【 摘 要 】

References(8)Cited-By(1)A new species of the genus Paratheuma (Agelenidae) is described from the coast of Awase, Okinawa City, Okinawajima Island, Japan under the name, Paratheuma awasensis sp. nov. The aspect and color of the bodies of both the sexes of this new species resemble those of Paratheuma shirahamaensis (Oi 1960) and P. insulana (Banks 1902) hitherto recorded from Japan, but is clearly distinguished not only from these Japanese species but also from all the known species of the genus by the shape of distal processes of male palpal conductor, the shape of epigynum and female genitalia, the number of marginal teeth of cheliceral fang furrow, and the size of body. Spiders of the new species were collected from underside of holey coral stones on tidal flats of the coast of Awase, Okinawa City. They weave retreats with a sheet web in the cavities of stones.
