Holotype specimen of Plebejus argus seoki Shirôzu & Sibatani, 1943 from Jeju Island, Korea

Abstract

Plebejus argus seoki Shirôzu & Sibatani, 1943 (Lepidoptera: Lycaenidae) was described from Jeju Island, Korea, based on specimens collected by Du-Myung Seok. Shirôzu and Sibatani (1943) incorrectly indicated the holotype of this subspecies in their original description. To avoid taxonomic confusion, we illustrate the true holotype deposited at Kyushu University for the first time.
