Zaitunia annulipes - group

Remarks

This group unites moderately dark-coloured species. The clypeus, the eye tubercle and the carapace margins are noticeably darker than the general background colour. The abdomen is uniformly darkcoloured or with a weak, darker dorsal pattern. Legs I–IV are lighter than the body and provided with relatively narrow darker fasciae. The male palpal tibia is moderately short. The conical tegulum is much shorter than the cymbium. The embolus is a relatively long to very long apically twisted lamina. Keel of embolus absent. The vulva has two pairs of receptacles. Three species are included: Zaitunia annulipes ( Kulczyński, 1908) from Cyprus, Zaitunia kunti sp. nov. from Cyprus and Turkey, and Zaitunia minoica sp. nov. from Crete.
