Redescription of Erebia scoparia doii Nakahara, 1926 (Lepidoptera: Nymphalidae: Satyrinae)

Abstract

The subspecies Erebia scoparia doii Nakahara, 1926 described from the Kuril Islands is one of the poorly studied taxa of butterflies. The images of the external morphology and the male genitalia of this taxon are not freely available to researchers that causes difficulties during ecological and biogeographic studies, as well as various environmental protection measures. In this paper, we present a redescription of Erebia scoparia doii Nakahara, 1926 and illustrate the male genitalia and the external morphology of both sexes based on the topotypes from Kunashir Island. Also, we provide DNA sequence data of this subspecies for the first time. In addition, Erebia scoparia expleta Churkin, 2005 syn. nov. is considered here as a junior synonym of the nominotypical subspecies.
