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 View FIGURES 11 – 16 )— (teeth are nearly the same size; Fig. 11 View FIGURES 11 – 16 ), 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 View FIGURES 1 – 7 )—(noticeably longer than embolic membrane; Figs 2, 7 View FIGURES 1 – 7 ), distant part of the embolic membrane curved gradually ( Figs 1, 3–6 View FIGURES 1 – 7 )—(turned round sharply; Figs 2, 7 View FIGURES 1 – 7 ), subtegulum with noticeable appendix frontally ( Fig. 1 View FIGURES 1 – 7 )—(appendix on the frontal part not visible; Fig. 2 View FIGURES 1 – 7 ), complex outgrowth of cymbium dilated towards apex “A” or with parallel edges and rounded ( Figs 9–10 View FIGURES 8 – 10 )— (triangular in the apical part “A” and rather pointed; Fig. 8 View FIGURES 8 – 10 ), lateral appendix of cymbium “CLA” ( Fig. 6 View FIGURES 1 – 7 ) larger than of T. bihari ( Fig. 7 View FIGURES 1 – 7 ). Females of T. carpaticus n. sp. have the cut of the border of the anterior wall of the epigynal cavity ( Figs 17–18 View FIGURES 17 – 25 ) not as prominent T. bihari ( Fig. 19 View FIGURES 17 – 25 ), (“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 View FIGURES 11 – 16 ); sternum: 0.88 long, 0.81 wide, caudally extended between coxae IV ( Fig. 22 View FIGURES 17 – 25 ), 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 View FIGURES 11 – 16 ); posterior margin with three small teeth, gradually increasing from proximal to apical ones; stridulating files distinct ( Fig. 14 View FIGURES 11 – 16 ). Abdomen pale grey with black pattern ( Fig. 24 View FIGURES 17 – 25 ). 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 View FIGURES 1 – 7 , 9–10 View FIGURES 8 – 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 View FIGURES 11 – 16 ); sternum 0.85 long, 0.83 wide, caudally extended between coxae IV, dark yellow-grey ( Fig. 23 View FIGURES 17 – 25 ); 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 View FIGURES 17 – 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 View FIGURES 17 – 25 ; vulva: see Fig. 21 View FIGURES 17 – 25 .
