초록

We performed molecular and morphological analyses to determine generic limit of the genus Aulacorthum including several species with controversial taxonomic histories. The sequences of four mitochondrial genes, COI, COII, srRNA and lrRNA, and one nuclear gene, EF1a, implied that Aulacorthum is not monophyletic, with Aulacorthum magnoliae and Aulacorthum nipponicum forming a clade that is not sister to other currently recognized Aulacorthum species. Morphometric analysis based on 20 morphological characters also showed that A. magnoliae and A.nipponicum exhibited morphological characteristics distinct from congeneric species. Based these results, we propose a new genus, Neoaulacorthum ge. n. for A.magnoliae and A.nipponicum.
