Porrhoclubiona bosmansi  sp. n. Figs 1c, e, 2 a–d, j, 3, 4 a–c, 5a, g, 7 d–f, 8 d–f, 9a, 10d

Clubiona vegeta  : Andreeva 1976: 77.


Holotype ♂ and paratype ♂ ( ZMMU) TAJIKISTAN, Khalton area, Dangara Distr, Sanglogh (= Sanglok), Mt. Range, above Shar-Shar Pass, 38°17.937'N, 69°13.598'E, 1700-2060 m, 29 Apr 2015 (Y.M. Marusik), 1♀ ( ZMMU) TAJIKISTAN, Khalton area, environs of Khovaling, Obimazar River, 38°20.940'N, 69°58.194'E, 1413 m, gravely river shore with some bushes, 27 Apr 2015 (Y.M. Marusik).


The specific name is a patronym in honour of our friend and colleague Robert Bosmans (Gent, Belgium) who made significant contributions to the study of the Clubiona genevensis  -group.


Porrhoclubiona bosmansi  sp. n. differs from P. laudata  by having a smaller carapace (1.7-1.77 vs. 2.11), smaller palp (cf. Fig. 10c and Fig. 10d) and thinner tibial apophysis. The new species differs from P. moradmandi  sp. n. by the smaller palps and shorter modified cymbial hairs (cf. Fig. 5a and Fig. 5b), fewer pro- and retro lateral spines on metatarsus III (2-2 vs. 3-3), and inclined anterior edge of the embolic base (vs. almost horizontal, cf. Fig. 10 b’ and Fig. 10 d’). Female of P. bosmansi  sp. n. differs from those of P. moradmandi  sp. n. by the shape of the epigynal fovea, which is more transverse and lacking posterior notch (cf. Fig. 8 a–c, d–f). Females of the two species differ by the shape of the copulatory ducts and relative position of hyaline and sclerotised receptacles: sclerotised receptacles located anterior to the hyaline receptacles in P. bosmansi  sp. n. and posteriorly in P. moradmandi  sp. n. (cf. Fig. 9a and 9b).


Male (holotype-paratype). Total length 3.55-3.63. Carapace 1.71-1.77 long, 1.11-1.29 wide. Abdomen 1.86-1.88 long, 1.23-1.30 wide. Carapace light-brown, cephalic area darker. Labium, maxillae, chelicerae brown. Sternum yellowish. Chelicerae with one prolateral tooth, retrolateral teeth absent.

Leg lengths (paratype).

Leg spination

Abdomen yellow-reddish at dorsal part with dark-reddish cordial mark. Lateral sides of abdomen reddish, ventral side yellowish.

Palp as in Figs 4 a–c, 5a, g, 7 d–f, 10d. Tibial apophysis triangular, wider than long; anterior edge of cymbium almost flat (horizontal, not rounded); setae in cymbial brush not dense, approx. 1/3 of cymbial length; anterior part of tegulum (At) longer than base of embolus (Be); posterior edge (Pb) of the basal part of embolus inclined as well as anterior part of embolic base.

Female. Carapace 2.1 long, 1.43 wide. Abdomen 3.38 long, 2.4 wide. Total length 5.5. Coloration as in males, but somewhat lighter. Chelicerae with 4 prolateral and 3 retrolateral teeth.

Leg lengths

Leg spination

Epigyne as in Figs 8d, e, 9a. Fovea oval, more than twice as wide as long, posterior notch absent; translucent sclerotised receptacles (Sr) spaced by approx. one radius in intact epigyne; hyaline receptacles (Hr) located posterior to sclerotised receptacle; hyaline receptacles 1.3 times larger than sclerotised receptacles; loop of copulatory duct (Dl) directed posteriorly and spaced from each other by approximately one diameter.
