Filistata afghana Roewer, 1962: 12 , figs 6, 9 (♀, in part, misidentified).

Zaitunia afghana – Zonstein et al. 2013: 69 , figs 13, 21–27 (♀, misidentified).

Diagnosis

By structure of the vulva, Z. huberi sp. nov. resemble Z. beshkentica but differ from them by the shape of the median receptacles, which are shorter and round (vs longer and tube-shaped in Z. beshkentica , cf. Figs 29 I–K, 30C–E).

Etymology

The specific epithet is given after the prominent German arachnologist Bernhard Huber, who has transferred some misplaced Asian genera from Pholcidae to Filistatidae .

Material examined

Holotype

AFGHANISTAN: ♀, surroundings of Pol-e Khumri city, 35º57' N, 68º42' E, 700 m, 9 Nov. 1957, K. Lindberg ( SMF).

Paratype

AFGHANISTAN: 1 juv., collected and deposited together with holotype.

Description

Female

HABITUS. See Fig. 30 A–B.

COLOUR. Whole body and legs light brownish-yellow, abdomen without dorsal pattern, tarsi of palp and legs I–IV darkened, eye tubercle blackish-brown.

CARAPACE. 2.13 long, 1.77 wide.

EYES. AME 0.09, ALE 0.23, PLE 0.20, PME 0.20, AME–AME 0.11.

ENDOGYNE ( Fig. 30 C–E). Both pairs of receptacles globular, median receptacles separated from each other by the same distance as lateral and median receptacles; median receptacles larger, separated by less than one diameter.

Male

Unknown.

Note

See comments in the redescription of the holotype of Z. afghana . Both of these species are very similar in somatic characters, which probably misled Roewer (1962). Nevertheless, they differ so drastically in the structure of the endogyne (cf. Figs 14 G–K, 30C–E) that they are assigned here to different species groups.

Distribution

Known only from the type locality ( Fig. 49 ).
