ウラギンヒョウモン（Argynnis属Fabriciana亜属）3種♂とタイプ標本の形態比較分析

抄録

Recent genetic analysis has revealed the presence of three separate species among the Japanese high brown fritillaries which constitute the subgenus Fabriciana of the genus Argynnis. The Japanese names for them are Sato uragin-hyoumon(Sato Fritillary), Yama uragin-hyoumon(Yama Fritillary), and Hime uragin-hyoumon(Hime Fritillary), and in this paper I use sato, yama, and hime to denote the three species for the sake of simplicity. As genetically identified specimens were accumulated, I was able to undertake morphological analyses of sato-, yama-, and hime-identified specimens and categorize the type series specimens, using discriminant analysis and principal component analysis. As results, I show that the pallescens Butler, 1873 types belong to hime, and that the locuples Butler, 1881 types are a mixture of sato and yama. We should use the scientific name A. pallescens for the hime-group whose habitat is limited to the southern part of Oshima peninsula in Hokkaido. The scientific name A. locuples is here stabilized to apply to the sato-group by the designation of the appropriate male specimen in the Natural History Museum, London(NHM). For the yama-group, the name A. nagiae Shinkawa et Iwasaki, 2019 remains at present appropriate, although we found two males of this species in the type series of A. locuples in the NHM, London, and A. addipe kurosawae, 1915, whose identity has not yet been determined, might also be identified as belonging to the yama-group in the future.
