Material examined. Armenia : Vayots Dzor Province : 1♂ 1♀ 2 juv. (ZMMU), env. of Gnishik Vill., 39°40'18"N , 45°17'40"E , ca 2030 m , 11.05.2021 ( Y.M. Marusik ) ; 3♂ 3♀ 6 juv. (ZMMU), Shatin , 39°50'N , 45°19'E , 9.05.2021 ( Y.M. Marusik ) . Diagnosis. For the male, see Beydizade et al. (2018) . The female of D. nakhchivanica is most similar to that of D. collucata Dunin, 1991, a species restricted to southernmost Armenia. The two species have tips of receptacular lateral edges ( Rl ) bent posteriorly (vs not bent or directed anteriorly in other species) and have membranous posterior diverticula ( Pd ) unknown in other Dysdera species in the Caucasus or adjacent regions. The female of D. nakhchivanica differs from that of D. collucata by the relatively longer (i.e., three times wider than long) and distinctly trapezoidal dorsal arch ( Da ). Description. Male. See Beydizade et al. (2018) . Female. Habitus as in Fig. 1B . Total length 11.87. Carapace 4.12 long, 3.10 wide. Eye sizes: AME 0.16, PME 0.15, PLE 0.17. Carapace and chelicerae dark reddish; carapace slightly lighter posteriorly. Sternum, labium, and maxillae reddish. Legs yellowish orange. Abdomen light beige, without any pattern. Spinnerets uniformly beige. Measurements of legs: I: 12.10 (3.41, 2.20, 3.00, 2.90, 0.59), II: 10.90 (3.06, 1.93, 2.60, 2.65, 0.66), III: 7.87 (2.27, 1.25, 1.67, 2.05, 0.63), IV: 11.05 (3.24, 1.65, 2.43, 2.96, 0.77). Spination: I, II: no spines. III: Ti: 2pl, 2rl, 2v; Mt: 3pl, 2rl, 6v. IV: Fe: 3d; Ti: 2rl, 2v; Mt: 3pl, 3rl, 6v. Endogyne as in Fig. 7 ; receptacle ( Re ) with posteriorly bent lateral edges ( Rl ), ca 8 times longer than wide and as wide as transverse bar ( Tb ); dorsal arch ( Da ) ca 2.5 times wider than long, with rounded anterior edges; transverse bar ( Tb ) long and thin, ca 15 times longer than wide; posteriorly with pair of diverticula ( Pd ). Note. The holotype of D. nakhchivanica has four teeth on the median process ( Mp ), while Armenian specimens have 5-7. We have tentatively considered this as an intraspecific variation. Certain variations in the male palp, some of which depend on the photography angle, are illustrated in Figs 4A and 6A-D . Figure 4. Male of Dysdera nakhchivanica , bulb.
