    摘要:

    2023年7月24日,在云南省红河哈尼族彝族自治州河口瑶族自治县采集到2只壁虎。经形态学特征比较,这2号标本与南蹼趾壁虎(Gekko palmatus)的特征相符:鼻孔与吻鳞相接,鼻间鳞1或2枚;体背具疣鳞,而四肢无疣鳞;指、趾间蹼发达;雄性肛前孔21或25个;尾基部每侧肛疣1个;枕部有一对深褐色斑块;颈部至尾基有4或5条深褐色横斑。基于16S rRNA基因序列重建的系统发育关系显示,其与南蹼趾壁虎聚为一支,遗传距离仅为0.5%,而与多疣壁虎亚属内其他物种间的遗传距离则在2.6% ~ 17.6%。综合考虑形态特征和系统发育分析的结果,鉴定这2号标本为南蹼趾壁虎。且此物种为云南省爬行动物分布新记录种。

    Abstract:

    This study aims to confirm the taxonomic identity of gecko specimens collected in Yunnan Province, China, and determine whether they represent a new reptile record for the province. On July 24, 2023, two gecko specimens were collected in the Hekou Yao Autonomous County within the Honghe Hani and Yi Autonomous Prefecture of Yunnan Province, China. First, they were identified based on morphological characteristics described by Boulenger (1907) and Song et al. (2024). Then, phylogenetic analyses based on maximum likelihood (ML) and Bayesian inference (BI) approaches were performed using the 16S rRNA gene to assess genetic relationships among all the species used in this study. Finally, genetic distances were calculated via the uncorrected pairwise distance (p-distance) model in MEGA X. Morphological comparison suggests that the new specimens are Gekko palmatus:nares in contact with the rostral, with 1 or 2 internasals; tubercles present on dorsum but absent on the limbs; webbings between the fingers and toes well developed; 21 or 25 precloacal pores in males; one postcloacal tubercle on each side of the tail base; a pair of dark-brown plaques on the occiput; 4 or 5 dark-brown stripes from the nape to the caudal base (Fig. 2, Table 2). Phylogenetic analyses also reveal that these specimens cluster with G. palmatus (Fig. 3), with high node supports (ultrafast bootstrap approximation, UFB 98; Bayesian posterior probability, BPP 1.00). Moreover, the genetic distance between the newly collected specimens from Yunnan and those from other locations is 0.5%, which is significantly lower than the genetic distances (ranging from 2.6% to 17.6%) among other species within the subgenus Japonigekko (Table 3). Both the morphological characteristics and phylogenetic insights identify the specimens as G. palmatus, which represents the first documented occurrence of this species in Yunnan Province, China. This finding expands the known distribution of G. palmatus and contributes to the herpetofaunal diversity records of this region.
