    摘要: We describe a new frog species of Ceratobatrachidae, assigned to the genus Liurana, from Medog, Xizang, China. The new species can be distinguished from its congeners by:(1) smaller body size;(2) head length smaller than head width;(3) tibiotarsal articulation reaching between the eye and nostril when adpressed;(4) distinct tympanum;(5) digital disc absent;(6) metacarpal tubercles absent;(7) metatarsal tubercles indistinctive;(8) supernumerary tubercles below the base of finger absent; and(9) finger I much shorter than finger II. Phylogenetic analyses based on a single mitochondrial gene, as well as the combined sequences of one mitochondrial and two nuclear genes, both support the new species as an independent lineage. In addition, the uncorrected genetic distance of COI between the new species and the closest congener, L. xizangensis, was 9.4%. The discovery of another new species of the genus Liurana from the same region suggests that the diversity within this genus requires more comprehensive investigation.

    摘要: The genus Ablepharus represents a morphologically diverse group of lizards, comprising approximately 19 species distributed across Asia. However, due to challenges in sample collection, the taxonomy and phylogeny of this genus remain poorly resolved. In this study, we identified and described a novel species of Ablepharus from western Xizang, China, through morphological analysis and molecular phylogenetics. Phylogenetic reconstruction based on mitochondrial DNA(ND2) sequences showed that the new species formed a strongly supported sister lineage with A. ladacensis and A. himalayanus, while exhibiting significant genetic divergence from all other congeners. In addition to its genetic distinctiveness, the new species can be characterized by a combination of the following morphological characters:(1) eyelids partially fused;(2) tympanum sunken;(3) supranasal scales absent;(4) prefrontals separated from each other;(5) supraoculars 4;(6) supralabials 7, 6<sup>th</sup> largest;(7) infralabials 6 or 7;(8) scale rows across neck and back 6;(9) scales encircling midbody 32;(10) midventral scales from last chinshield to precloaca 72–80;(11) subcaudals 110–125;(12) lamellae beneath 4<sup>th</sup> finger 13–16, beneath 4<sup>th</sup> toe 18–21;(13) body brownish-olive, devoid of spots, venter brick-red. This study highlights the underexplored species diversity within Ablepharus in China and provides new insights into the taxonomy and evolutionary relationships of the genus.
