Female (one specimen).

Dorsal shield strongly reticulate; 415 long and 207 wide, with 17 pairs of setae. Setae j1 25, j3 29, j4 14, j5 15, j6 17, J2 18, J5 14, z2 23, z4 20, z5 13, Z1 23, Z4 37, Z5 77, s4 31, S2 33, S4 34, S5 41, r3 31, R1 28. Dorsal setae smooth, except S4, S5, Z4 and Z5, faintly serrate. Peritreme extending to level of j3.

Venter. Sternal shield faintly reticulate, with three pairs of setae and two pairs of lyrifissures. Distances between st1–st1 57, st2–st2 68, st3–st3 77, st4–st4 77. Genital shield reticulate; distance between st5–st5 74. Ventrianal shield subpentagonal, strongly reticulate, 145 long, 120 wide at ZV2 level and 95 wide at level of anus; with three pairs of pre-anal setae and a pair of pre-anal pores. Seta JV5 62. Ventral setae smooth, except JV5, faintly serrate. Two pairs of metapodal plates.

Spermatheca. Calyx of spermatheca cup-shaped, 10 long.

Gnathosoma. Corniculi parallel to each other; basal width of corniculus 6, distance between bases of corniculi 6. Movable cheliceral digit 34 long, with one tooth; fixed digit 33 long, with 5 or 6 teeth.

Legs. Macroseta sharp-tipped: St IV 70; chaetotaxy of genu II 2, 2/0, 2/0, 1; genu III 1, 2/0, 2/1, 1.

Specimens examined. One female from soil under A. donax plant, at Senuris, Fayoum governorate, April 2001 (coll. R.I.A. Abo-Shnaf).

Remarks. This is the first report of this species from Egypt. It was originally described from the holotype female and nine paratype females collected in Kazakhstan. The original description was brief, but with illustrations and setal measurements; complementary descriptions were listed by Demite et al. (2014). Measurements of the single specimen collected are agree generally well with those of the original description of this species and with the corresponding ranges given by Ferragut et al. (2010). The peritreme of the specimens collected is slightly shorter than shown by Livshitz & Kuznetsov (1972) and Papadoulis et al. (2009), reaching only level of j3.
