摘　　要：2023年9月,在广东省珠海市进行两栖爬行动物野外调查时,采集到5号蜥虎属Hemidactylus标本。标本体型较大,身被锥状具棱疣鳞,体中段疣鳞16~17列;肛前孔和股孔不连续;每侧2~3个肛疣。经形态特征比较,并基于线粒体ND2基因片段构建的蜥虎属部分物种的系统发育分析结果,确认为滕氏蜥虎H.tenkatei,系我国的首次记录。梳理文献发现,滕氏蜥虎与密疣蜥虎H.brookii历史上长期混淆,最近才被确定种级地位。我国香港、澳门和台湾此前记录有密疣蜥虎分布且已形成归化种群,因缺少分子证据仍不能确定其是密疣蜥虎还是滕氏蜥虎。目前,滕氏蜥虎已在珠海市形成繁殖种群,但现有证据尚不能确定其是否会对本土物种的生存造成威胁。未来需进一步关注它们的种群状况及对中国本土物种的生态影响。A total of five Hemidactylus specimens were collected during the herpetological investigation conducted in Zhuhai City,Guangdong Province,China in September 2023.The specimens have a combination of the following characters:snout-vent length 42.1−65.2 mm;9−11 supralabials,8−9 infralabials;tubercles large and keeled,16 or 17 longitudinal tubercle rows at mid dorsum;7 or 8 precloacal-femoral pores on each thigh separated medially by four non-pore-bearing scales;2 or 3 postcloacal tubercles on each side.Based on morphological comparison and phylogenetic analysis of ND2 gene for Hemidactylus species,these specimens were confirmed as H.tenkatei,a first record in China.The classification status of H.tenkatei and H.brookii had been determined recently using morphological re-examinations,by which H.tenka⁃tei was recognized as a full species.H.brookii was previously recorded in Hong Kong,Macao and Taiwan,China,and had formed a naturalized population.However,due to the lack of molecular vouchers,it is unable to confirm whether the species occurred in China is H.tenkatei or not.Currently,H.tenkatei has established reproductive populations in Zhuhai,their population status and ecological effects on native species should be further studied to determine the biosecurity threat potential.
