Idiocnemis schorri  
 Gassmann, Richards & Polhemus, 2016  

  DOI:  10.11646/zootaxa.4171.3.5 


Idiocnemis schorri sp. nov. is described from the Hindenburg and Muller Ranges and the Kikori River Basin of southern Papua New Guinea. The new species differs from all congeners by, among other characters, a unique colour pattern on the thorax. Characters of males and females are illustrated and compared to those of similar species from the Idiocnemis bidentata group. The new species is found along small, shallow rainforest streams and is currently known only from the Trans-Fly Foreland and Papuan Gulf Foreland areas of endemism.

[Ichthyology • 2016] Puntius euspilurus • A New Fish Species (Cypriniformes: Cyprinidae) from Kerala, India

 Puntius euspilurus 
Plamoottil, 2016 

 Puntius euspilurus, a new fish species of the family Cyprinidae, is described from Wayanad of Kerala, India. It is distinguished from its congeners by the following combination of characters: body elongated, rounded and slender, barbels feeble and never reach orbit or nostrils; last simple dorsal fin ray feebly osseous and flexible, 23- 24 lateral line scales, 2½ scales between lateral line and ventral fin and elongated pectoral fin which reaches to ventral fin.

Keywords: Western Ghats, Taxonomy, Mananthavady River, Puntius nigronotus

Distribution: Currently known to occur only at its type locality in Kerala, India.

Etymology: The specific epithet ‘euspilurus’ is a Greek word, (eu- well; spilos- blot; urus- tail), referring to distinct black basal spot on caudal fin.

Puntius euspilurus is an edible freshwater fish residing in the water bodies of Wayanad. It may be a unique fish showing similarity with [Puntiusmahecola barbs. Elongated body with feebly osseous\ last simple dorsal ray separates this fish from other fishes of the family. It prefers rapidly flowing shallow and clear waters. According to local fishermen it appears in great numbers in paddy fields during the onset of southwest monsoon. The new species is said to occur only in unpolluted areas. Protection of water bodies is inevitable for the survival of the new species.

[Herpetology • 2016] A Revision and Key for the Tribe Diaphorolepidini (Serpentes: Dipsadidae) and Checklist for the Genus Synophis

Synophis niceforomariae  
Pyron, Arteaga, Echevarría, & Torres-Carvajal, 2016  

DOI:  10.11646/zootaxa.4171.2.4


The genus Synophis contains a number of enigmatic species, distributed primarily in the Andean highlands of northern South America. Their extreme crypsis and rarity has precluded detailed study of most species. A recent flurry of collection activity resulted in the accession of many new specimens, and the description of 4 new species in 2015, doubling the number of described taxa. However, lingering questions remain regarding the assignment of many new and historical specimens, the morphological limits and geographical ranges of the species, and their phylogenetic relationships. We analyze new and existing morphological and molecular data to produce a new molecular phylogeny and revised morphological descriptions. We validate the previously unavailable tribe name Diaphorolepidini Jenner, Pyron, Arteaga, Echevarría, & Torres-Carvajal tribe nov., describe a 9th species Synophis niceforomariae Pyron, Arteaga, Echevarría, & Torres-Carvajal sp. nov., and offer new Standard Names in English and Spanish for the group: Andean Shadow Snakes and Culebras Andinas de la Sombra, respectively. A variety of features such as vertebrae and hemipenes show an interesting range of variation in the group, which should be evaluated in future studies, to refine species limits and diagnoses further. Cryptic and undiscovered diversity undoubtedly remains, and we hope this summary provides a robust basis for future work.

Sanjay's Black-tip Pethia  |  DOI:  10.1111/jfb.12980 


Pethia sanjaymoluri, a new cyprinid, is described from the Pavana and Nira tributaries of Bhima River, Krishna drainage, Maharashtra, India. It can be distinguished from congeners by a combination of characteristics that includes an incomplete lateral line, absence of barbels, upper lip thick and fleshy, 23–25 lateral series scales, 7–12 lateral-line pored scales, 10 predorsal scales, 11–14 prepelvic scales, 17–20 pre-anal scales, 4½ scales between dorsal-fin origin and lateral line, four scales between lateral line and pelvic-fin origin, 8–15 pairs of serrae on distal half of dorsal-fin spine, 12–14 branched pectoral-fin rays, 4 + 26 total vertebrae, 4 + 5 predorsal vertebrae, 4 + 13 abdominal vertebrae, 13 caudal vertebrae and a unique colour pattern comprising a humeral spot positioned below the lateral line and encompassing the third and fourth lateral-line scales and one scale below, one caudal spot on 17th–21st lateral-line scales with a yellow hue on its anterior side and apical half of dorsal fin studded with melanophores making the fin tip appear black. Genetic analysis based on the mitochondrial cytochrome b gene sequence suggests that the species is distinct from other known species of Pethia for which data are available.

Keywords: barbel; freshwater cyprinid; Maharashtra; molecular phylogeny; osteology; taxonomy

[Herpetology • 2006] Laticauda frontalis (de Vis, 1905) and Laticauda saintgironsi n. sp. from Vanuatu and New Caledonia (Serpentes: Elapidae: Laticaudinae) — A New Lineage of Sea Kraits?

Laticauda saintgironsi 
Cogger & Heatwole, 2006



The sea krait Laticauda colubrina is the most widespread member of its genus, extending from the Bay of Bengal through much of Asia and the Indo-Malayan Archipelago to New Guinea and many islands of the western Pacific Ocean. Unconfirmed records of the species may extend the range to the western coast of Central America. The species is subject to marked geographic variation in a number of morphological and meristic characters that have to date defied finer taxonomic resolution. Two members of this complex previously subsumed under the specific name colubrina are here formally elevated to full species status. One species — Laticauda saintgironsi n.sp. — consists of those populations of L. colubrina s.l. found around the coast and in the coastal waters of the main island of New Caledonia. The second species — Laticauda frontalis (de Vis, 1905) — is a dwarf species found in sympatry and syntopy with Laticauda colubrina in Vanuatu and the Loyalty Islands of New Caledonia.

New Guinea is one of the centres of diversity of Benstonea (Pandanaceae), a genus distributed from India to Fiji. Ten species were previously recognised on this island and further field observations, accompanied by the study of available herbarium material have brought new insights into species delimitations within a group of caespitose species with a solitary terminal infructescence. The taxonomical identity of Benstonea odoardoi is elucidated and is considered here as a synonym of Benstonea lauterbachii. Three new combinations and a new name—based on names of Pandanus species previously treated as synonyms of Benstonea odoardoi—are proposed for four distinct species belonging to this group of caespitose species and restricted to Indonesian New Guinea and Papua New Guinea. Finally, Pandanus bintuniensis is here considered as a synonym of Benstonea permicron.

[Herpetology • 2016] Out of Borneo, Again and Again: Biogeography of the Stream Toad Genus Ansonia Stoliczka (Anura: Bufonidae) and the Discovery of the First Limestone Cave-dwelling Species, Ansonia khaochangensis, from southern Thailand

 Ansonia khaochangensis  
Grismer, Wood, Aowphol, Cota, Grismer, Murdoch, Aguilar & Grismer, 2016 

Cave-dwelling Stream-Toad | คางคกห้วยถ้ำ


Subsequent to the Miocene (approximately 35 Mya), Borneo has served as an insular refuge and a source of colonization for a broad range of species emigrating to others parts of Sundaland. A phylogeny-based historical biogeographical hypothesis for the Stream Toad genus Ansonia supports multiple instances of an out-of-Borneo scenario. An ancestral range estimation indicates that in situ speciation of Ansonia on the island of Borneo during the Late Miocene and Pliocene (approximately 2–13 Mya) eventually resulted in an invasion of the Philippines, Sumatra, and two independent invasions of the Thai-Malay Peninsula. When collecting material for the biogeographical analysis, a new species of Ansonia, Ansonia khaochangensis sp. nov. was discovered in a limestone cave from the Khao Chang karst tower in Phangnga Province, in southern Thailand. Ansonia khaochangensis sp. nov. can be differentiated from all other species of Ansonia by having a unique combination of morphological and colour pattern characteristics. Phylogenetic evidence based on the mitochondrial genes 12S and 16S indicates that it is nested within a clade of other species distributed north of the Isthmus of Kra. The cave lifestyle of this new species is a unique and a significant departure from lotic environments common to most other species of Ansonia. The reproductive biology of this species is unknown.

Ansonia khaochangensis sp. nov.
Cave-dwelling Stream-Toad

Diagnosis. Ansonia khaochangensis sp. nov. can be differentiated from all other species of Ansonia by the combination of the following characters: maximum SVL of 35.5 mm (34.0–35.3 mm) for females and 32.0 mm (31.9–32.0 mm) for males; snout projecting beyond lower jaw; tympanum visible; vocal sac opening on right; no white or yellow tubercle at rictus; no tuberculate, interorbital ridges; finger and toe tips rounded, bulbous but not forming discs; first finger not reaching disc of second; webbing formula on foot I 1, II ½–2, III 1½–2, IV 2–2, V 1; tarsal ridge present; inner and outer metatarsal tubercles present; submandibular tubercles absent; dorsal tubercles present but small, low, and rounded; no dorsolateral row of enlarged tubercles on sides or back; no oblique flap of skin on either side of vent; abdomen and gular region coarsely granular; iris black; no light spots on the gular region or abdomen; no suborbital or postorbital white markings; no light interscapular spot; no light crossbars on hind limbs, no light vertebral stripe. These character states are scored across all species of Ansonia in Table 4.


Distribution. Ansonia khaochangensis sp. nov. is known only from the type locality at Takua Pa District, Phang Nga Province, southern Thailand (Fig. 1).

Natural history. Ansonia khaochangensis sp. nov. is only known from the Khao Chang tower karst formation that rises precipitously to an elevation of 125 m and frames the northwest border of the city of Phang Nga (Fig. 6). Along the southeast face of the karst formation is the massive Phung Chang Cave that has a subterranean water system that runs beneath the karst tower. This southeast face is also riddled with several smaller caves. Approximately 0.5 km southwest of the mouth of Phung Chang Cave is a very small opening at the base of the karst tower that winds its way inward for approximately 20 m wherein we found A. khaochangensis sp. nov. (Fig. 6). During the day, specimens were found only within the recesses of the cave on the vertical cave walls as high as 3 m above the cave floor. To escape, toads were able to move sideways up the cave walls in an attempt to wedge themselves into narrow cracks near the celling. Toads were also observed in the cave at night but would venture out to climb on the outside of the karst tower. Some specimens were found as high as 10 m above the forest floor both on the karst and sitting on the leaves of small plants growing out of the karst. The distinctive, virtually monochromatic, brown coloration of this species appears to be a result of substrate matching in that frogs are reasonably well-camouflaged on the limestone substrate. We interpret this as an indication that this microhabitat is not something that is occasionally utilized and that this genus, which has a lotic life style elsewhere, has adapted to this microhabitat over a long period of time in that it split off from its sister lineage approximately 5.5 Mya (Fig. 3).

The reproductive biology of this species is completely unknown. Most other Ansonia require fast-moving lotic systems and all require water for tadpole development. We assume that there are other sources of underground water that these toads must be using for reproduction because there are no above-ground systems nearby that we could find. Fieldwork is currently being planned to investigate this species’ presumably unique reproductive biology.

Etymology. The specific epithet khaochangensis is in reference to the type locality of this species in the Khao Chang tower karst formation.

[Herpetology • 2016] Litoria bella • A New Species of Treefrog (Litoria) from Cape York Peninsula, Australia

Litoria bella 
McDonald, Rowley,  Richards & Frankham, 2016.


We describe a new species of treefrog from northern Australia. Litoria bella sp. nov. is morphologically and genetically most similar to frogs in the L. gracilenta and L. chloris groups but is distinguished from all members in these groups by a combination of a moderately large male body size (34.5–41.8 mm SVL), near-immaculate green dorsum, orange venter, bright orange digits and webbing, bluish purple lateral surfaces of the thighs, no pale canthal stripe, white bones, and a highly-pulsed, single-note, male advertisement call with a pulse rate of 56–64 pulses/s and dominant frequency of 2.6–2.8 kHz. Litoria bella sp. nov. has a patchy distribution across the Cape York Peninsula, inhabiting rainforest and monsoon vine thicket in close association with watercourses. The new species’ affinities lie with L. auae from southern New Guinea rather than with L. gracilenta from eastern Australia. Molecular data suggest that the L. gracilenta group should be expanded to include L. chloris and L. xanthomera, two moderately large green treefrogs from eastern Australia.

Keywords: Amphibia, Anura, treefrog, new species, Queensland

Etymology. The specific name “bella” (Latin), meaning pretty or lovely, is used as an adjective in reference to the beautiful coloration of this species.

Suggested common name. Cape York Graceful Treefrog.
