Notes on Several Japanese Species of Iwogumoa and Coelotes (Araneae: Agelenidae: Coelotinae)

抄録

Iwogumoa songminjae (Paik and Yaginuma in Paik et al., 1969) is recorded for the first time from Japan on the basis of specimens collected in the Tsushima Islands, Kyushu and previously identified as I. insidiosa (L. Koch, 1878). The relationships among the Japanese species of Iwogumoa Kishida, 1955 are analyzed using mitochondrial cytochrome c oxidase subunit I with various Japanese species of Coelotes Blackwall, 1841 sensu lato as the outgroup. A new synonym is proposed through a comparison of morphological characteristics and the results of our molecular analysis: Coelotes iyoensis Nishikawa, 2009 (known only from the male) is a junior synonym of Coelotes mohrii Nishikawa, 2009 (known only from the female).
