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.

During the taxonomical investigations of Coleoptera (family: Meloidae) of the Arak County, in spring and summer 2010, 15 species of blister beetles belonging to the two subfamily (Nemognathinae and Meloinae), three tribes (Mylabrini, Lyttini and Nemognathini) and six genus (Hycleus, Mylabris, Alosimus, Calydus, Teratolytta and Nemognatha) were collected and identified. In this study the geographical distribution and identification key of the collected species of blister beetles were considered. This is the first time that Calydus ornaticollis species from Arak and Teratolytta flavipes species from Iran was reported. Morphological characters such as mesosternum, antennae, pronotum, and male reproductive organ were the main identification character that was used.
