    摘要:

    2022年11月在浙江省庆元县贤良镇采集到10只半叶趾虎属(Hemiphyllodactylus)蜥蜴,经形态比对和分子系统分析鉴定为香港半叶趾虎(H. hongkongensis),为浙江省爬行动物分布新记录种。标本体型较小,头体长大于尾长,颏鳞5或6枚,背鳞13 ~ 15行,腹鳞9或10行,第II-V指、趾扩展部攀瓣式分别为3(4)-4-4-4、3(4)-4(5)-4(5)-4(5),雄性具连续的肛前孔和股孔24或25个。浙江庆元的标本在形态特征上与香港半叶趾虎地模标本基本一致。基于线粒体ND2基因进行贝叶斯系统发育分析,浙江庆元的标本与香港半叶趾虎地模标本的序列聚成单系支,支持率达0.99,并且两者间的未校正遗传距离仅为1.6% ~ 1.7%,确定浙江庆元的标本为香港半叶趾虎。这是半叶趾虎属在浙江省的首次记录,说明该属物种可能有更大的分布范围。

    Abstract:

    During the fieldwork in November 2022, we collected 10 specimens of the gekkonid genus Hemiphyllodactylus Bleeker, 1860 (Squamata:Gekkonidae) in Qingyuan, Zhejiang Province, China, and identified them as H. hongkongensis by morphological comparisons and phylogenetic analyses. This is the first record of Hemiphyllodactylus in Zhejiang Province. In this study, the morphological characteristics of our specimens were compared with the type specimens of H. hongkongensis. Using mitochondrial ND2 gene sequences, we performed Bayesian phylogenic analyses in MrBayes 3.1.2 and calculated the uncorrected genetic distances within Hemiphyllodactylus in MEGA 7. All the new sequences in this study have been deposited in GenBank, and the other sequences used were retrieved from GenBank (Appendix 1). The morphological characteristics of the specimens collected in this study were consistent with those of the type specimens of H. hongkongensis:small body size (snout-vent length, SVL 44.44 ± 3.89 mm in adult females, n = 6; SVL 44.74 ± 2.97 mm in adult males, n = 4); the unique combination of 5 or 6 chin scales; a manual lamellar formula of 3(4)-4-4-4; a pedal lamellar formula of 3(4)-4(5)-4(5)-4(5); 24 or 25 continuous femoral and precloacal pores; 13﹣15 dorsal scales contained in diameter of eye; and 9 or 10 ventral scales contained in diameter of eye. In addition, Bayesian phylogenetic analyses recovered a well-supported clade consisting of our specimens and the type specimen of H. hongkongensis from Hong Kong, China (Fig. 3). According to ND2, the uncorrected genetic distance between our specimens and the type specimen of H. hongkongensis was 1.6%﹣1.7% (Appendix 2). In summary, the specimens collected in Qingyuan, Zhejiang Province were determined to be H. hongkongensis, which was the first record in Zhejiang Province. We further updated the elevation-range of H. hongkongensis, which is 550 m higher than the previous record.
