A new species of Horaga Moore (Lepidoptera, Lycaenidae, Lycaeninae, Theclini), with a key to the species of the subtribe Horagina

摘要

A new lycaenid species, Horaga uedai sp. nov., is described from Laos and compared with the closely related species, H. rarasana Sonan. In particular, the wing markings and genitalia of adults of both species are morphologically examined and illustrated. The distribution of the two species is briefly discussed from a biogeographical point of view. A key to the species of the subtribe Horagina is also proposed.
