抄録: Phylogenetic relationships among Asian and African lygosomine skinks of the Mabuya group were inferred from 825 base pairs of DNA sequences of mitochondrial 12S and 16S rRNA genes. Results indicated the presence of two distinct lineages within this group, of which one consisted of Lamprolepis and Lygosoma, and the other of Apterygodon, Dasia, and Asian and African Mabuya. Within the latter, African species of Mabuya first diverged from the remainder, leaving the Asian congeners together with the Apterygodon-Dasia clade. Our results, while suggesting the non-monophyly of the genus Mabuya, do not support the currently prevailing phylogeographical hypothesis which assumes the independent origins of Lamprolepis and Lygosoma from the Asian Mabuya-like stock. On the other hand, our results suggest that morphological and karyological similarities between the Apterygodon-Dasia clade and Lamprolepis are attributable to symplesiomorphy, while their ecological similarity to convergence. Morphological and karyological character states unique to Apterygodon are supposed to have evolved from those exhibited by Dasia.
