Filistata maracandica – Charitonov 1969: 66 (subad. ♀ ). Zaitunia maracandica – Zonstein 1990: 50 (transfer from Filistata ). 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 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 E–J) and from Z. wunderlichi sp. nov. by the longer median receptacles (which are shorter in the latter species; cf. Fig. 33 A–B, D).

Female (Kitab) HABITUS. See Fig. 38 C. BODY LENGTH. 4.33. COLOUR. As in male, but abdomen dorsally and carapace margins are somewhat darker. CARAPACE ( Fig. 42 H). 1.62 long, 1.34 wide. EYES. AME 0.07, ALE 0.13, PLE 0.11, PME 0.08, AME–AME 0.08. ENDOGYNE ( 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 A–D). Ecology This species occurs in various habitats from foothill deserts, steppes and shrubs to open Juniperus forest in the middle mountain belt. Distribution Uzbekistan and southern Kazakhstan ( Fig. 49 ).
