Diagnosis. This species is easily distinguished from other Haplodrassus species of the Maghreb, in the male by the 2 blunt, widely separated terminal teeth of the embolic apophysis ( Figs 62 View FIGURES 58–66 , 79 View FIGURES 77–86 ), in the female by the narrow fovea, the hood being 3 times as wide as the fovea ( Figs 64 View FIGURES 58–66 , 81 View FIGURES 77–86 ).

Etymology. The species is dedicated to our friend Lynda Beladjal, in recognition of her precious aid during this study.

Description. Measurements: Male (n=10): total length 2.9‒5.7; carapace 1.4‒2.7 long, 0.9‒1.6 wide. Female (n=10): total length 3.7‒6.4; carapace 1.7‒2.7 long, 1.3‒1.9 wide. Colour: Carapace yellowish brown, cephalic part slightly darkened; legs yellowish brown; abdomen pale grey, rarely with indications of whitish chevrons. Spination: General pattern.

Male palp ( Figs 60‒63 View FIGURES 58–66 , 77‒80 View FIGURES 77–86 ): Tibial apophysis as long as the tibia’s diameter, gradually narrowing, terminally widened and asymmetric; embolic apophysis with parallel margins, slightly bent, terminally with two blunt teeth.

Epigyne ( Figs 64‒66 View FIGURES 58–66 , 81‒82 View FIGURES 77–86 ): Longer than wide (ratio 1:1.5), pro-fovea very narrow; fovea elongated, narrow anteriorly, dilated in the posterior half; lateral pockets oval, with small lateral pouch.

Remark. The following material possibly belongs to H. lyndae sp. n., but the capture of males should confirm this: ITALY, Sicilia, Terrasini, Riserva Naturale Orientata Capo Rama (N38°8'22” E13°3'38”), 2♀, pitfalls in grassland, 14‒ 24.IV.2012, C. Cusimano leg. (MCSNB).

Ecology. The species is common in the Cedrus and Quercus forests at higher altitudes of Algeria and Morocco. Males were collected from November to May, females from December to June.

Distribution. Central and North Morocco, North Algeria, Central and South Spain and possibly Italy (see above; map 2). It is remarkable the species is present in some Algerian stations of high altitudes (Atlas Blidéen, Aurès Massif, Djébel Sénalba), but absent from others (Massif du Djurdjura, Djébel Ouarsenis and Djébel Babor), where also collections were made at regular intervals.
