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

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 Laboissière, 1936: P. amiana (Chûjô, 1962), comb. n., P. formosana (Chûjô, 1935), comb. n., P. nantouensis (Kimoto, 1996) comb. n., and P. yasumatsui (Kimoto, 1969), comb. n. The position of M. excavata Chûjô, 1938 in Paleosepharia is confirmed. Lectotypes are designated for M. excavata Chûjô, 1938 and M. formosana Chûjô, 1935. Generic characters of Paleosepharia are re-evaluated in the context of these nomenclatural changes.
