The paper presents ultrastructures observed by SEM of aedeagus and spermatheca of Cryptocephalus sericeus (Linnaeus, 1758) that is a Sibero-European species (Coleoptera: Chrysomelidae: Cryptocephalinae) from Turkey for the first time. With the present study, the morphologies of male and female genitaliae of this species belonging to the nominative subgenus Cryptocephalus (s.str.) collected from Ankara, Çorum, Kastamonu, Kayseri, Kırklareli and Nevşehir provinces are examined using SEM (Transmission Electron Microscopy). To date, there has not been a study in Turkey in this context in which male genitalia (aedeagus) and female genitalia (spermatheca) morphologies of the Cryptocephalus sericeus (Linnaeus, 1758) have been studied together. The genus Cryptocephalus is represented by 73 species in Turkey. Detailed investigations of aedeagus and spermatheca are very important to obtain new diagnostic characters in the genus Cryptocephalus. For this reason, ultrastructural and detailed investigations of aedeagus and spermatheca of Cryptocephalus sericeus (Linnaeus, 1758) from Turkey were firstly studied with SEM and stereo microscope to obtain new diagnostic characters in the genus Cryptocephalus.The new diagnostic characters obtained by examining the ultrastructure of aedeagus and spermatheca belonging to the species will be used in the distinction of species that are especially similar to each other, by determining the differences and important characters among the species in the genus Cryptocephalus. Photos in SEM as well as photos in stereo microscope are also given in the text.
