Diagnosis

By the structure of the bulb, Z. martynovae resembles Z. spinimana sp. nov., but differs from it and all other male congeners by the long and flattened corkscrew-shaped embolus ( Figs 25 A–D, 43F). Females are easily distinguished from all other congeners due to their large and swollen median receptacles ( Fig. 26 ).

Female (Gandzhina)

HABITUS. See Fig. 23 C, G.

BODY LENGTH. 4.35.

COLOUR. As in male but abdomen slightly darker dorsally, and ventrally with darker X-shaped spot in genital area.

CARAPACE ( Fig. 23 I). 1.62 long, 1.29 wide.

ENDOGYNE ( Fig. 26 A–C). With large and wide conical median receptacles and small globular lateral receptacles; median receptacles with corrugated stem, their bases separated by less than the diameter of their heads, heads separated by 1.6 of their diameter; heads of both pairs densely covered with gland pores.

Variations

Carapace length in females varies from 1.50 to 1.75. Variation of coloration and structure of the endogyne in females from Tajikistan and Turkmenistan is shown in Figs 23 A–B, D–F, and 26D–O, respectively. The body and leg pattern, including the X-shaped spot in the female genital area, may be well-developed or indistinct.

Ecology

This species is found in different habitats from foothill steppes and shrubland to open Juniperus forest in the middle mountain belt. The spiders occur under stones ( Fig. 50 B), and in crevices in clay escarps ( Fig. 50 C) and rock outcrops ( Fig. 50 D) where they build small webs below or near the cavity entrance ( Fig. 50 E, a close-up view of such a web is also shown in Fig. 50 F).

Distribution

Tajikistan and Turkmenistan ( Fig. 48 ).
