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).
