Zaitunia zonsteini Fomichev & Marusik, 2013: 85 , figs 1–9, 12–14 (♀).

Diagnosis

Females of Z. zonsteini , with their very short and small receptacles, resemble those of Z. minuta sp. nov., but differ by having smaller eyes, broader calamistral setae, a larger cribellum and more globular receptacles (both pairs) (cf. Figs 39 D–H, 40, 41D–M).
