Abstract

One of the small genera of the tribe Atrophini (subfamily Banchinae), the genus Amphirhachis, has been reported seven species in the world. Among them, four species (Amphirhachis fasciata, A. nigripalpis, A. rubriventris and A. tertia) from Oriental region, and four species(Amphirhachis fujiei, A. miyabi, A. nigra and A. tertia) from Eastern Palaearctic region. Unfortunately, there are no records in South Korea yet. This genus is easily distinguished from other genera of Atrophini following: clypeus strongly convex near side; posterior transverse carina of propodeum represented by a weak or faint vertical ridge at apex on each side; ovipositor sheath shorter than metasoma. In this study, the genus Amphirhachis is recorded for the first time with a newly recorded species (Amphirhachis tertia) from South Korea. New data on the taxonomy and distribution of Amphirhachis tertia are given. We also provide diagnosis and digital images of a newly recorded genus and species.
