Dorcadion micans J. Thomson, 1867 (Coleoptera: Cerambycidae) Pronotumunda Geometrik Morfometri Kullanarak Eşeysel Dimorfizm

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 showed that there are a statistically significant sexual size and shape dimorphism in pronotum. Males have a smaller pronotum size than females, and the pronotum shape of males is longer and sharper than female. Multivariate regression results indicated that size has a negligible influence on the differentiation in pronotum shape between sexes.
