Comparative material

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.
Distribution
Czech Republic, Macedonia, Greece, Ukraine (Nikolaev, Kherson, Donetsk Areas, Crimea), Russia (Rostov and Stavropol Areas, Kalmykya, Dagestan) (Miller and Buchar 1977[1]; Ponomarev and Tsvetkov 2006[3]; Stefanovska et al. 2008[2]; Ponomarev et al. 2011[4]; present data).
Comments
Haplodrassus bohemicus is a new species record for the Crimean fauna.
Habitats
Meadows, steppes and sand dunes.
Phenology
♂♀ – V-VI. In Crimea the peak activity of adults occurs in May.
