A series of specimens with some differences in wing patterns and male genitalia from different localities is recognized as Halpe paupera Devyatkin, 2002 by comparing the COI gene sequences. The morphological variability in male is discussed and illustrated. The intraspecific variation of the female of H. paupera walthewi Devyatkin, 2002 from the type locality is elucidated, and hence this subspecies is considered a synonym of H. paupera paupera. A distribution map and some bionomic information of the species are provided.
