A New Species of Leptolalax （Anura： Megophryidae） from Southern China

A new species, Leptolalax laui sp. nov. is described based on specimens collected from Hong Kong and Shenzhen City, Guangdong Province, China. The new species can be distinguished from other known congeners by morphological and molecular data. The new species is characterized by the following characters： 1） small size （adult males SVL 24.8.1 mm-26.7 mm）; 2） near immaculate creamy white chest and belly; 3） broad lateral fringes on toes; 4） head longer or as long as wide; 5） distinct dark brown spots in flank; 6） moderate dermal fringes on fingers; 7） brown or reddish-brown dorsum with fine round scattered tubercles; 8） thin traverse brownish-grey bars on the dorsal surface of tibia and lower arms; 9） longitudinal ridges under toes not interrupted at the articulations.

Three new species of Leptolalax from Thailand (Amphibia, Anura, Megophryidae)

Three new megophryid species, Leptolalax melanoleucus, L. fuliginosus, and L. solus, are described from southwestern and southern Thailand on the bases of acoustic and morphological characteristics. Leptolalax melanoleucus and L. fuliginosus are similar to L. pelodytoides from northern Thailand, but differ from it completely in advertisement call characteristics and ventral color. Leptolalax solus is similar to L. heteropus from peninsular Malaysia, but differs from it by advertisement call, as well as by some body proportions. The distributional pattern of Leptolalax within Thailand is discussed.     

中国蛙科一新种——版纳大头蛙(两栖纲:无尾目)

经核查和鉴定中国云南等地原定名为大头蛙[Limnonectes kuhlii(=Rana kuhlii Tschudi,1838)]的标本及相关文献资料,并与产地为印度尼西亚的爪哇大头蛙(Limnonectes kuhlii)模式标本的有关描述相对比,两者在其形态、染色体及线粒体基因分化等特征上均有明显区别,因此将云南、广西等地标本的种名改订为新种,即版纳大头蛙(Limnonectes bannaensis,sp.nov.)。其主要鉴别特征是:1)背面较光滑,具少数细肤棱,体后部有小圆疣;2)体背面浅褐色或灰褐色,肤褶上有黑纹;3)蝌蚪尾部具深色斑纹,但尾后半段不呈黑色;4)其染色体组型为2n=22(20m 2st)。而爪哇产大头蛙:1)背面粗糙,体背部、胫部和肛部周围满布圆形疣粒;2)体背面为黑大理石色或为黑色;3)蝌蚪尾部后半段为黑色;4)染色体组型为2n=26,5对大染色体,8对小染色体,除第8对为亚端部着丝粒外,其余均为中部和亚中部着丝粒。     

A new species of the genus Leptolalax(Anura:Megophryidae) from southern Vietnam

We describe a new species of megophryid frog from Phu Yen Province in southern Vietnam. Leptolalax macrops sp. nov. is distinguished from its congeners by a combination of the following morphological attributes:(1) body size medium(SVL 28.0–29.3 mm in three adult males, 30.3 mm in single adult female);(2) supra-axillary glands present, creamy white; ventrolateral glands indistinct;(3) tympanum externally distinct;(4) dorsal skin roughly granular with larger tubercles, dermal ridges on dorsum absent;(5) rudimentary webbing present between fingers Ⅰ–Ⅱ and Ⅱ–Ⅲ; rudimentary webbing between all toes; fingers and toes without dermal fringes;(6) in life ventral surface greyish-violet with white speckling;(7) supratympanic fold distinct, dark brown in life;(8) iris bicolored, typically golden in upper half, fading to golden green in lower half;(9) tibia short(TbL/SVL 0.44–0.45 in males); and(10) eyes large and protuberant(ED/SVL 0.15–0.16 in males).From all congeners for which comparable sequences are available, the new species differs markedly in the 16 S rRNA mitochondrial gene sequence(P-distance5.7%). The new species is currently known only from montane evergreen tropical forests of Song Hinh District, Phu Yen Province, and M'Drak District of Dak Lak Province at elevations of 470–630 m a.s.l.. We suggest the new species should be considered as Data Deficient following the IUCN's Red List categories. We also report a previously unknown Leptolalax mt DNA lineage from an evergreen tropical forest in the Hoa Thinh District of Phu Yen Province,which may also represent an undescribed species.     

A New Species of the Genus Xenophrys(Amphibia: Anura: Megophryidae) from Libo County,Guizhou, China

A new species of the genus Xenophrys is described from a karst cave environment of Libo County, Guizhou Province, Southern China. The new species, Xenophrys liboensis sp. nov., is distinguished from its congeners by a combination of the following characters: 1) tympanum distinct; 2) vomerine teeth present; 3) the length of lower arm and hand larger than the half of snout-vent; 4) heels overlapped slightly when the flexed legs are held at right angles to the body axis; 5) toe tips with rudimentary webs and without grooves; 6) dermal fringes moderate; 7) tubercles on the dorsum forming an X-shaped weak ridge; 8) horn-like tubercle at the edge of the upper eyelid distinct; 9) color of the iris in life is brown. In Bayesian phylogenetic analysis of 22 species of Xenophrys, all the individuals of X. liboensis sp. nov. clustered into a monophyletic clade with high posterior probabilities. In addition, the ranges of genetic divergences of X. liboensis sp. nov. with other species were interspecific rather than intraspecific. Based on the above evidences, we consider that X. liboensis sp. nov. is a valid species in Xenophrys.
