Two reptiles, Mauremys mutica kami and Hemiphyllodactylus typus typus, are newly recorded from Haterumajima, the southernmost island of the Yaeyama Group, southern Ryukyus, on the basis of voucher specimens. Of these, M. m. kami was found in large number, and this strongly suggests that this freshwater turtle has already established a breeding population on this island. With respect to H. t. typus, only one individual, juvenile female, was found. However, considering possible parthenogenetic nature of its East Asian assemblages, this gecko may have also established on this island already. Besides these new records, our survey yielded additional specimens of Lepidodactylus lugubris, another parthenogenetic gecko non-native to Haterumajim Island. Characteristics of the dorsal pattern in these specimens indicate that the Haterumajima assemblage belongs to so-called “clone C” like assemblages of this gecko from all other islands of the Ryukyus exclusive of the Daito Group. Records of reptile species from this island are reviewed and problems requiring future investigations are clarified.
