A new species of the genus Leptobrachella,Leptobrachella damingshanensis sp.nov.is described from central Guangxi,China,based on morphological,molecular,and acoustic data.Phylogenetic analyses using a 16S rRNA gene fragment indicated that the new species formed an independent clade close to L.nahangensis and L.nyx.However,the new species differs from all known congeners based on a combination of the following characters:medium size (snout-vent length(SVL) 33.6-34.4 mm in males);pair of distinct jacinth humeral glands on proximal thigh area;rough dorsal skin with sparse jacinth tubercles and several short longitudinal ridges;creamy white ventral surface with small,creamy white glands on throat,chest,belly,and ventral surfaces of thighs,becoming more concentrated near lateral margin;webbing and lateral fringes absent on fingers,toes with rudimentary webbing and narrow lateral fringes;flanks with small irregular black spots;iris bicolored,upper half copper,fading to silver in lower half.Uncorrected p-distances were greater than 4.7％ between Leptobrachella damingshanensis sp.nov.and all homologous DNA sequences available for the 16S rRNA gene.The new species is only known to occur in the Damingshan National Nature Reserve,where it inhabits montane evergreen forests between 1000-1200 m a.s.I.

The Chinese tree shrew (Tupaia belangeri chinensis)is emerging as an important experimental animal in multiple fields of biomedical research.Comprehensive reference genome annotation for both mRNA and long non-coding RNA (IncRNA) is crucial for developing
A new Hairless (Hr) gene mutant mouse line (SHJHhr) was identified,which showed hairless skin in adult individuals as reported in rhino mice.Through Hr gene mutant identification with polymerase chain reaction (PCR) amplification and sequencing,seven muta
The highly speciose gekkonid genus Cnemaspis Strauch,1887 is polyphyletic,with three distantly related and geographically isolated clades from Africa,South Asia (SA),and Southeast Asia.At present,there are 85 known species within SA Cnemaspis,although the
We report a new species of the genus Micryletta from the montane evergreen forest in the Bidoup-Nui Ba National Park,Lam Dong Province,Langbian Plateau,southern Vietnam,based on molecular and morphological evidence.The new species is diagnosed by a combin
Salamanders are unique among tetrapods in their ability to regenerate the limbs throughout life.Like other poikilothermic amphibians,salamanders also show a remarkable capacity to survive long periods of starvation.Whether the physiological reserves neces
The Chantecler chicken,a unique Canadian indigenous breed,is well adapted to extremely cold environments.However,its genetic characteristics have not been well studied.Here,we analyzed the whole genomes of 10 Chantecler chickens and 121 worldwide chickens
Oxygen is an essential molecule for animal respiration,growth,and survival.Unlike in terrestrial environments,contamination and climate change have led to the frequent occurrence of hypoxia in aquatic environments,thus impacting aquatic animal survival.Ho
SOX9 (SRY-related HMG box gene 9) is an essential regulator of male sex determination and testis differentiation in many vertebrate species.However,the functional role of Sox9 in testis differentiation has not yet been identified in any reptilian species.
