Sexual Dimorphism and Ultrastructure of Coraliomela brunnea (Thunberg, 1821) (Coleoptera: Chrysomelidae)
摘要
This study analyzed the morphological characteristics of C. brunnea adults that allow for sexual differentiation. Sensilla trichodea, spatulate setae and lanceolate setae were found on the antennae, tarsi and tibiae apex, respectively, with no difference between sexes. Females of C. brunnea have a longer and wider body, as well as a longer fifth urosternite compared to males. The shape of the fifth urosternite allows for sex differentiation in C. brunnea adults.
