Ticks are scattered all over the world as aquatic and terrestrial groups. Livestock ticks are obligate parasites that target small and large livestock. In this study, 5 stations in the Kojur region were selected and livestock were sampled. The tick samples collected in Eppendorf bottles containing 70% ethanol and 5% glycerin were transferred to the laboratory of Arak University. They were identified with the help of valid identification keys of their genus and species. In this research, 173 livestock including 95 cattle and 78 sheep were studied, of which 139 were infected with ticks. A total of 572 ticks (420 ticks belonging to the hard tick family and 152 ticks belonging to the soft tick family) were collected. From the Ixodidae family, six species belonging to the three genera Hyalomma, Haemaphysalis, and Rhipicephalus, including two species Hy. anatolicum and Hy. asiaticum, two species of Ha. Punctate and Ha. sulcata, and two species R. Sanguineus and R. Turanicus were identified. In the family Argasidae 2 genera and 3 species were identified, which genera include Argas and Ornithodoros. In this family, Argas species were completely distinguished from Ornitodoros species. From the Argas genus, A. persicus and A. reflexus species and from Ornithodoros genus, O. lahorensis species have been isolated and identified.

In animals, Sexual dimorphism can be based on morphological characteristics or measurable characteristics. In scorpion, except a few species that have two sexual forms, there is no significant difference between males and females. In this study, 12 measurable characteristics of male and female Hottentotta saulcyi, from the Rudbar area located on the border of Lorestan, Isfahan and Chaharmahal and Bakhtiari provinces, were measured and analyzed by SPSS 16 software. Independent Sample T-test showed a significant difference between the three traits, the distance between the two shoulder lines, shoulder length, and the number of shoulder teeth between males and females. The result showed that in male, the length of the shoulder is significantly larger and also the number of shoulder teeth more than female, but the distance between the two shoulder strains in the material is larger than the male, and therefore, these traits can be in the diagnosis of both males and females.
