Diagnosis

In the structure of the bulb, males of Z. maracandica resemble Z. ferghanensis sp. nov. but differ by the shape of the palpal tibia, which is considerably more swollen, with thickened setae, as well as by the shape of the vestigial embolic keel, which terminates more gently than in Z. ferghanensis sp. nov. (cf. Figs 35 View Fig. 35 A–D, 37A–C). In the structure of the endogyne, Z. maracandica is similar to Z. ferghanensis sp. nov. and Z. wunderlichi sp. nov., but differs from these species by the shape of the median receptacles, which are subequal to the lateral pair (by contrast, in Z. ferghanensis sp. nov. the lateral receptacles are largest, cf. Fig. 38 View Fig. 38 E–J) and from Z. wunderlichi sp. nov. by the longer median receptacles (which are shorter in the latter species; cf. Fig. 33 View Fig. 33 A–B, D).

Female (Kitab)

HABITUS. See Fig. 38 View Fig. 38 C.

BODY LENGTH. 4.33.

COLOUR. As in male, but abdomen dorsally and carapace margins are somewhat darker.

CARAPACE ( Fig. 42 View Fig. 42 H). 1.62 long, 1.34 wide.

ENDOGYNE ( Fig. 38 View Fig. 38 E–I). All receptacles with corrugated stems, equally spaced; median receptacles clublike, heads separated by 1.6 diameters, shorter than lateral; lateral receptacles conical, with wide bases, slightly bent mesally in the middle part, converging; gland pores evenly distributed on both pairs of receptacles.

Variation

Carapace length in females varies from 1.53 to 2.05; spiders may have darker marks and fasciae on the carapace, legs and abdomen, or these marks may be almost completely absent on the pale background (cf. Fig. 38 View Fig. 38 A–D).

Ecology

This species occurs in various habitats from foothill deserts, steppes and shrubs to open Juniperus forest in the middle mountain belt.
