The spider, W. okinawensis (Tanaka), of the genus Wadicosa Zyuzin (Araneae: Lycosidae) in Japan.

Abstract

A lycosid spider, Pardosa okinawensis Tanaka 1985, which is distributed in the Southwest Islands (Okinawa Is., Kumejima Is., and Amami-Oshima Is.), Japan, was newly found to be a member of the genus Wadicosa Zyuzin. This species resembles Wadicosa venatrix from Europe and China but differs from it by having an embolus with non-twisted tip on the male palp.
