A new species of the genus Tylototriton is described in this article based on morphological and genetic evidence. The new species is identified belonging to the T. asperrimus group and is similar to T. wenxianensis. The diagnostic characters of the new species are as follows: dorsal ridge broad and thick,its width approximately equal to eye diameter(P < 0.001); tail height greater than width at base of tail(P < 0.001); no villous genital papilla found inside the male anal fissure; nodule-like warts,along lateral margin of the trunk,bulge and forming tubercles,and thin and transverse striae present between the tubercles.

To explore and enrich the molecular mechanisms of thyroid hormone receptors （TRs） in the metamorphosis of amphibians, the cDNA sequences of TRa and TRβ in Microhyla fissipes were cloned and characterized. TRa was 1 706 bp in length with an open reading frame （ORF） of 1 257 bp encoding a predicted protein of 418 amino acids and TRβ was 1 422 bp with an ORF of 1 122 bp encoding a predicted protein of 373 amino acids. Their protein sequences contained 4 conserved domains of the nuclear receptor superfamily with two highly conserved cysteine-rich zinc fingers in the DNA-binding domain, whereas TRβ was 42 amino acids shorter in its A/B domain than TRot. Highly-conserved sequences and structures indicated their conserved functions during metamorphosis. TRa expression reached peak at 12 h and then decreased from 12 h to 48 h. While dramatically up-regulated TRβ was observed after exposure of T3 within 24 h, and it was down-regulated from 24 h to 48 h. The expression pattern of TRβ is similar to that in the natural metamorphosis. Furthermore, tadpoles treated 24 h also resembled the climax of metamorphosis tadpoles and TRβ expression had higher responsiveness than TRa to T3 in M. fissipes. These results suggest M. fissipes may serve as the model to assay environmental compounds on TH signaling disruption.

The complete mitochondrial genome of Nanorana pleskei from the Qinghai-Tibet Plateau was sequenced. It includes 17,660 base pairs, containing 13 protein-coding genes, two rRNAs and 23 tRNAs. A tandem duplication of tRNAu^t gene was found in this mitochondrial genome, and the similarity between the two tRNAMet genes is 85.8%, being the highest in amphibian mitochondrial genomes sequenced thus far. Based on gene organization, 24 types were found from 145 amphibian mitochondrial genomes. Type 1 was present in 108 species, type 11 in 11 species, types 5, 16, 17, and 20 each in two species, and the others each present in one species. Fifteen types were found in Anura, being the most diversity in three orders of the Lissamphibia. Our phylogenetic results using 11 protein-coding gene sequences of 145 amphibian mitochondrial genomes strongly support the mo- nophyly of the Lissamphibia, as well as its three orders, the Gymnophiona, Caudata, and Anura, among which the relationships were （（Gymnophiona （Caudata, Anura））. Based on the phylogenetic trees, type 1 was recognized as the ancestral type for am- phibians, and type 11 was the synapomorphic type for the Neobatrachia. Gene rearrangements among lineages provide meaning- ful phylogenetic information. The rearrangement of the LTPF tRNA gene cluster and the translocation of the ND5 gene only found in the Neobatrachia support the monophyly of this group; similarly, the tandem duplication of the tRNAMet genes only found in the Dicroglossidae support the monophyly of this family

In order to analyze population genetic structure at multiple spatial scales, microsatellite loci were developed for the ornamented pygmy flog （Microhylafissipes）, and 15 polymorphic microsatellite loci were successfully screened from 105 individuals, of which 82 from four populations distributed in the Sichuan Basin and 23 from the Sangzhi population in western Hunan. Five loci were found to deviate significantly from Hardy-Weinberg equilibrium in one to three popu lations, probably due to small sample size or null alleles. The average number of alleles in all loci was 8.5, ranging from 4 to 13, and the observed and expected heterozygosity ranged from 0.26 to 0.90 and 0.63 to 0.90, respectively. The Sangzhi population and the remaining four populations can be clearly separated using Bayesian clustering methods, showing that the genetic structure of M. fissipes was probably affected by the topography, especially mountain barriers. These polymorphic microsatellite loci could be used for further study on the landscape genetics of this highly adaptive and widely distributed species.

The concave-eared torrent frog(Odorrana tormota) is the first species of tailless amphibian that was evidenced to phonate and detect ultrasounds. We employed anatomic and histological methods to examine the phonatory organs, including the floor of the buccal cavity, vocal cords and glottis, of O. tormota and its sympatric species including O. graminea, O. schmackeri, and Amolops wuyiensis with different fundamental frequencies, and Pelophylax nigromaculatus as a control. Our results reveal that O. tormota possesses specialized phonatory organ structures, with thinner vocal cords modulated by a moderately stronger muscular mastoideus between the medial vocal cords and the lateral cricoid cartilages, and more elastic mouth floor to likely supply faster air stream which could make the vocal cords vibrate at higher frequencies, larger relative distance between the two muscles m. intermandibulares(RDMI), and higher nucleus density of m. intermandibularis(NDMI) and m. geniohyoideus(NDMG). The results of Pearson’s correlation tests between the mean values of the above measurements and the fundamental frequencies from the five species imply that all the specialized phonatory organ structures mentioned above might be favored by higher frequency of phonation of O. tormota.
