Diagnosis. Haplodrassus securifer sp. n. is closely related to H. macellinus Thorell, 1871 . In males of H. macellinus the tibial apophysis is more elongate and more rounded terminally (fig. 237 versus Figs 147 View FIGURES 145–153 , 163 View FIGURES 162–171 ). The length and shape of the embolic apophysis is more elongate in H. macelllinus than in H. securifer , and as long as the embolus in H. securifer sp. n. ( Figs 149 View FIGURES 145–153 , 162 View FIGURES 162–171 ), much shorter than the embolus in H. macellinus (fig. 236). Females are distinguished by the hood as wide as the areola in H. securifer sp. n. ( Figs 151 View FIGURES 145–153 , 165 View FIGURES 162–171 ), half as wide in H. macellinus ( Figs 238, 239 View FIGURES 232–240 ).

Etymology. The species name is derived from the Latin noun securis (axe) and the verb ferre, to wear, and refers to the shape of the tibial apophysis resembling an axe. It also reminds the species names H. dentifer sp. n. and H. signifer .

Description. Measurements: Male (n= 20): Total length 5.2‒6.5; carapace 2.1‒2.6 long, 1.7‒2.0 wide. Female (n= 10): Total length 6.0‒10.0; carapace 2.8‒2.9 long, 2.0‒2.2 wide. Colour: Carapace chestnut brown with darker eye region; chelicerae dark brown; legs yellowish brown; abdomen grey to pale grey, often dorsally pale grey with a darker grey pattern of stripes and chevrons: anteriorly with 3‒4 pairs of oblique stripes, posteriorly with 5‒6 chevrons; venter pale. Spination: Basal spination but ventral spines on Mt I and prolateral spines on Fe IV mostly missing.

Male palp ( Figs 147‒151 View FIGURES 145–153 , 162‒164 View FIGURES 162–171 ): Tibial apophysis slightly curved, as long as the tibia’s diameter, very asymmetrical, dorsal margin strongly truncate in distal half ( Figs 147 View FIGURES 145–153 , 163 View FIGURES 162–171 ); median apophysis with relatively long hook; embolic apophysis curved a bit at base only, then almost straight, directed anteriorly, terminally pointed ( Figs 149 View FIGURES 145–153 , 164 View FIGURES 162–171 ); embolus hidden by large embolic apophysis.

Epigyne: Epigyne slightly longer than wide, pro-fovea as long as fovea, anterior margin straight, poorly marked ( Figs 151 View FIGURES 145–153 , 165 View FIGURES 162–171 ); fovea somewhat longer than wide, pointed posteriorly; areola semi-circular, with anteromedian angularity; large and rounded lateral pockets, double the size of the receptacles ( Figs 152‒153 View FIGURES 145–153 , 166 View FIGURES 162–171 ).

Distribution. Haplodrassus securifer sp. n. appears to have a large distribution area: Portugal, Spain, Algeria, Morocco, Tunisia, France, Belgium and Italy (map 7). In Algeria, it was recorded in the Central North but also in the Hoggar in the South, in Morocco in the North and in the South, in Spain in Andalucía, in France in the South and in Italy in Puglia, Sardinia and Sicilia. The only record in Belgium is remarkable and is probably an introduction. The species was found on an old slag-heap of charcoal enjoying an exceptional warm microclimate. Some other rare Belgian species were found there, such as Agroecina lineata ( Simon, 1878) and Gnaphosa opaca Herman, 1879 ( Janssen 1994) . Although pitfalls traps were used during two consecutive years, only one male was found.
