A new species of the soft-shelled turtle genus Pelodiscus is described based on seven specimens from Huangshan, southern Anhui Province, China. The new species, Pelodiscus huangshanensis sp. nov., is distinguished from other species in the genus Pelodiscus by the following characteristics: (1) Small size (maximum carapace length of 101.16 mm and maximum body length of 190 mm); (2) keel high; (3) tiny yellowish-white spots on the throat; (4) no black pinstripes around the eyes; (5) white longitudinal bands on both sides of the neck in juveniles, absent in adults; (6) plastron yellowish-white, and only a dark patch on each side of the armpit; (7) many tubercles on the dorsal surface, but indistinct in the center; and (8) entoplastron “⌒” shaped. The phylogenetic relationships of the species in Pelodiscus were reconstructed using the sequences of cytochrome b (cyt b) and NADH dehydrogenase subunit 4 (ND4) genes. The new species formed a monophyletic clade with strong support. The uncorrected pairwise distances between the new species and other representatives of Pelodiscus ranged from 5.4% to 9.2% for cyt b and 4.1% to 7.6% for ND4. The new species brings the number of species of the genus Pelodiscus to six; five species are distributed in China, with three species endemic to China.

A New Species

The genus Psyllaphorura is reported from China for the first time. A new species, Psyllaphorura jiangsuensis sp. n. as the eighth species of the genus, is described from Nanjing, Southeast China. It is most similar to the Russian species Psyllaphorura martynovae (Stebaeva, 1985) in many respects. However, it can be distinguished from the latter by number of vesicles in the postantennal organ, number of setae on ventral tube, length ratio of unguiculus to unguis, absence of unguiculus basal lamella and maximum body length. A key to all of the species of Psyllaphorura is provided.

We describe the new species Amolops mengdingensis sp. nov. from southwestern Yunnan, China. It belongs to the Amolops monticola species group and phylogenetically clusters together with Amolops akhaorum and Amolops archotaphus with strong support, although the relationships between these three species are not resolved. Distance between the new species and A. akhaorum is 4.7% and distance between the new species and A. archotaphus is 5.2% for 16S rRNA sequences. The new species is characterized by the following characters: distinct dorsolateral folds; side of the head dark brown with a white upper lip stripe extending to the axilla; dorsal surface smooth, except white spinules on posterior part of dorsolateral folds and above vent; top of head and dorsum green with dark spots in life; loreal region dark brown and flanks brown without any coloration of green; SVL 36.9–40.2 mm in males and 64.3 mm in female; two external subgular vocal sacs in males; vomerine teeth in two oblique ridges, separated by a small distance; pineal body absent; snout longer than eye diameter; internarial space broader than interorbital space; tympanum distinct, smaller than half of eye diameter; all fingertips expanded; two palmar tubercles; outer metatarsal tubercle absent; tibiotarsal articulation reaching beyond snout tip; near immaculate venter; limbs dorsally grayish brown with clear dark brown bars on hindlimbs; and velvety nuptial pads.

A new species Spiochaetopterus nonatoi is described from the south-eastern coast of Brazil, the type locality being Flamengo Bight, 6-m depth (23°30′S 45°06′W). This species is distinguishable from already erected species of the same genus by the following characteristics: oculate specimens of large size; maximum segments, 197 (N=15); maximum tube length, 45 cm; maximum body length, 20 cm; orange coloration of the fore part (peristomium and segment 1) and of the ventral shield on segments 6–7; shape of the specialized enlarged cutting seta on A4 with an obliquely truncated distal end; this slightly concave section is heart-shaped and clearly asymmetrical; segments B1 and B2 with one lobe on the neuropodia. This additional description in the genus Spiochaetopterus confirms the limited geographical area of each species in this genus. In spite of the probable ability of planktonic larvae of Spiochaetopterus to disseminate throughout the Atlantic Ocean, the benthic adults of each species cover only a limited geographical area. In particular, the stem species S. costarum loses its cosmopolitan character.

We describe a new species of frog of the genus Chiasmocleis from the montane forests of southeastern Ecuador, at the western slopes of Cordillera del Cóndor, between 1,224‑1,630 m of elevation. Based on new sequences of mitochondrial and nuclear DNA we present phylogenetic relationships of the new species and its congeners. The phylogeny shows a close relationship to C. antenori, C. carvalhoi, C. magnova and C. tridactyla. The new species is part of a clade of species that were previously assigned to the genus Syncope. This clade has a sister relationship to a clade that contains all remaining species of Chiasmocleis. The new species differs from its congeners by its reddish-brown to dark-brown (sepia) dorsum with minute yellowish-white spots. Chiasmocleis parkeri sp. nov. is similar to Chiasmocleis antenori in lacking digit I of both hands and feet but Chiasmocleis parkeri differs in coloration, arrangement and size of pale spots, and the absence of a pale line in the canthal region. We describe the calls, which are characterized by having non-pulsed notes, and we provide ecological data from the type locality and adjacent areas.

We describe a new species of the genus Lycodon based on an adult male specimen from Thanh Hoa Province, Vietnam. Lycodon namdongensis sp. nov. is differentiated from its congeners by a combination of the following characters: dorsal scales in 17−17−15 rows, all smooth; supralabials 8; infralabials 10; one large loreal on each side, separated from the eye; cloacal single; ventral scales 218 (plus two preventral scales); subcaudals 85, paired; a total length of 723 mm; tail / total length ratio 0.205; dorsal head pattern whitish grey; dorsal surface of body with 23 narrow greyish cream bands; dorsal surface of tail with 14 cream bands; ventral surface of body mostly cream with a few small dark spots posteriorly; ventral surface of tail dark grey. Based on molecular comparisons, Lycodon namdongensis sp. nov. is recovered as a sister species to L. futsingensis with strong support values from all three analyses. The new species is at least 6.5% genetically divergent from other species within this clade as shown by a fragment of more than 1000 pbs of the mitochondrial cytochrome b. This discovery increases the number of Lycodon species known from Vietnam to 15.

A New Species

AbstractA new species of African clawed toad is described from the Bale Mountains region in southern Ethiopia. A series of small field samples indicate a maximum body length for females of about 50 mm. The new species is a 3-clawed Xenopus, distinguished by a rounded snout with relatively small eyes, a dark brown dorsal colouration lacking large spots or patches (which are common elsewhere in the genus), the absence of both a subocular tentacle and a metatarsal tubercle, and a small number of lateral line plaques (18 or 19 transverse plaques between eye and vent). The new species occurs in a region noted for the high proportion of endemic taxa in its fauna and flora; it occurs sympatrically with the single previously-known Ethiopian Xenofius, X. clivii, at around 2600 m asl., but is easily distinguished from this 4-clawed species. The new species has a chromosome number of 2n = 36; a series of biochemical and genetic studie indicate that it is most closely related to X. laevis and X. gilli and that it is relatively distant from the three species which are its nearest geographical neighbours, X. clivii, X. borealis and X. muelleri.

A New Species

A new species of the genusLycodonis described from Cao Bang Province, Vietnam, based on three individuals with distinct differences in morphology and molecular data. The new species is differentiated from its congeners by a combination of the following characters: dorsal scales in 17-17-15 rows, smooth throughout; supralabials usually eight (rarely nine); infralabials ten; one elongated loreal on each side, in contact with the eye; precloacal plate single; ventral scales 212–218 (plus one or two preventral scales); subcaudals 90 or 91; maxillary teeth 13 or 14; dorsal surface of body with 28 or 29 light body bands; dorsal surface of tail with 13 cream bands, forming a distinct blotch in the vertebral region. Based on phylogenetic analyses of mitochondrial cytochromebsequence data, the new species is recovered as the sister species to a clade containingL. multizonatusandL. liuchengchaoiwith strong support from the Bayesian analysis. The new species is at least 7.5% divergent from other species within this clade in uncorrected pairwise distance calculated using a fragment of more than 1000 bp of the mitochondrial cytochromeb.This discovery increases the number ofLycodonspecies known from Vietnam to 16.

A New Species

A new species of Guianacara is described from tributaries of the Essequibo River and the rio Branco in Guyana and northern Brazil. Guianacara dacrya, new species, can be diagnosed from all congeners by the possession of a unique infraorbital stripe and by the shape of the lateral margin of the lower pharyngeal jaw tooth plate. Guianacara dacrya can be further distinguished from G. geayi, G. owroewefi, G. sphenozona and G. stergiosi by the possession of a thin midlateral bar, from G. cuyunii by the possession of dusky branchiostegal membranes and from G. oelemariensis by the possession of two supraneurals. This species differs from most congeners by the presence of white spots on the spiny portion of the dorsal fin, the placement of the midlateral spot, the presence of filaments on the dorsal, anal and in rare cases the caudal-fin and from at least the Venezuelan species by several morphometric variables. Guianacara dacrya is known from the Essequibo, Takutu and Ireng River basins of Guyana and possibly from the rio Uraricoera in the rio Branco basin in Brazil. A key to the species is provided.
