Abstract

There are few records of beetles of the family Elateridae from Tanegashima Island, in the Ôsumi Islands, in the Ryukyu Islands, Japan, and the elaterid fauna of this island has not been reviewed. We examined newly collected specimens and reviewed the previous records from the island. In field work and from a colleague’s collection, we found 27 species, of which 13 were recorded for the first time on the island. As result 43 species are confirmed from this island and a checklist of all elaterid species from Tanegashima Island is provided.

Summary

Introduction

Tanegashima Island is the easternmost Ôsumi Islands, in the northernmost part of the Ryukyu Islands of Japan. The island is the second largest of the Ôsumi Islands, covering 444 km with a maximum elevation of 282 m (Geospatial Information Authority of Japan 2018, Kyushu Regional Forest Office 2018). The island occupies an important position biogeographically because it has a large lowland forest near the boundary between the Palearctic and Oriental regions. Chûjo (1973), Hirashima (1989), and Kishii (1999) listed 4, 10, and 16 species, respectively, of Elateridae from Tanegashima Island. Approximately 30 species have been recorded from this island (Kishii 1999, Ôhira 1996a, 2000, Ôtsubo 2013). 639 elaterid species have been recorded from Japan (Ôba et al 2015)
