(SSTTU); ♀ paratype, 40°–60° slope of Dancizh Mt., spruce stands with moss and lycopodium, in hollows between stones, 48°08’30.1”N 24°32’51.8”E, 09.VII.2012, Gnelitsa leg. (SSTTU); 2♀ paratypes, same data, (VGC); 2♀, Maly Breskul Mt., 48°09’22.6”N 24°31’31.6”E, slope with stones, meadow with juniper, in grass between stones, 13.VII.2012, Gnelitsa leg. (VGC).
Etymology. The species name is taken from the Carpathians, the region of type locality.
Diagnosis. Taranucnus carpaticus n. sp. is most similar to T. bihari Fage, 1931. Males of T. carpaticus n. sp. can be differentiated from those of T. bihari by the following features: carapace length / width 1.68 / 1.37—(1.26 / 1.10 in T. bihari); chelicerae length—width ratio 3.64–(3.75), proximal tooth of its anterior row smaller than other ones (Fig. 12)— (teeth are nearly the same size; Fig. 11), posterior row with three small teeth gradually increasing distally—(posterior row with a small tooth); embolus not or scarcely longer than embolic membrane (Figs 3–6)—(noticeably longer than embolic membrane; Figs 2, 7), distant part of the embolic membrane curved gradually (Figs 1, 3–6)—(turned round sharply; Figs 2, 7), subtegulum with noticeable appendix frontally (Fig. 1)—(appendix on the frontal part not visible; Fig. 2), complex outgrowth of cymbium dilated towards apex “A” or with parallel edges and rounded (Figs 9–10)— (triangular in the apical part “A” and rather pointed; Fig. 8), lateral appendix of cymbium “CLA” (Fig. 6) larger than of T. bihari (Fig. 7). Females of T. carpaticus n. sp. have the cut of the border of the anterior wall of the epigynal cavity (Figs 17–18) not as prominent T. bihari (Fig. 19), (“mucrone” sensu Fage (1931)).
Male (holotype). Total length 3.50; carapace: 1.68 long, 1.37 wide; brown-yellow with brown-yellow-grey margin (Figs 12–14); sternum: 0.88 long, 0.81 wide, caudally extended between coxae IV (Fig. 22), with long thin hairs, yellowgrey with slightly darker margin; posterior median eyes a diameter apart, suffused with black; chelicerae anterior margin with three teeth, basal tooth noticeably shorter than the other ones (Fig. 12); posterior margin with three small teeth, gradually increasing from proximal to apical ones; stridulating files distinct (Fig. 14). Abdomen pale grey with black pattern (Fig. 24). Legs yellow; only the right side legIII completely present; spination: FeI—1d:1l; FeII—1d; FeIII—1d, TiIII—2d:1p:1r; MtIII—1d; position of metatarsal trichobothrium: III—0.18. Palp: see Figs 1, 3–6, 9–10.

Female (paratype). General appearance as in male. Total length 3.68; carapace 1.48 long, 1.22 wide, grey-yellow with border lines with grey (Figs 15, 16); sternum 0.85 long, 0.83 wide, caudally extended between coxae IV, dark yellow-grey (Fig. 23); posterior median eyes a diameter apart; anterior margin of chelicerae distaly with three teeth of equal size, posterior margin with five tiny teeth; stridulating files very thin, indistinct. Abdomen pale grey with black pattern (Fig. 25). Legs yelow; the chaetotaxy of the tibia of the correspondent right and left legs differs: left (right) legs spination: FeI—1d:1p, TiI—2d:2p:3r: 2v (2d:2p:3r: 2v), MtI—2d; FeII—1d, TiII—2d:1p:1r: 1v (2d:2p:1r: 2v), MtII—2d; FeIII—1d, TiIII—2d:1p (2d:1p:1r: 1v), MtIII—2d; TiIV—2d:1p:1r: 1v (2d:2p:2r: 1v), MtIV—2d; position of metatarsal trichobothrium: I—0.21, II—0.23, III—0.23. Epigynum: see Figs 17–18, 20; vulva: see Fig. 21.
