Haplodrassus dentifer Bosmans & Abrous View in CoL , sp. n.

Figs 30‒40 View FIGURES 30–40 , 49‒53 View 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 RBINS GoogleMaps .

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 131 View FIGURES 126–135 , 142 View FIGURES 136–144 ), absent in H. dentifer ( Figs 35 View FIGURES 30–40 , 51 View FIGURES 49–57 ), females by the converging, gradually narrowing antero-lateral branches of the areola ( Figs 40 View FIGURES 30–40 , 52 View FIGURES 49–57 ), straight and truncate in H. rufipes ( Figs 132 View FIGURES 126–135 , 143 View 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 32‒36 View FIGURES 30–40 , 49‒51 View FIGURES 49–57 ): Tibia 2.5 times as long as wide, gradually narrowing, slightly widened before the rounded tip ( Figs 33 View FIGURES 30–40 , 50 View FIGURES 49–57 ); embolic apophysis nearly straight, without denticulations, with pointed tip; base of embolus with strong denticulate keel ( Figs 36 View FIGURES 30–40 ).

Epigyne ( Figs 38‒40 View FIGURES 30–40 , 52‒53 View 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 40 View FIGURES 30–40 ).
