Morphometric study and sexual dimorphism analyses in an Iranian population of Scorpio maurus (Arachnida: Scorpionidae)

Scorpio maurus (Scorpiones: Scorpionidae) which has a worldwide distribution, indicates levels of sexual dimorphism. Morphometry is used to determine the sexual dimorphism between the two sexes. In this study, 53 morphological characters of 15 specimens of each sex of Scorpio maurus were studied, however dimorphism was only observed in 21 morphological characters, including chelicerae and carapace length, pedipalp characters, width of the second segment of metasoma, telson and pectin length, number of left pectin teeth, and some of the leg's segments.
