Hoshina HidetoReview of the tribes Sogdini and Leiodini from Japan and North Chishima Islands. Part II. Genera Hydnobius and Leiodes (Coleoptera: Leiodidae)Acta Entomologica Musei Nationalis Pragae 52(supplementum 1): 1-168
Abstract: The species of the genera Hydnobius Schmidt, 1841 and Leiodes Latreille, 1797 in Japan and the North Chishima Islands (= North Kuril Islands) are revised. Until now, only one species of Hydnobius and ten species of Leiodes were recorded from Japan, none of them from the North Chishima Islands. In Hydnobius, one new species, H. enomotoi sp. nov. (Matua Island, Simushir Island, Ketoi Island) is described, and H. akitsuensis Hoshina & Sunada, 2003 is recorded for the first time from the North Chishima Islands. In Leiodes, twenty-four new species are described: L. kandai sp. nov. (Honshu), L. yoshidai sp. nov. (Shikoku), L. juzoi sp. nov. (Hokkaido: Rishiri Is.), L. yasudai sp. nov. (Hokkaido), L. yoshitakei sp. nov. (Hokkaido), L. masatsugui sp. nov. (Honshu), L. toyoshimai sp. nov. (Honshu, Shikoku), L. araii sp. nov. (Honshu), L. haradai sp. nov. (Shikoku), L. hijikatai sp. nov. (Honshu), L. kiuchii sp. nov. (Honshu, Shikoku), L. sakaii sp. nov. (Shikoku), L. naraharai sp. nov. (Ryukyus), L. shuheii sp. nov. (Ryukyus), L. kamezawai sp. nov. (Ryukyus), L. yukihikoi sp. nov. (Honshu, Kyushu), L. akiyamai sp. nov. (Shikoku), L. iwakirii sp. nov. (Kyushu), L. nagayamai sp. nov. (Hokkaido), L. ohtai sp. nov. (Ryukyus), L. ozakii sp. nov. (Honshu), L. shigehisai sp. nov. (Hokkaido), L. tanakai sp. nov. (Honshu, Shikoku), and L. yamauchii sp. nov. (Shikoku, Kyushu). Another three species are added to the fauna of Japan and the North Chishima Islands: Leiodes koreana Park & Ahn, 2007 (new to Japan: Honshu, Shikoku, Kyushu), Leiodes longitarsis Baranowski, 1993 (new to North Chishima Isl. and Hokkaido: Rishiri Is.), and L. rhaetica (Erichson, 1845) (new to North Chishima Isl.). Leiodes alpicola Nakane, 1963, syn. nov., and L. cooteri Park & Ahn, 2007, syn. nov., are synonymized with L. lucens (Fairmaire, 1855); L. izuensis Nakane, 1989, syn. nov., is synonymized with L. circinipes (Rye, 1873). Japanese species are divided into seven species groups, while some species are left as incertae sedis, without a group assignment. Relevance of selected taxonomic characters and zoogeography of the Japanese species of Leiodes are also discussed.
