Comparative material.
Haplodrassus pugnans
(Simon, 1880): RUSSIA, Magadan Area: 1 ♂, 3 ♀♀ (ISEA,

Distr., env. Sibit-Tyellakh, Aborigen Field Station, Betula, 12-22.06.1983, A.V. Avershin.
Diagnosis.
Haplodrassus bohemicus
is most similar to
Haplodrassus pugnans
(Simon, 1880),
Haplodrassus signifer
(C.L. Koch, 1839) and
Haplodrassus pseudosignifer
Marusiket al. 1996, but differs: 1) by the shape of RTA having a
"step"
-like dorsal margin (RTA dorsal margin without
"step"
in
Haplodrassus pugnans
,
Haplodrassus signifer
and
Haplodrassus pseudosignifer
); 2) by the apically directed embolus lacking a tooth (retrolaterally directed embolus with a tooth in
Haplodrassus pugnans
,
Haplodrassus signifer
and
Haplodrassus pseudosignifer
); 3) by the outlines of epigynal sclerites and relative proportions of the epigynal fovea (cf. Figs 10, 12 and 13, 75, 78).
Description.
Male measurements (n = 5). Total length 5.8-7.5 (6.7); carapace 2.7-3.2 (3.0) long, 2.0-2.6 (2.3) wide. Diameters of eyes and distances between them: AM 0.10-0.15 (0.12), AL 0.10-0.16 (0.13), PM 0.15-0.22 (0.19), PL 0.10-0.14 (0.12), AM-AM 0.09-0.12 (0.10), AM-AL 0.03-0.04 (0.04), PM-PM 0.03-0.04 (0.03), PM-PL 0.12-0.16 (0.14), AM-PM 0.12-0.18 (0.15), AL-PL 0.10-0.16 (0.14). Distances between anterior eyes and margin of clypeus: AM-clypeus 0.18-0.22 (0.20), AL-clypeus 0.10-0.18 (0.15).

Length of palp segments: femur 1.0-1.2 (1.1), patella 0.4-0.5 (0.5), tibia 0.3-0.5 (0.4), tarsus 1.0-1.2 (1.0). Cheliceral teeth: anterior - 2 (little; proximal tooth connected with keel of cheliceral groove), posterior - 2. Abdomen 2.9-4.0 (3.6) long, 1.8-2.2 (2.0) wide. Scutum is absent. Basal segment of anterior (inferior) spinnerets 0.5-0.6 (0.6) long. Coloration light brown, as in most
Haplodrassus
species.
Palp as in Figs 1-6. RTA with a
"step"
(St) on the promargin, terminal apophysis almost straight, without distinct ridge, embolus slightly twisted and lacks a tooth.
Female measurements (n = 2). Total length 7.8-8.0; carapace 2.7-3.5 long, 2.0-2.7 wide. Abdomen 4.3-5.1 long, 2.7-3.1 wide. Coloration light brown, as in most
Haplodrassus
species.
Epigyne as in Figs 10-12. Lateral pockets long, sub-parallel, spermathecae globular. Fovea of epigyne without narrow longitudinal groove.
