Zaitunia spinimana - group

Remarks

This group includes relatively pale-coloured species. Only the clypeus, post-ocular area and dorsal abdominal pattern are slightly darker than the pale background colour. Legs I–IV mostly lacking darker fasciae and are concolorous with the prosoma. The conical tegulum is much shorter than the cymbium. The embolus is relatively long to very long. The endogyne with two pairs of receptacles. Three species are included: Z. martynovae ( Andreeva & Tyshchenko, 1969) from Tajikistan, Z. spinimana sp. nov. from Turkmenistan and Kazakhstan, and (tentatively, because of the unknown male) Zaitunia inderensis Ponomarev, 2005 from western Kazakhstan.
