Nitidulid beetles of the genus Aethina Erichson, 1843 are a well-known group as harmful to agricultural and apicultural industry, especially including A. tumida, an American small hive beetle, which is a beekeeping pest.
The world-widespread genus Aethina, within subfamily Nitidulinae and family Nitidulidae, is presented 5 subgenera and 28 species in Palaearctic region. Until now, 2 subgenera, Aethina s. str. and Aethina (Circopes), and 3 species, A. (A.) flavicollis, A. (A.) inconspicua and A. (C.) suturallis, have been recorded in Korea, and we added one more species, A. (A.) maculicollis as a newly recorded species. The larvae of A. (A.) maculicollis have been reported as pests of mulberry fruits in Japan.
In this study, we report the taxonomic key to the genus Aethina of Korea, and morphological description of A. (A.) maculicollis.
