Haplodrassus dentifer Bosmans & Abrous  , sp. n.

Figs 30‒40View FIGURES 30–40, 49‒53View FIGURES 49–57, map 2

Types. Holotype ♂, paratypes 1♂ 2♀ from Morocco, Souss-Massa , between Aoulouz and Tallliouine (N30°34’41” W8°3’11”), 600m, stones in steppe, 4.II.1996, J. Van Keer leg.; deposited in RBINSGoogleMaps  .

Etymology. The species name is derived from the Latin noun dens (tooth) and the verb ferre (to wear) and refers to the presence of a tooth at the base of the embolus.

Diagnosis. Haplodrassus dentifer  sp. n. is closely related to H. rufipes  . Males are at once recognized by the presence of a subterminal tooth at the prolateral margin of the embolic apophysis in H. rufipes  ( Figs 131View FIGURES 126–135, 142View FIGURES 136–144), absent in H. dentifer  ( Figs 35View FIGURES 30–40, 51View FIGURES 49–57), females by the converging, gradually narrowing antero-lateral branches of the areola ( Figs 40View FIGURES 30–40, 52View FIGURES 49–57), straight and truncate in H. rufipes  ( Figs 132View FIGURES 126–135, 143View FIGURES 136–144).

Description. Measurements: Male (n=5): Total length 5.6‒9,6 mm; carapace 1.22‒2.02 long, 0.99‒1.58 wide. Female (n=11): Total length 7.6‒9.6 mm; carapace 1.96‒2.44 long, 2.44‒3.12 wide. Colour: Carapace yellowish brown with darkened eye region; chelicerae dark brown; sternum and legs yellowish brown; abdomen grey.

Male palp ( Figs 32‒36View FIGURES 30–40, 49‒51View FIGURES 49–57): Tibia 2.5 times as long as wide, gradually narrowing, slightly widened before the rounded tip ( Figs 33View FIGURES 30–40, 50View FIGURES 49–57); embolic apophysis nearly straight, without denticulations, with pointed tip; base of embolus with strong denticulate keel ( Figs 36View FIGURES 30–40).

Epigyne ( Figs 38‒40View FIGURES 30–40, 52‒53View FIGURES 49–57): Anterior margin nearly as wide as areola; pro-fovea short, less than half the length of the fovea; foveal border marked by a strong medio-lateral tooth, but often obscured by the presence of concretions (compare Figs 39 and 40View FIGURES 30–40).
