Type species. Clubiona genevensis L. Koch, 1866 from Switzerland. Diagnosis. Distinct from all other clubionids by the cymbium with modified setae retrolaterally (not observed in P. pteronetoides Deeleman-Reinhold, 2001 Fig. 15B ); cymbial base with a tutaculum (Fig. 15B ); tegulum with a tegular groove serving as a conductor (Fig. 15D ); tibia with a strongly reduced prolateral apophysis (Fig. 15A ); subtegulum located posteriorly (Fig. 15C, D ); sperm duct U-shaped, with an additional loop located proximally to embolic base (Fig. 15D ); copulatory openings large, located posteriorly on ventral epigynal plate, united at midline, or separated but close (Fig. 16A, B ); epigynal plate with a somewhat protruded posterior margin (Fig. 16A, B ).

Description. See Marusik and Omelko (2018) and Deeleman-Reinhold (2001) . Comments. Porrhoclubiona is small Clubionidae with a relatively wide body and can be easily separated from Malamatidia , Matidia , and Nusatidia . Porrhoclubiona currently comprises two species groups, the Porrhoclubiona pteronetoides group and the Clubiona genevensis group. The Porrhoclubiona pteronetoides group was established by Deeleman-Reinhold (2001) based on two species endemic to the Oriental realm. The Clubiona genevensis group was formally named by Mikhailov (1992), though in fact it was first recognised by Lohmander (1944) as a subgenus of Microclubiona (currently considered junior synonyms of Clubiona ), and then refined by Bosmans et al. (2017) with eight species from West Palaearctic region. The two groups share almost all of the generic characters listed by Marusik and Omelko (2018) (see diagnosis above); however, Porrhoclubiona pteronetoides group can be differed from the Clubiona genevensis group by have a dorsal abdominal scutum (Fig. 16E, F ) (vs. absent), lack modified setae on the cymbium (Fig. 15B ) (vs. present) in males, and the spermathecae are elongate in females (Fig. 16C, D ) (vs. round).
