Abstract

Alloclubionoides grandivulva (Yaginuma 1969) (Araneae: Coelotidae) is redescribed on the basis of topotypical specimens collected from Tsushima Islands, Nagasaki Pref. Kyushu, Japan. Its male is described for the first time and the female internal genitalia is also illustrated for the first time. The male of the species is similar to other Alloclubionoides spiders in having a broad embolus and lacking a patellar apophysis, but only A. grandivulva has a huge extended tegulum.
