Zaitunia sp. – Zyuzin & Tarabaev 1994: 399.
Diagnosis
By structure of the bulb, Z. spinimana sp. nov. resembles Z. martynovae but differs from the latter by its shorter and narrower corkscrew-shaped embolus (cf. Figs 24 A–D, 43F, 27C–E, 44A). Additionally, it differs from Z. martynovae and all other congeners by having a femur, tibia and metatarsus I with unusually numerous, long spines (Figs 27 A). By structure of the vulva, Z. spinimana sp. nov. is similar to Z. inderensis; they differ by the receptacles, which are subequal in size (Fig. 27 H–I).
Etymology
The specific epithet is derived from the Latin spina- (thorn, spine) and -manus (hand, appendage); the proposed name refers to the spiny legs of the male.
Material examined
Holotype
TURKMENISTAN: ♂, Ustyurt Plateau (southern part), Kaplankyr Nature Reserve, 29 Apr. 1986, L. Mitroshina (TAU).
Paratype
KAZAKHSTAN: 1 ♀, Mangystau Province, 40 km S of Aktau, 7 Jun. 2013, G. Abdurrakhmanov (ZMMU).
Note
The holotype male and the only collected paratype female are very similar in possessing a very similar shape of the carapace (flattened more than usual) and a similar conformation of the eye group. Although the distance between the localities listed above is about 500 km, these slightly hilly and extremely uniform desert landscapes have no significant natural barriers. We prefer currently to treat these specimens as the same species (with no serious objectives against this assumption) rather than consider them representatives of two very close but distinct species.
