Agalope oshikirii n. sp., the first chalcosiine fossil (Lepidoptera, Zygaenidae) from Akita Prefecture, Japan

Agalope oshikirii n. sp. (Zygaenidae, Chalcosiinae) is described from the uppermost Miocene–Pliocene Sanzugawa Formation in Akita Prefecture, northern Japan. Because we found a single fossil forewing in this study, we give a table of the forewing characters of various groups of the genus Agalope and related genera and compared them with this new species, confirming that it does not match any of the species. This is the first discovery of chalcosiine fossils in Japan and provides evidence of a historically broader distribution of the genus.
