Figs 6View FIGURE 6 A–G, 7A –F

Etymology. The species is named after Till Lindemann, the lead vocalist and lyricist of the band “Rammstein”.

Diagnosis. The new species differs from all congeners occurring in the Palaearctic by the pale colouration with a distinct dark abdominal pattern (vs. dark colouration with pale abdominal pattern). Except for P. labialis Paik, 1991  , the female of P. lindemanni  sp. nov. differs from all other species where the structure of the endogyne has the anterior (secondary) receptacles each with a thin stalk (ca. ¼ of receptacle diameter vs. distinct stalk lacking), the globular posterior (primary) receptacles each with a long gland located laterally and broad copulatory ducts (vs. posterior receptacles not globular, or glands not located laterally, and copulatory ducts lacking or indistinct). The only species likely to be confused with P. lindemanni  sp. nov. is P. labialis  . Phrurolithus labialis  has longer stalks of the anterior receptacles, the receptacles are more widely spaced (cf. Figs 7D, EView FIGURE 7 and figs 19–25 in Paik 1991), and the fovea has a pair of distinct anterior pockets (vs. fovea without distinct margins). Male unknown.

Description. Female (Holotype). Total length 2.68–2.78. Carapace 1.17–1.20 long, 0.87–0.94 wide. Carapace uniformly pale coloured, evenly covered with light dense setae ( Fig. 6CView FIGURE 6). Sternum with distinct pattern formed by tissues lying below integument: median stripe and radial stripes directed to spaces between coxa. Chelicerae with 3 promarginal and 2 retromarginal teeth.

Abdomen yellowish, with distinct dorsal pattern, venter with two dark median stripes. Postero-lateral margins of epigastric fold sclerotized ( Fig. 6GView FIGURE 6). Legs uniformly coloured as in carapace, covered with whitish setae. Leg lengths as shown in Table 5. Legs I-II equipped with numerous ventral spines ( Table 6).

Epigyne as in Figs 7View FIGURE 7 A–F; plate wider than long, fovea lacking distinct margins and having separate copulatory openings; pair of rounded anterior receptacles visible through integument. Endogyne with large mushroom-shaped anterior receptacles with short stalks; copulatory ducts as wide and as long as diameter of posterior receptacles; posterior receptacles separated by 2 diameters, with long glands located laterally and directed anteriorly, glands longer than diameter of receptacle; fertilization ducts divergent and located near glands on anterior part of posterior receptacle.

Type material. Holotype ♀ and 4♀ paratypes: RUSSIA: Maritime Province: Lazo Village , ca. 43°23’N, 133°55’E, leg. Y.N. Sundukov, 15–20.IV.2002 ( ZMMU).GoogleMaps 

Paratypes: RUSSIA: Maritime Province: Khasan District, env of Andreevka Village, ca. 42°39’N, 131°08’E, leg. S. Koponen, 11–15.VIII.1998, 1♀ ( ZMUT);GoogleMaps  Lazovskii Reserve , Korpad’ Camp, 43°16'N, 134°08'E, leg. Y.N Sundukov, 19–24.V.2004, 1♀ ( ZMMU)GoogleMaps  .

Note. All specimens studied have the epigynal fovea covered with mating plugs.

Distribution. This species was found in widely separated localities in the southern part of the Maritime Province ( Fig. 8View FIGURE 8).
