Figure 2 shows genetic grouping of samples derived from the UPGMA cluster- ing of pairwise D matrix. Populations currently assigned to E. in. marginatus were grouped together with high genetic similarities. By contrast, a great genetic heterogeneity was confirmed for E. m. oshimensis in the current delimitation, indi- cating a relatively distinct differentiation between the southern Amami and the northern Amami-southern Tokara assem- blages, as reported previously (Kato et al., 1994). In this analysis, the lotorishima sample was located in the cluster otherwise consisting of the northern Amami-southern Tokara E. m. oshimensis. The four examined specimens from lotorishima Island invariably had a medial white line not exceeding the proximal one third of the tail and 34 rows of midbody scales, and lacked the postnasal scale.
