Diagnosis

By the structure of the bulb, Z. wunderlichi sp. nov. is similar to Z. beshkentica , but differs by the shape of the raised embolic keel, which terminates more gently (cf. Figs 28 G–I, 32D–F), whereas females differ by the structure of the vulva, which is more similar to those of Z. maracandica and Z. ferghanensis sp. nov.; they differ from both these species by the shorter median receptacles (cf. Figs 33 A–B, D, 35E–J, 38E–I).

Etymology

This species is named after the famous German arachnologist, our friend and colleague Jörg Wunderlich.

Material examined

Holotype

KYRGYZSTAN: ♂, Ferghana Mts , Baubashata Range, Yarodar, 2.5 km E of Arslanbob, 41°20'12" N, 72°58'23" E, 1450 m, 12 Aug. 1981, S. Zonstein ( TAU).

Paratypes (2 ♂♂, 1♀)

KYRGYZSTAN: 2 ♂♂, same data as holotype ( TAU, ZMMU) ; 1♀, Chatkal Mts, Arkit, 41º48' N, 71º57' E, 1300 m, 2 May 1983, S. Zonstein (ZMMU).

Note

Although males and the only collected female listed above were found in two separate areas distant from each other by about 100 km, they are very similar in having the same type of body and legs colouration, as well as in possessing a very similar carapace setation and a similar conformation of the eye group. Additionally, they all occurred in almost identical humid biotopes. Thus, we have no doubt that in both these situations, we are dealing with representatives of the same species.

Description

Male (holotype)

HABITUS. See Fig. 31 E.

BODY LENGTH. 2.78.

COLOUR. Whole spider pale greyish-yellow; eye tubercle dark brown; Y-shaped median spot occupying cephalic portion and extending to clypeus, and margins of carapace light brown; weak and diffuse dorsal abdominal pattern consisting of lancet-shape median spot anteriorly and a few transverse fasciae posteriorly pale brown.

CARAPACE ( Fig. 42 F). 1.18 long, 1.00 wide.

EYES. AME 0.06, ALE 0.10, PLE 0.10, PME 0.10, AME–AME 0.06.

PALP ( Figs 32 C–G, 44D). Femur slightly longer than tibia (in prolateral view); tibia 1.5 times wider that femur; cymbium as long as bulb; keel of embolic neck with straight margin (not curved in terminal part); tip of embolus bent downward.

LEG MEASUREMENTS. ♂(♀)

	Femur	Patella	Tibia	Metatarsus	Tarsus	Total
Palp	0.76 (0.84)	0.24 (0.35)	0.76 (0.57)	―	0.23 (0.62)	1.99 (2.38)
I	1.61 (1.69)	0.51 (0.56)	1.60 (1.63)	1.47 (1.44)	1.08 (1.14)	6.27 (6.46)

III	1.19 (1.15)	0.43 (0.52)	0.97 (0.91)	1.13 (0.86)	0.77 (0.63)	4.49 (4.07)
IV	1.68 (1.55)	0.56 (0.56)	1.48 (1.24)	1.61 (1.25)	1.01 (0.80)	6.34 (5.40)

Female

HABITUS. See Fig. 31 A.

BODY LENGTH. 4.11.

COLOUR. As in male, except without darkened carapace margins.

CARAPACE. 1.59 long, 1.27 wide.

EYES. AME 0.08, ALE 0.15, PLE 0.12, PME 0.10, AME–AME 0.05.

ENDOGYNE ( Fig. 33 A–B, D). Both pairs of receptacles long (especially lateral pair), cylindrical with somewhat dilated heads; lateral and median receptacles separated by about one diameter; lateral receptacles longer than median; median receptacles separated by 3 diameters; pores cover the entire receptacle.

Variation

Length of the carapace in males varies from 1.15 to 1.23, the body and leg colouration does not vary significantly.

Ecology

The species inhabits humid habitats including walnut forest of Juglans regia L. in the middle mountain belt, where it certainly prefers more open slopes, occurring under stones in low forest and shrubs.

Distribution

Southern Kyrgyzstan (Western Tian-Shan Mts) ( Fig. 49 ).
