摘要

我们在一个综合分类框架中描述了来自印度东南部的两个新的斑点地栖壁虎属(壁虎属)。新发现的物种与其他8个群落成员的线粒体序列差异为13.0 ~ 16.7%,与其他8个群落成员的线粒体序列差异为10.4%。新种的形态学诊断是由带状物种C. aravindi、C. speciosus、C. rishivalleyensis和C. yakhuna的四对斑点(偶尔融合成8字形斑纹)的背部斑点模式;和带有三对或更少斑点的C. collealensis和C. srilekhae的斑点物种;在C. chengodumalaensis身上没有任何扩大的背部鳞片,而在C. varadgirii身上,在背侧眼角和下颌角下没有一块扩大的大致六角形鳞片。这两个新物种只能根据身体大小、相对身体宽度和其他统计上显著的、尺寸校正的形态计量特征的微小差异来区分。这些是第一批来自印度东南海岸热带干常绿栖息地的特有蜥蜴。

Two new spotted species of the Cyrtodactylus (Geckoella) collegalensis (Beddome, 1870) complex from the south-eastern coast of India (Reptilia: Squamata)
We describe two new spotted species of ground-dwelling gecko of the genus Cyrtodactylus (Geckoella) from southeastern India in an integrative taxonomic framework. The new species are recovered as sister taxa within the C. collegalensis species complex, with 13.0–16.7% uncorrected mitochondrial sequence divergence from the other eight members of the C. collegalensis complex and 10.4% from one another. The new species are morphologically diagnosed by a spotted dorsal pattern of four pairs of spots (occasionally fused into figure 8-shaped markings) from the banded species C. aravindi, C. speciosus, C. rishivalleyensis and C. yakhuna; and from the spotted species with three or fewer pairs of spots in C. collegalensis and C. srilekhae; and from C. chengodumalaensis by the absence of any enlarged dorsal scales and from C. varadgirii by the absence of a patch of enlarged roughly hexagonal scales on the canthus rostralis and beneath the angle of the lower jaw. The two new species can only be differentiated from each other based on slight differences in body size, relative body width and other statistically significant, size-corrected morphometric characters. These are among the first endemic lizards from Tropical Dry Evergreen habitats along the southeast coast of India.
