Surveying on the biologic behaviors of Hemiscorpius lepturus Peters 1861, scorpion in laboratory (Khuzestan, Iran) (Scorpions: Hemiscorpiidae).

This descriptive research was conducted so as to find and distinguish the sex of H. lepturus based on 107 dead specimens in the 70% ethyl alcohol and exact decision on their species using a criterion considering all morphological parameters and by the use of stereo microscope. Their biologic behaviors, 50 H. lepturus specimens which were fed and kept alive in capped bottles were studies while their way of shedding and number of newly-born young were also investigated under laboratory conditions in the process. The research revealed that in 107 H. lepturus specimens, 27 specimens (23%) were male and 80 ones (77%) were female. The results gained from 50 scorpions kept in the laboratory showed that only 10 cases (20%) had shed. Duration of emergence varies in each young from 10-20 min and delivery lasts approximately for 4-6 h. The average number of the young born was 24.3 in each delivery. It was concluded that the time of delivery and shedding in H lepturus is definitely fixed during the year and the number ofpectine denticles and length of the tail can be used to differentiate male and female H. lepturus.
