Type species.

Aranea lentiginosa C. L. Koch, 1837.

Comments.

The genus belongs to Gnaphosinae, and like all other members of this subfamily has a serrated keel on chelicera. It is easily distinguished from all other Gnaphosinae by long to very long spinnerets (Figs 1c, 4a, 6 a–b, 10 b–c, 11g), the male palp with squarrose tibial apophysis and a heavily sclerotized (non-membranous) and pointed “conductor”. Most of the species have a stylus on embolus (vs. lacking in all other genera).

Distribution.

The genus is known from Spain to South Africa, to western India, with a single, doubtful record of Pterotricha saga ( Dönitz & Strand, 1906) from Japan (most likely belonging to Callilepis Westring, 1874).
