    摘要:

    2024年10月28日在广西壮族自治区贺州市大桂山国家森林公园采集到3号半叶趾虎属(Hemiphyllodactylus)样本(标本号GXNU2024110801 ~ GXNU2024110803),形态上与都庞岭半叶趾虎(H. dupanglingensis)高度相似。基于线粒体ND2基因的系统发育分析表明,3号标本与都庞岭半叶趾虎地模标本聚为一支,且与都庞岭半叶趾虎的未校正遗传距离0.017,小于属内其他物种之间的遗传距离(0.048 ~ 0.305)。经过形态比较和系统发育分析,确认3号标本为半叶趾虎属的都庞岭半叶趾虎。此前都庞岭半叶趾虎仅记录分布在湖南,此发现为该物种在广西的分布新记录,为都庞岭半叶趾虎的地理分布和系统发育提供了更多的信息。

    Abstract:

    Hemiphyllodactylus dupanglingensis was previously known only from Hunan, China. On October 28, 2024, three specimens (No. GXNU2024110801 ~ GXNU2024110803), exhibiting morphological features similar to those of H. dupanglingensis, were collected from Daguishan National Forest Park, Hezhou, Guangxi Zhuang Autonomous Region, China. For the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene, the sequencing peak maps of three sequences were evaluated and manually corrected in this study, and a total of other 23 sequences from 16 species of Hemiphyllodactylus were retrieved from GenBank (Table 1). Bayesian inference (BI) analysis was performed via PhyloSuite. The phylogenetic analysis based on ND2 gene revealed that the specimens and H. dupanglingensis specimens clustered together, with uncorrected pairwise distances (p-distance) of 0.017 (Table 3), which is less than the p-distances between species of the genus Hemiphyllodactylus (0.048 ~ 0.305). Considering both morphological characteristics and molecular phylogenetic analysis, it was determined that the two specimens collected in Hezhou were H. dupanglingensis, which was a new record species for amphibian distribution in Guangxi Zhuang Autonomous Region.
