Range of Distribution of Eumeces okadae (Scincidae)

Abstract

1) Although Eumeces okadae is endemic to the Izu Islands, its range is only partly known because of the deficient study of the herpetofauna in these islands.
2) Its range as known up to now covers the five islands of Niijima, Shikinejima, Kozushima, Miyakejima, and Hachijojima. And there is a report that indicates its presence on Hachji-kojima (islet) and Aogashima (island), but for these islets a reinvestigation is needed. For the present, therefore, they are not included in the range.
3) In the present paper I report a newly recorded range of Eumeces okadae on the islands of Oshima, Toshima and Mikurajima.
4) For Aogashima (where Eumeces latiscutatus has been reported to live, but considered from the actual range of Eumeces okadae it may, with a reinvestigation, prove to be Eumeces okadae) and the neighbouring islets of the above-said eight islands in the range there is a possibility for Eumeces okadae to be found. On an island in the south of Aogashima, however, there is little hope of its discovery.
