Description.

Male (Prague, Czechia, MR007, MR): Carapace with scattered white setae; cephalic region subrectangular with broadly rounded posterior margin, longer than wide, moderately raised; AME distinctly smaller than PME (AME/PME 0.63), median eyes slightly separated on horizontal axis, slightly overlapping on vertical axis; ALE tubercles absent, PER slightly narrower than AER (PER/AER 0.89), PLE position on carapace 0.39; clypeal hood forms acute angle; fovea moderately deep. Chelicerae contiguous mesally, with lateral boss. Legs with bands of white setae; with row of distal ventral macrosetae on metatarsus I–IV plus additional ventral macrosetae on tibia, metatarsus and tarsus I–IV. Abdomen red dorsally with large dark patches surrounding anterior two pairs of sigilla (Figs 2B, 9A, B, 43 A–D).

Male palp with proximal-distal axis; tegulum bulbous; conductor and embolus together form apical complex making one helical turn; conductor ribbon-like, tip broadly rounded with a notch (Figs 13 A–C, 43I, J, 44 A–F; Řezáč et al. 2008: fig. 5A, D); tegular division longer than embolic division; cymbium with several prolateral macrosetae.

Female (Srbsko, Czechia, MR016, MR): Carapace with scattered white setae; cephalic region subrectangular with broadly rounded posterior margin, longer than wide, moderately raised; AME distinctly smaller than PME (AME/PME 0.63), median eyes slightly overlapping on horizontal and vertical axes; ALE tubercles absent; PER slightly narrower than AER (PER/AER 0.89), PLE position on carapace 0.39; clypeal hood forms acute angle; fovea shallow. Chelicerae contiguous mesally, with lateral boss. Legs with scattered white setae, with row of distal ventral macrosetae on metatarsus I–IV plus additional ventral macrosetae on metatarsus and tarsus III–IV. Abdomen without conspicuous white setae (Figs 2A, 9C, D, 43 E–H).

Epigynum with slit-like atria occupying nearly the total length, anteriomedian part with notch-shaped invagination, anteriolateral margin a curved ridge (Figs 16H, 45A; Řezáč et al. 2008: fig. 4G). Vulva with large, bulbous spermathecal heads anteriorly leading to posterior spermathecae with multiple weakly-differentiated lobes (Fig. 16K; cf. Figs 16L, 45 B–D; Řezáč et al. 2008: fig. 4J).
