Zaitunia beshkentica
species group
Remarks
This group includes pale-coloured species. The clypeus, post-ocular area, dorsal abdominal pattern and sometimes lateral margins of the carapace are slightly darker than the pale background colour. Legs I–IV, mostly lacking darker fasciae, are concolorous with the prosoma. The conical tegulum is much shorter than the cymbium. The relatively long embolus is provided with a well-developed raised keel. The vulva has two pairs of receptacles. Four species are included:
Z. beshkentica
(
Andreeva & Tyshchenko, 1969
)
from
Tajikistan
,
Turkmenistan
and
Uzbekistan
,
Z. psammodroma
sp. nov.
from
Turkmenistan
,
Z. wunderlichi
sp. nov.
from
Kyrgyzstan
, and (tentatively, because the male is unknown)
Z. huberi
sp. nov.
from
Afghanistan
.
