摘要
2017年12月对南海永兴岛的爬行动物进行了短期调查,发现3种壁虎科Gekkonidae动物,分别是截趾虎Gehyra mutilata、原尾蜥虎Hemidactylus bowringii和疣尾蜥虎H.frenatus。其中,截趾虎和原尾蜥虎为中国南海岛屿的新记录。
Three species of Gekkonidae were found from Yongxing Island during a herpetological survey in December, 2017. According to their external morphological characterisctics and comparison with the specimens from Sanya, Wanning, Qionghai and Haikou cities throughout Hainan Island, they were identified as Gehyra mutilata, Hemidactylus bowringii and H. frenatus. G. mutilata and H. bowringii were found in the island of South China Sea for the first time. G. mutilata is native to southeast Asia and is widely distributed throughout Sri Lanka, Burma, Malaysia, southeast China, The Philippines, Indonesia, New Guinea, French Polynesia, Pitcairn Islands, Mascarenes and Seychelles, western Mexico, Maui, Hawaii. H. bowringii is native to south mainland, Taiwan, Hainan and Hong Kong of China, as well as Vietnam(including Hon Thom Island and Ku Lao Pan Jang Island), Myanmar, Nepal, Bhutan and Japan(Pyukyu Islands). As the largest innate island in South China Sea, Yongxing Island is more than 2 km~2 in area and about 330 km and 410 km far from Sanya and Haikou cities of Hainan Island. The finding indicated that the reptile fauna in the South China Sea Islands has a close relationship to Hainan Island. It will investigate further in other islands of the South China Sea and reveal in molecular genetics level.
