Erebinae, a subfamily within the family Erebidae, represents one of the largest classification groups in Lepidoptera. This taxonomic group exhibits remarkable ecological diversity and astonishing predator defense adaptations. Erebinae possesses what is presumed to be the most sensitive tympana (hearing organs) among Lepidoptera, allowing them to evade predators such as bats. Furthermore, they have distinctive hindwings, in contrast to their inconspicuous forewings, which they can suddenly expose as a strategy to escape danger from predators. The classification of the subfamily Erebinae is based on molecular studies conducted by Zahiri et al. (2012). However, despite these efforts, there is no single external feature that can reliably identify all Erebinae, and the boundaries of this group remain somewhat unclear. Many specimens have yet to be thoroughly studied, and numerous genera are still awaiting placement within the phylogenetic framework.

Erebidae is one of the most diverse families within Lepidoptera. Erebinae is one of its subfamilies that stands out for having a remarkable diversity, which complicates its taxonomic classification. It exhibits a high degree of global diversity, with many yet-to-be-explored faunal aspects. In this study, we review the historical classification of Erebinae and incorporate the latest molecular phylogenetic analyses alongside traditional morphological groupings. Furthermore, we present a detailed list of Erebine tribes and species found in Korea, highlighting the literature and morphological characteristics employed in grouping genera within these tribes. This study aims to advance our understanding of Erebinae’s complex taxonomy and biodiversity.
