A New Species

A new species, Amolops yunkaiensis sp. nov. is described based on a series of specimens from Ehuangzhang Nature Reserve and Yunkaishan Nature Reserve, southwestern Guangdong Province, China. The new species can be distinguished from all known congeners by molecular divergence in the mitochondrial 16S rRNA, 12S rRNA and CO1 genes, and a combination of the following characters: relatively small body size, SVL 31.8–34.1 mm in adult males, 35.2–39.0 mm in adult females; numerous raised large warts on dorsum and flanks; dorsal body olive-brown or light brown with dark brown blotches; absence of vomerine teeth; absence of tarsal glands; presence of a pair of subgular vocal sacs, nuptial spines on the first finger, and sparse translucent tubercles on the lower jaw, forechest, posterior belly and ventral thigh in male. Hence, the genus Amolops contains 52 species, 29 of which occur in China.

A New Species

We describe a new Pristimantis from La Libertad and Rumiloma, Reserva Mazar, Andes of Southeastern Ecuador, at elevations between 2895–3415 m. This species is assigned to the P. orestes group, from whose members it differs by its small body size (adult males ≤ 18.1 mm; adult females ≤ 23.7 mm), usually reticulated ventral pattern, and visible tympanum. The vocalization of the new species consists of a series of calls; each call is composed by a pulsed, non-modulated note in frequency, and with a dominant frequency of 3122–3171 Hz. A molecular phylogeny based on a fragment of the mitochondrial gene 12S shows that the new species is sister to Pristimantis simonbolivari.

A New Species

A new species, Xenophrys insularis sp. nov., is described based on a series of specimens collected from Nan’ao Island, Shantou City, Guangdong Province, China. The new species is a separately evolving lineage that was robustly supported by the phylogenetic analysis based on the mitochondrial CO1 + 12S rRNA + 16S rRNA genes; morphologically, it can be distinguished from other known congeners by the following combination of characteristics: body size moderate, SVL 38.6–41.2 mm in adult males, 47.1 mm in a single adult female; snout obtusely rounded in dorsal view; head width slightly larger than head length; strong vomerine ridge bearing vomerine teeth; margin of tongue weakly notched behind; supratympanic fold forming a large swollen supraaxillary gland above insertion of arm; hindlimbs relatively short, heels not meeting when thighs are held at right angles to body, tibio-tarsal articulation reaches forward the posterior edge of tympanum; fingers and toes without lateral fringes, with rudiment of web at bases of toes, distinct subarticular tubercle only at the base of each finger and toe; single vocal sac in males; gravid female bears pure white oocytes. Xenophrys insularis sp. nov. is endemic to the Nan’ao Island and represents the first Xenophrys species found on and possibly endemic to a small offshore island.

A New Species

Amolops shuichengicus sp. nov., a new species of the A. mantzorum group is described from Guizhou, southwest China, on the basis of significant molecular divergences in 16S + CO1 genes and the combination of morphological characteristics: small body size, SVL 34.6–39.6 mm in adult males and 48.5–55.5 mm in adult females; dorsal skin relatively smooth; presence of vomerine teeth; presence of cream maxillary gland from lower edge of eye to the anterior of supratympanic fold; presence of supratympanic folds and glandular dorsolateral folds; tympanum indistinct; absence of a circummarginal groove on the disk of the first finger; presence of supernumerary tubercles below the base of fingers III and IV; absence of outer metatarsal tubercle and tarsal glands; males without vocal sacs. In addition, evidenced by the phylogenetic analyses in this study and literature data, we suggest that A. liangshanensis should be synonymized with A. loloensis and the records of A. marmoratus in Yunnan, China should be referred to A. afghanus. Following our proposal, the genus Amolops contains 57 species, with 32 recorded from China.

A New Species

We describe a new species of Zhangixalus from southern Yunnan of China, Vietnam, and Thailand based on morphological and molecular evidence. The new species had been confused with Zhangixalus smaragdinus (Blyth, 1852) in the past. Zhangixalus pachyproctus sp. nov. can be distinguished from Z. smaragdinus morphologically by the protruding vent in adult males, large thick grey reticular mottles below the white stripe on flank, more oblique snout in profile and wider head, longer snout, greater internarial distance, larger tympanum and longer hindlimb. The new species can be distinguished from other species of Zhangixalus with green dorsum by the following combination of characters: body size larger (SVL of adult males: 74.2–83.3 mm; SVL of adult female: 102.4 mm); dorsum smooth; narrow white stripes along edge of the lower jaw, body sides, outer side of limbs and above the vent; absence of brown bands on canthus rostralis, upper eyelid and supratympanic fold; webbing between fingers and toes complete except between the first two fingers; and internal single subgular vocal sac. Phylogeny based on comparison of 16S rRNA sequences suggests that the new species is the sister taxon to Z. smaragdinus and the two species differ by 7.63% in the uncorrected pairwise distance of 16S sequences.

We describe a new, medium-sized Leptolalax species from Vietnam. Leptolalax petrops sp. nov. is distinguished from its congeners by a combination of having a medium-sized body (23.6–27.6 mm in 21 adult males, 30.3–47.0 mm in 17 adult females), immaculate white chest and belly, no distinct black markings on the head, highly tuberculate skin texture, toes lacking webbing and with narrow lateral fringes, and a call consisting of an average of four notes and a dominant frequency of 5.6–6.4 kHz (at 24.5–25.3 °C). Uncorrected sequence divergences between L. petrops sp. nov. and all homologous DNA sequences available for the 16S rRNA gene are >8%.

A New Species

A new species of the genusGracixalus,Gracixalusyunnanensissp. n., is described based on a series of specimens collected from southwestern and southern Yunnan, China. This species is distinguished from all other known congeners by a combination of the following characters: relatively small body size in adult males (SVL 26.0–34.2 mm); dorsal surface yellow brown or red brown; distinctive conical asperities on dorsum; males with an external subgular vocal sac and linea masculina; throat, chest, and belly nearly immaculate; venter surface orangish with yellow spots, semi-transparent; snout rounded; supratympanic fold distinct; iris bronze; lack of white patch on temporal region; tibiotarsal projection absent; sides of body nearly smooth with no black blotch; finger webbing rudimentary; and toe webbing formula I1.5–2II1.5–2.7III.5–3IV2.5–1.5V. Genetically, the new species diverges from its congeners by 2.2%–14.1% (uncorrected p-distance) and is closest toG.guangdongensis. However, the new species can morphologically be separated fromG.guangdongensisby distinctive conical tubercles on dorsum (versus absent), lateral surface nearly smooth with no black blotches on ventrolateral region (versus lateral surface rough, scattered with tubercles and black blotches on ventrolateral region), snout rounded (versus triangularly pointed), iris bronze (versus iris brown), and ventral surface orangish (versus throat and chest creamy white and belly light brown).
