22 (4) - Pages 709-716Sinopesa kumensis n. sp. (Arachnida, Araneae, Nemesiidae) is described from Kume-jima, an island West of Okinawa, Japan. Its male embolus is cork-screw-shaped, the female receptacula bilobed. Compared to S. maculata Raven & Schwendinger, 1995 and S. guangxi Raven & Schwendinger, 1995 from South-East Asia, the median spinnerets are present. For this reason the diagnosis of the genus Sinopesa requires emendation.
Araneae, Nemesiidae, new species, Ryukyu Islands, Japan.
