ウラギンヒョウモン（Argynnis属Fabriciana亜属）2種♀とタイプ標本の形態比較分析

抄録

In the subgenus Fabriciana of the genus Argynnis, three distinct species of Japanese high brown fritillaries are recognized. It has been noted that identifying females of the three species can be particularly challenging. This study focuses on two of the three species, referred to by their Japanese names, Sato Uragin-hyoumon and Yamo Uragin-hyoumon, henceforth denoted as "sato" and "yama" for simplicity. Through discriminant analysis (DA) of morphological traits including wing shape, wing veins, and marking spots, significant differences between the two species were identified. This analysis enabled the discrimination of type series specimens. Specifically, A. addipe kurosawae Matsumura, 1915 from the Hokkaido University Museum was assigned to the species sato. Additionally, examination of seven type females of A. locuples Butler, 1881 from the Natural History Museum (NHM), London revealed a composition of five sato and two yama females. Consequently, A. nagiae Shinkawa et Iwasaki, 2019, previously tentatively assigned as the name-bearing type of yama, can now be confidently positioned within the taxonomy.
