ResumoUsing starch gel electrophoresis, we examined allozyme variation at 24 presumptive loci in specimens of Tylototriton andersoni collected from three islands of the Ryukyu Archipelago: Amami-Oshima, Tokunoshima, and Okinawajima. Levels of genetic variability within island sam- ples (H = 0.050-0.082, P = 0.21-0.38, A = 1.25-1.58) are within the intrapopulational range previously reported for other salamandrids. The sample from Okinawajima is different from the Amami-Oshima and Tokunoshima samples with Nei's genetic distance (D) of 0.09-0.12, whereas the level of differentiation between the latter two is lower (D = 0.02). This pattern of genetic differentiation within T. andersoni coincides well with the geological history of the three islands.
