Abstract
Sexual dimorphism is one of the most notable sources of phenotypic variation in animals. The expression of sexual traits varies widely for many species of insects. In this study, we analyzed the sexual size and shape dimorphism of pronotum in Turkish endemic species, Dorcadion micans J. Thomson, 1867 (Coleoptera: Cerambycidae). Our results have showed that there is statistically significant sexual size and shape dimorphism in pronotum. Males have a longer and sharper pronotum shape with smaller pronotum size than females. Multivariate regression results indicated that size has negligible influence on the differentiation in pronotum shape between sexes.
