Female (holotype and one additional specimen).

Dorsal shield reticulate ( Fig. 71 ); 390 [343] long and 197 [177] wide, with 18 pairs of setae, with five pairs of pores and 14 pairs of lyrifissures. Soft skin anterior to dorsal shield with two groups of three transverse, contiguous platelets. Setae j1 29 [29], j3 40 [31], j4 24 [18], j5 23 [21], j6 25 [23], J2 28 [25], J5 13 [10], z2 23 [23], z3 34 [30], z4 33 [25], z5 20 [18], Z4 57 [51], Z5 65 [62], s4 37 [29], s6 38 [34], S2 41 [39], S4 45 [34], S5 25 [25], r3 32 [26], R1 31 [25]. Dorsal setae smooth. Peritreme ( Fig. 75 ) extending forward to level between j1 and j3.

Venter ( Fig. 72 ). Sternal shield smooth, with two pairs of setae and one pair of lyrifissures; second pair of sternal lyrifissures (iv2) apparently on unsclerotised cuticle adjacent to posterior margin of sternal shield; st3 on unsclerotised cuticle and st4 on metasternal platelets; region anterior to first pair of sternal setae (st1) lightly striate. Distances between st1– st1 62 [62], st2–st2 71 [59], st3–st3 83 [70], st4–st4 81 [81]. Genital shield smooth, with lateral extensions; distance between st5–st5 73 [73]. Ventrianal shield subpentagonal, smooth; 119 [120] long, 109 [94] wide at ZV2 level and 100 [88] wide at level of anus; with four pairs of pre-anal setae and no pores. Seta JV5 65 [55]. Ventral setae smooth. Two pairs of metapodal plates.

Spermatheca ( Fig. 74 ). Calyx of spermatheca cup-shaped, 17 [16] long; atrium distinct, c-shaped.

Gnathosoma. Corniculi parallel to each other; basal width of corniculus 6, distance between bases of corniculi 5. Movable cheliceral digit 33 [27] long, with three teeth ( Fig. 73 ); fixed digit 31 [29] long, with three teeth; dorsal and lateral lyrifissures distinct.

Legs. Macrosetae sharp-tipped: Sge IV 33 [29], Sti IV 35 [24], St IV 64 [52] ( Fig. 76 ); macroseta of telotarsus IV 42 [36]; chaetotaxy of genu II 2, 2/0, 2/0, 1; genu III 1, 2/1, 2/0, 1.

Specimens examined. Holotype female from grapevine leaves, at New Valley governorate, September 1965 (coll. E.A. El-Badry); one adult female from same substrate, at Omar Makram village, Moderit el Tahrir, Beheira governorate, unknown collecting date (coll. E.A. El-Badry).

Previous records from Egypt. Asyut and Beheira governorates ( Zaher, 1986); New Valley governorate (El- Badry, 1968b; Zaher, 1986).

Remarks. This species was originally described from the holotype female collected in New Valley governorate, Egypt. The original description was reasonably detailed, with illustrations and setal measurements. According to the original description of the species and according to El-Badry (1970), the sternal shield of this species bears three pairs of setae, although in both publications the margins of the shield was shown in broken lines, suggesting they are not clearly defined. Zaher (1986) also reported the sternal shield has three pairs of setae.
