All dorsal setae smooth, except Z5, which is slightly serrate .

Peritreme — Extending to level between setae z2 and z4.

Venter — Sternal shield with three pairs of setae (St1, St2 and St3); distances between St1-St1 67 (65 – 68), St2-St2 74 (70 – 75), St3-St3 89 (85 – 90), St1- St3 67 (65 – 68), St4-St4 112 (109 – 115). Distance between genital setae St5-St5 83 (80 – 88). Ventrianal shield 95 (93 – 103) long, 65 (63 – 68) wide at level of ZV2 and 67 (63 – 75) wide at level of anus, with three pairs of setae and a pair of large pores posteromesad to JV2; JV5 45 (43 – 53).

Chelicera — Fixed digit 25 long, with two prominent and apical teeth, and four minute teeth clustered midway along digit; movable digit 23 long, unidentate.

Spermatheca — Calyx elongate, narrow flaring towards vesicle, 37 long.

Legs — SgeII 27, SgeIII 39 (38 – 40), StiIII 31 (30 – 32), SgeIV 62, StiIV 47 (45 – 50), StIV 81 (78 – 85).

Remarks — Measurements of the specimens collected are close to those of the original description ( Athias-Henriot, 1958a). However, setae j3, J2, z2, z4, Z5 and S2 are about 20 – 30 % longer than those of specimens from Cape Verde ( Ueckermann, 1992) and Ghana ( Moraes et al., 2001). The number of teeth on fixed digit of Syrian specimens is close to this illustrated by Ueckermann (1992). However it is different from specimens examined by Cobanoglu (1989) (2-3 teeth), and by Ferragut and Escudero (1997) (3-4 teeth).
