It can be observed under stones or beneath rotten vegetation in habitats with rather deep soils (forested valleys, palm grooves along wadis, bushlands). It was reported also among droppings of goats ( Schätti & Desvoignes 1999 ). We have collected it from 20 m of altitude at Wadi Qishn to 380 m south of Rokeb, but the species was collected at Diksam ( 695 m ) by H. Rösler (Rösler & Wranik, 2004) and Schätti & Desvoignes (1999) cited it from Homhil at 700 m . Original data. Fig. 26. Go'o area, Qeysoh, Wadi Ayhaft, Hadiboh plain, Di Lishah area, Rokeb area.
