The holoventral plate had 23 setae, including 5 pairs in sternogenital region, 5 pairs in preanal region and 3 anal setae. The peritreme extended anteriorly behind coxa 2 from an oval pit situated ventro-laterally between coxae 3 and 4. Gnathosoma consisted of long basis capituli carrying median hypostome and 2 lateral pedipalps. Hypostome had median labium terminated with 2 lobulated plates, cheliceral digits forming pincers-like claw and 2 pointed corniculi. Each pedipalp terminated with tarsus that carried 9 sensillae forming the palpal organ. Small conical sensillae assumed to be chemoreceptors while long broad ones were probably mechanoreceptors. Pulvillis 1 had smooth surface and terminated with 2 small claws and integumental folds. Pulvilli 2-4 had smooth dorsal surface, ventral longitudinal ridges and 2 lateral plates, each with minute processes.]]>Aamir, M.M.I., O.A. Nassar, A.A.E. Fishawi and R.M.
