Somatic characters and female copulatory organ of paratype of
Zaitunia afghana
. 21–22, 24 body, dorsal, ventral and lateral, respectively; 23 prosoma, dorsal; 25 metatarsus IV showing calamistrum; 26–27 copulatory organ, 26 ventral and 27 dorso-anterior.
Diagnosis.
The species differs from congeners by the following characters: from
Z. schmitzi
—by pale-colored body and legs, and better developed eye tubercle (
cf
. Zonstein 2009: figs 3–5); from
Z. maracandica
(Charitonov, 1946)
and
Z. martynovae
(Andreeva & Tyshchenko, 1969)
—by absence of darker dorsal abdominal pattern and the different-shaped ocular region (
cf
. Charitonov 1946: fig. 3; Andreeva 1976: figs 13–14); from
Z. monticola
(Spassky, 1941)
—by having less slender and much shorter anterior legs (
cf.
Spassky 1941); from the similarly colored
Z. beshkentica
(Andreeva & Tyshchenko, 1969)
—by the shape and position of the spinnerets group (
cf
. Andreeva 1976: fig. 11); from
Z. alexandri

with described and figured female copulative organs—by the different configuration of the receptacles (
cf
. Brignoli 1982: figs 14–16; Fomichev & Marusik 2013: figs 12–15).
Description. Female
(
paratype
): Total length 5.35. Color in alcohol: whole body and legs light brownishyellow, abdomen without dorsal pattern, tarsi of palp and legs I–IV darkened, eye tubercle blackish-brown. Carapace (
Figs 21, 22, 24
): 2.13 long, 1.77 wide. Eye diameters: AME 0.09, ALE 0.23, PLE 0.20, PME 0.20. Interdistance AME–AME: 0.11. Measurements of legs and palp as shown in
Tab. 2
. Calamistrum placed on small ridge, strongly bent setae arranged in one row (
Fig. 25
).
Genital area of endogyna as in
Figs 13
,
26–27
; 2 genital plates covered with fine wrinkles (
Figs 13
,
26
), hairs near epigastric fold long, equal in length to the distance between the lateral margins of the main receptacles; two pairs of receptacles, all receptacles round and separated from each other by the diameter of the accessorial (lateral) receptacles.

: unknown.
Note.
A short steeply inclined clypeus, the loss of the thoracic fovea and the presence of short spatulate setae on tarsi I–IV are characteristic for
Zaitunia
and indicate that the given species belongs in this genus and not to
Filistata
, as previously assigned.
Distribution.
Сentral and northern parts of
Afghanistan
. We are not sure if all records of immature conspecific filistatids listed by Roewer (1962) refer to this species.
