Honduras, which previously was referred to as P. guatemalensis. The new species differs from P. guatemalensis by the presence of yellowish olive-green dorsal surfaces that lack distinct darker dorsal markings in both sexes, mostly smooth dorsal surfaces in adult males and a tendency for less tuberculate dorsal surfaces in adult females, a smaller prepollex in males, a tendency for smooth midventral surfaces in adult males, and both sexes reaching a smaller adult size. This description brings the total number of recognized species of Plectrohyla to 19.

 Key Words: Cloud forest, isolated population, new species, Spike-thumbed Hylid, southwestern Honduras

Resumen: Describo una nueva especie de rana arborícola del genero Plectrohyla de la aislada Montaña de Celaque en el suroeste de Honduras, que anteriormente se había referido como P. guatemalensis. La nueva especie se difiere de P. guatemalensis por la presencia de una coloración amarillenta verde-oliva en las regiones dorsales que también carecen de marcas más oscuras en ambos sexos, con las superficies dorsales mayormente lisa en machos adultos y una tendencia hacia una reducción de tubérculos en las superficies dorsales en hembras adultas, un prepollex más pequeño en machos, una tendencia hacia tener las superficies midventrales más lisas en machos adultos, y en ambos sexos alcanzando un tamaño adulto más pequeño. Esta descripción lleva el número total de especies reconocidas de Plectrohyla a 19.
