Revision of the genus Aseptis McDunnough (Lepidoptera Noctuidae Noctuinae Xylenini) with a description of two new genera Paraseptis and Viridiseptis

摘要

The genus Aseptis McDunnough (Lepidoptera, Noctuidae, Noctuinae, Xylenini, Xylenina) is revised to include 15 species based on morphological and molecular data. Several new synonymies are introduced. In addition, two genera are described because of significant morphological differences from Aseptis: Paraseptis >gen. n., and Viridiseptis >gen. n., resulting in the new combinations Paraseptis adnixa (Grote), >comb. n., and Viridiseptis marina (Grote), >comb. n. Although this work is primarily based on morphological data, DNA sequence data for the 658-base pair “barcode” segment of the mitochondrial gene for subunit 1 of cytochrome c oxidase was used as a secondary support for taxonomic changes within Aseptis and for the two new genera. Our work should provide clarity and stability in a previously difficult genus.
