Description
figure (1) Tergite without curved anterior transverse sulcus, Tarsus of the ultimate leg without spur, Coxopleural process long or of moderate length and with 6 or more spines and 1 or 2 side spines, Tergite with a median longitudinal suture, basal 5, 6 or more antennomeres glabrous. First pair of legs with 2 tarsal spurs, rarely with only 1, Each forcipular coxosternal tooth plate with 4 teeth, the lateral large and well separated, the medial 3 small and more or less fused. Forcipular trochanteroprefemoral process without teeth. Tergite 1 without longitudinal sutures, median suture of tergite 21 complete or almost so. Antennal segments with 18 antennomeres, with basal 10 to 12 antennomeres glabrous. Prefemoral process of ultimate legs mostly with 2 or 3 spines, the setae appearing gradually. Prefemoral process of ultimate leg mostly with more than 2 spines, Ultimate legs of male and female glabrous.

Distribution in Egypt
(Table 1) The distribution of this species is more widespread all over Egypt.
Description: figure (2) Some tergites anterior to tergites 20 and 21 marginate, Prefemora of ultimate legs with spines not on elongated processes but sometimes on a swollen base Mostly with sternite paramedian sutures although these may be weak and incomplete, Prefemora of ultimate legs with 5 to many spines ventrally, Tergite 21 with a median longitudinal suture, Head plate without anterior diverging paramedian sutures and basal plates. Forcipular coxosternum without ramifying sutures. Head plate with incomplete posterior lateral sutures, Head plate lacking a median suture. Antennal segments with 19 antennomeres, basal 5–10 antennomeres glabrous. Leg 1 with a single tarsal spur. Coxopleuron with a side spine and coxopleural process with 3–5(7), mostly 4 apical spines. Pretarsus (claw) of ultimate leg shorter than the second tarsus and not serrate ventrally, Ultimate leg prefemur with 7–10 ventral spines, typically in 3 rows of 3, Ultimate leg prefemur with 4 to 6 dorsomedial spines in two rows, Porose area extending to the posterior edge of coxopleuron. Prefemur, tibia, and often tarsus of the ultimate leg of male dorsally flattened with swollen edges.
Histochemical
Figures 4 and 5 (D) showed the venom apparatus of both collected species which consists of a pair of maxillipeds of equal size found inside a chitinous covering and the venom glands situated anteriorly in the prosoma on either side of the first segment of the body. The glandular epithelium is folded and made up of secretory epithelium that is surrounded by a striated muscle sheath. The secretory epithelium is made up of abundant cytoplasmic venom granules and high columnar venom-producing cells. The glandular canal is bordered with a chitinous interior layer and simple cuboidal epithelium and lacks muscles. (Fig. 4,5 (A,B) ).
The venom-producing cells are filled with granules with small nuclei situated at their bases. (Fig. 4,5 (A)).
The venom-producing cells reacted positively with the alcian-PAS reaction due to the presence of carbohydrate excretion (Fig. 4 (B),5 (C)). Also, reacted positively with bromophenol blue techniques due to the presence of protein inside the cells (Fig. 4(C),5(B)).
