Material examined

Crimea: four paratype females from Rhamnus daυurica Pall ( Rhamnaceae ); South Africa: Northern Cape Province: 10 females from Citrus sp., Augrabies (28 ° 379S, 20 ° 229E) near Kakamas and Zeekoeisteek near Blouputz (29 ° 499S, 21 ° 229E) , Northern Cape Province, 14 May 2003, T. G. Grout .

Diagnosis

Adults. This species is unique in having four pairs of genital and aggenital setae.

Female (n55). Dimensions (measurements of a paratype in parentheses): length of body, 246–268 (252); width (at level of c setae) 117–132 (130); legs: I 138–146 (148); II 94–108 (104); III 101–108 (104); IV 104–110 (120); setae: υi 9 (9); υe 9 (9); sci 25–28 (25); sce 13 (13); c 1 9 (9); c 2 16 (16); d 9 (9); e 13 (13); f 1 13–16 (14); f 2 22–28 (22); h 1 25 (22); h 2 28– 32 (25); ps 1 19–25 (16); ps 2 16–19 (16); ps 3 9 (9) .

Dorsum ( Figure 1 View Figures 1–6 ): all dorsal setae plumose. Prodorsum with four pairs of setae, with sci the longest ( Figure 2 View Figures 1–6 ). No eyes are visible. Opisthosoma with eight pairs of setae and three pairs of slitlike cupules ( ia, im and ip). Striae longitudinal on prodorsum, transverse medially and longitudinal to diagonal laterally on opisthosoma.

Venter ( Figure 3 View Figures 1–6 ): genital region with two pairs of eugenital setae in acetabulum and four pairs of genital and aggenital setae. Epimeral formula 3-1-3-3. Cupule ih lateral to setae ps 3. Anal opening caudally with three pairs of anal setae ( ps 1–3), with ps 1–2 being dorsal.

Gnathosoma ( Figure 4 View Figures 1–6 ): palp chaetotaxy (tarsus to trochanter): 5-2-2-0. According to André (1980, 1985) it is 6-2-2 with a solenidion on tibiotarsus. This solenidion is difficult to detect and was observed only once in a remounted specimen (H. M. Andre´, personal communication). A thorough examination of the tibiotarsus of paratype and local specimens showed only five setae and no sign of a solenidion. Tibiotarsus with seta pζ tridentate distally, d forked distally, l 0 plumose, and setae l 9 and ba simple. Cheliceral stylets (11) almost half the length of palp tibiotarsus (19).

Legs ( Figures 5, 6 View Figures 1–6 ): leg chaetotaxy as in André (1985). Solenidia on tarsi I–II very short, club-shaped. All leg setae plumose. Coxae I without coxal glands.
