Figs 172‒180 View FIGURES 172–180 , 190‒193 View FIGURES 190–197 , map 4

Types : Holotype ♂, paratype ♀ from Morocco, Fès-Meknès, Sidi Harazem (N34°1’38” W4°53’00”), 250m, pitfalls in wheat fields, 23.VI.1997, S. Boksch leg.; deposited in RBINS GoogleMaps .

Etymology. The species name refers to the triangular shape of the fovea.

Diagnosis. This species is easily distinguished from all other species by the J-shaped embolic apophysis ( Figs 175 View FIGURES 172–180 , 190 View FIGURES 190–197 ) in the male and the triangular fovea in the female ( Figs 178 View FIGURES 172–180 , 192 View FIGURES 190–197 ).

Description. Measurements: Male (n=2): Total length 2.9‒3.1; carapace 1.23‒1.46 long, 0.94‒1.12 wide. Female (n=2): Total length 3.1‒4.8; carapace 1.31‒1.60 long, 1.01‒1.26 wide.

Colour: The type material is decoulored, with pale yellowish-brown carapace and legs and abdomen nearly white. In the recently collected male from Tunisia, the carapace has the thoracic part yellowish brown, the cephalic part brown, the foveal region and radiating striae greyish, the legs yellowish brown and the abdomen grey with a row of paired chevrons in its distal two third. Spinulation: General pattern, but femora I without prolateral spine.

Male palp ( Figs 174‒177 View FIGURES 172–180 , 190‒191 View FIGURES 190–197 ): Tibial apophysis as long as the tibia’s diameter, terminally truncate, top rounded at retrolateral side, angular at proventral side; embolic apophysis very peculiar, J-shaped; embolus nearly semi-circular;

Epigyne ( Figs 178‒180 View FIGURES 172–180 , 192‒193 View FIGURES 190–197 ): Hood and pro-fovea much wider than fovea; fovea triangular, much narrower than pro-fovea; areola oblique; lateral pockets with some basal pouches; receptacles separated by 0.25 diameters.
