My morphological and molecular phylogenetic analyses for Gekko japonicus species group corroborated independent species status of five putative undescribed forms in Japan and Taiwan. The latter analysis further revealed that the species occurring near southern limit of the whole geographic range were collectively older, suggesting this species group has originated in the southern part, then expanded its range to north with iterative speciation. The species in the insular regions were highly polyphyletic, suggesting parallel colonization by several clades and subsequent speciation. Disjunct distributions of a few species in Kyushu were also considered to be results of recent colonization.
