The genus Paleosepharia Laboissière, 1936 in Taiwan: review and nomenclatural changes (Coleoptera, Chrysomelidae, Galerucinae)

Abstract

Taxonomic study of species of the genus Monolepta Chevrolat, 1836 with subscutellar incised ridges in males and occurring in Taiwan resulted in the transfer of all species to Paleosepharia Laboissiere, 1936: P. amiana (Chujo, 1962), comb. n., P. formosana (Chujo, 1935), comb. n., P. nantouensis (Kimoto, 1996) comb. n., and P. yasumatsui (Kimoto, 1969), comb. n. The position of M. excavata Chujo, 1938 in Paleosepharia is confirmed. Lectotypes are designated for M. excavata Chujo, 1938 and M. formosana Chujo, 1935. Generic characters of Paleosepharia are re-evaluated in the context of these nomenclatural changes.
