Abstract

An updated herpetofaunal checklist of Hon Son Island, Rach Gia Bay, Kien Giang Province, southern Vietnam is presented which reports of new records for Kaloula pulchra, Sylvirana cf. mortenseni, Cyrtodactylus sp., and Gehyra mutilata bringing the island total to 21 species. Cyrtodactylus sp. is an unidentified granite-cave adapted species that occurs in syntopy with the granite-cave adapted C. eisenmanae, bringing the total number of Cyrtodactylus on this tiny island (11.5 km2) to three. The implications of highly specialized syntopic congeneric ecomorphs is discussed.

摘要

更新后的越南广义省拉查格湾鸿山岛爬行动物名录，报道了华丽射毒蛙、莫氏攀蜥、西里维拉纳 cf. 莫滕森氏蜥蜴、马来闭壳龟新纪录，使该岛物种总数达到 21 种。西里维拉纳 cf. 莫滕森氏蜥蜴是一种未被识别的适应于花岗岩洞穴的物种，与适应于花岗岩洞穴的西里维拉纳 cf. 伊森曼氏蜥蜴同域分布，使这个仅有 11.5 平方公里的小岛上的西里维拉纳属蜥蜴物种总数达到 3 种。本文讨论了高度特化的同域近缘生态型的意义。
