Phycosoma O. P.- Cambridge, 1879

Phycosoma O. P.- Cambridge, 1879: 692. Trigonobothrys Simon, 1889: 231 .

Diagnosis. Phycosoma is separated from other Hadrotarsinae by the following characters: male carapace often very high, almost cylindrical, with deep dorsal grooves when viewed from above (Figs 1, 6, 9, 15, 20); female carapace, if high, only anteriorly. Eye region often projecting beyond clypeus (Figs 1, 6, 9, 15, 20). Male palp with a median apophysis, a small conductor and a small embolus (Figs 2, 7, 10, 16, 21). Epigynum with a small scape (Figs 4, 13, 18, 23). Most species without colulus (except P. m u s t e l i n u m (Simon, 1889) with a colulus).

Comments. Fitzgerald & Sirvid (2004) gave the diagnosis and description of Phycosoma by examining the type species P. oecobioides O. P.- Cambridge, 1879. The generic diagnosis given here is based in part on Yoshida’s (2002) diagnosis of Trigonobothrys and Fitzgerald & Sirvid’s (2004) diagnosis of Phycosoma . P. stellaris, P. h a na, P. labialis, P. hainanensis and P. s i n i c a were originally placed in the genus Dipoena . The characters of these species fit the diagnosis and circumscription of the genus Phycosoma, and we transfer these species to the genus Phycosoma . We believe that revisionary work on the genus Dipoena will likely reveal more species that should be transferred to Phycosoma .
