Zaitunia inderensis Ponomarev, 2005: 43 , fig. 1a–b (♀).

Zaitunia inderensis – Fomichev & Marusik 2013: 85, figs 10–11, 15 (♀).

Diagnosis

By the structure of the vulva, females of Z. inderensis resemble Z. spinimana sp. nov., but differ from it and all other congeners by the enlarged lateral receptacles which are considerably larger and more robust than the median pair ( Fig. 22 E).

Material examined

Holotype

KAZAKHSTAN: ♀, Atyrau Province, Inder plateau , karst sinkhole 20 km E of Inderborskiy (=Inderbor) town, 48º33' N, 52º01' E, 29 Sept. 1986, A.V. Ponomarev ( ZMMU).

Paratypes (5 ♀♀)

KAZAKHSTAN: 2 ♀♀, same data as holotype ; 3 ♀♀, same data, but 25 May 1987 ( ZMMU) .

Description

Female (holotype)

HABITUS. See Fig. 22 A.

BODY LENGTH. 3.66.

COLOUR. Whole spider pale yellowish-grey; eye tubercle brownish; abdomen lacking dorsal pattern.

CARAPACE ( Fig. 42 C). 1.34 long, 1.02 wide.

EYES. AME 0.07, ALE 0.13, PLE 0.10, PME 0.09, AME–AME 0.04.

ENDOGYNE ( Fig. 22 B–C, E). Median and lateral receptacles closely spaced and arranged almost in one longitudinal line (median receptacles partly hide lateral ones). Median receptacles very short; lateral receptacles diverging, clublike, with corrugated stems, head of receptacles separated by about 2.5 of their diameter; median receptacles separated by less than 1.5 diameters.

Unknown.

Variation

Carapace length in female paratypes varies from 1.19 to 1.40; no distinction in the colouration is evident.

Ecology

According to label data and the original description ( Ponomarev 2005), the species was found in a low, semi-desert karst plateau.

Distribution

Known only from the type locality ( Fig. 48 ).
