Etymology. Simon (1909) obviously gave this name as a reference to the speckled abdomen of the species.

Diagnosis. Haplodrassus nigroscriptus  can at once be recognized by the speckled abdomen ( Figs 67, 68View FIGURES 67–76). It is further remarkable in the male by the presence of abundant, strong spines on the cymbium (fig. 71), in the female by the more than 20 thick spines on the female palpal tarsus (fig. 73). The species can therefore not be confused with any other Haplodrassus  species. Males can further be distinguished by the relatively small embolic apophysis ( Figs 70View FIGURES 67–76, 83View FIGURES 77–86), females by the rounded anterior hood and the fovea with nearly parallel margins ( Figs 74View FIGURES 67–76, 85View FIGURES 77–86).

Remarks. There are no differences in the copulatory organs of the syntypes males and females of H. nigroscriptus nigroscriptus  and H. nigroscriptus deminutus  . They were collected at the same locality. Simon (1909) distinguished the two subspecies only by differences in size, colour and spinulation, but these are no diagnostic characters. We consider them synonyms.

Description. Measurements: Male (n=8): total length 5.6‒7.2; carapace 2.68‒3.76 long, 2.12‒2.72 wide. Female (n=9): total length 4.8‒10.4; carapace 2.40‒4.22 long, 1.64‒3.32 wide.

Colour: Carapace yellowish brown, cephalic part brown; chelicerae dark brown; sternum yellowish brown with darkened margins; legs pale yellowish brown; abdomen pale grey speckled with abundant, small dark grey spots or short stripes, rarely not present ( Figs 67, 68View FIGURES 67–76). Spinulation: General pattern.

Male palp: Tibia with 3 distinct spines at prolateral side; cymbium dorsally with about 20, scattered strong spines (fig. 71); tibial apophysis elongated, slightly curved with truncate tip ( Figs 72View FIGURES 67–76, 84View FIGURES 77–86); embolic apophysis narrow and elongated, small relatively to the tegulum, without denticles and with rounded tip ( Figs 70View FIGURES 67–76, 83View FIGURES 77–86).

Epigyne: Almost twice as long as wide, with semi-circular anterior hood ( Figs 74View FIGURES 67–76, 85View FIGURES 77–86); fovea with nearly parallel margins, without denticles; lateral pockets semi-circular ( Figs 75‒76View FIGURES 67–76, 86View FIGURES 77–86).
