Diagnosis.
Male palp of D. caspica is most similar to that of D. transcaspica , but differs by the relatively shorter psembolus (Ps) (i.e. length/width ratio ca. 5, vs. 5.4) and the presence of a membranous outgrowth (Mo). Female of D. caspica differs from that of D. transcaspica by the relatively wider anterior diverticulum (Ad) (i.e. almost twice broader than long, vs. 1.5 times broader than long). Males of the two species differ also in spination (i.e. 1 spine on metatarsus III and 2 spines on leg IV in D. caspica , vs. 2 spines on metatarsus III and 3 spines on leg IV).
Description.
Male. Habitus as in Fig. 1A-C View Figure 1 . Total length 3.91. Carapace 1.62 long, 1.26 wide. Eye sizes: AME 0.07, PME 0.08, PLE 0.08. Carapace, sternum, chelicerae, labium and maxillae light reddish. Legs yellowish orange. Abdomen light beige, without any pattern. Spinnerets uniformly beige. Measurements of legs: I: 4.14 (1.23, 0.76, 0.89, 0.84, 0.42), II: 3.68 (1.10, 0.67, 0.78, 0.76, 0.37), III: 2.89 (0.81, 0.51, 0.53, 0.76, 0.28), IV: 3.90 (1.10, 0.61, 0.86, 0.97, 0.36). Spination: III: Ti: 1pl, 1v; Mt: 1pl. IV: Ti: 1pl; Mt: 1pl.
Palp as in Fig. 2A-C View Figure 2 ; tibia twice longer than wide, slightly shorter than cymbium; bulb ca. 3 times longer than wide, tegular part ca. 2 times longer than wide; psembolus ca. as long as tegular part, margins almost parallel, stylus short, shorter than width of psembolus; middle part of bulb with triangular membranous outgrowth (Mo).
Female. Habitus as in Fig. 1D-F View Figure 1 . Total length 5.44. Carapace 1.83 long, 1.36 wide. Eye sizes: AME 0.11, PME 0.06, PLE 0.05. Colouration and spination as in male. Measurements of legs: I: 6.88 (1.96, 1.07, 1.53, 1.73, 0.59), II: 6.05 (1.69, 1.13, 1.34, 1.37, 0.52), III: 4.83 (1.38, 0.84, 0.84, 1.27, 0.50), IV: 6.69 (1.81, 1.29, 1.48, 1.53, 0.58).
Endogyne as in Fig. 3A-F View Figure 3 ; dumbbell-shaped ‘spermatheca’ well visible through integument; anterior diverticulum (Ad) almost 2 times broader than long, heads of spermatheca (Hs) globular, spaced by ca. 2.5 diameters.
Habitats.
A xerophilous species that inhabits wormwood ( Artemisia absinthium L.) and ephemeroid semi-deserts and can be found under stones, in soil cracks and within rodent burrows ( Dunin 1992).
Distribution.
Azerbaijan (Baku, Ganja and Goygol), North Caucasus (Dagestan) (Fig. 8 View Figure 8 ).
