Research Abstract

We analyzed variations in approximately 1,200 base positions of mitochondrial DNA sequences in order to discuss genetic diversity and conservation of Goniurosaurus kuroiwae from the Central Ryukyus, Japan. Results do not support the relationships hypothesized on the morphological ground in that the present results strongly suggest that the primary dichotomy, with substantial genetic divergence, between G. k. splendens from the Amami Island Group and the remaining subspecies from the Okinawa Island Group, and that the presence of at least six independent lineages within the latter, indicating non-monophyly for each of G. k. kuroiwae and G. k. orientalis. All populations are endangered from the viewpoint of conservation genetics.
