Newly-recorded species of the genus Atkinsonia Stainton, 1859 (Lepidoptera, Stathmopodidae) from Korea with checklist

Background The genus Atkinsonia in the family Stathmopodidae comprises 13 species described worldwide and only one is recorded from the Korean Peninsula. Despite this low species richness, the genus shows broad ecological diversity at the larval stage, ranging from phytophagy to carnivory, which supports the need for a comprehensive taxonomic study. New information We report Atkinsonia beijingana as a newly-recorded species from the Korean Peninsula. We describe the adult morphology and genitalia. A worldwide checklist of Atkinsonia species and their distributions is also provided to improve understanding of the genus.
