Figs 41‒48 , 54‒57 , map 3

Types: Holotype ♂, paratypes 2♀ from Algeria, Naama, Mecheria, Coll. Simon 6294 ( MNHN AR15688 ); deposited in MNHN .

Etymology. The name is a noun in apposition and refers to the shape of the vulva which is distinctly longer than wide.

Diagnosis. Males of Haplodrassus longivulva sp. n. differ from other species by the absence of teeth on the slightly sigmoid embolic apophysis ( Figs 45 , 54 ) and by the gradually narrowing tibial apophysis with subterminal concavity ( Figs 43 , 55 ). Females are much easier distinguished by the elongated epigyne with large anterior hood ( Figs 47 , 56 ).

Description. Measurements: Male (n=2): total length 2.5‒3.6; carapace 1.53‒1.94 long, 0.86‒1.14 wide. Female (n=5): total length 4.0‒6.6; carapace 1.44‒2.79 long, 0.96‒1.88 wide. Colour (based on recently collected material): Carapace pale yellowish, cephalic part brown to reddish brown, less so in females; chelicerae reddish brown; sternum yellowish red in male, pale yellowish in female; legs pale yellowish grey; abdomen pale grey.

Male palp ( Figs 43‒46 , 54‒55 ): Tibial apophysis short, ventral margin straight, dorsal margin with small subterminal concavity at base, terminally slightly widening and bluntly pointed; embolic apophysis slightly sigmoid, with narrow base, shorter than embolus, terminally with rounded tip.

Epigyne ( Figs 47‒48 , 56‒57 ): Distinctly longer than wide (ratio 1.4‒1.6), anteriorly with marked hood; profovea and fovea elongated, fovea rectangular, anterolaterally with an oblique groove continuing in the pro-fovea; lateral pockets reniform, with lateral chambers.

Ecology. The species was found in steppe vegetation as well as in dry Quercus forest. Males were collected in December and February, females in December and April.

Distribution. Central and South Morocco, NW Algeria (map 3).
