A new subspecies of Avitta fasciosa Moore, 1882 (Lepidoptera, Erebidae) from Korea

Background The genus Avitta Walker is a quite well-known taxon due to the commitment of previous cladistic research, which was considered in terms of biogeography and included a number species (13 valid species and two undescribed female-based species). Given that there are 18 named species, Holloway's work is significant not only from a biogeographic perspective, but also from a taxonomic and phylogenetic standpoint. New information In this study, we recorded a new subspecies, Avitta fasciosa koreana ssp. nov., found on a southern island of Korea, with illustrations and genital features. This is not only just a recording, but also a demonstration that the moth species’ samples, which are generally considered tropical species found in East Asia, can be a separate population or species, but not just the results of migration.
