Discovery of a new species of the genus Triarthron Märkel, 1840 (Coleoptera, Leiodidae) with a key to Japanese species of the tribe Sogdini

Abstract

In the genus Triarthron (Coleoptera, Leiodidae, Leiodinae), only two species are known to occur in Palearctic and Nearctic regions. In this paper, a new species in Japan, Triarthron itoi Hoshina, sp. nov., is described. This brings the number of species in the genus to three. A key to the Japanese species of the tribe Sogdini is given.
