Detailed Morphological Characterization of Male and Female Genital Structures in Radymna fischeri Faldermann, 1837

Abstract

The paper presents unknown ultrastructure observed by scanning electron microscope (SEM) and stereo microscope of aedeagus and spermatheca morphologies of Radymna fischeri Faldermann, 1837 (Coleoptera: Chrysomelidae: Galerucinae) from Türkiye. This species, which belongs to one of the genera that is very important in biological control, where it was collected in Çankırı on 2023. The genus Radymna Reitter, 1913 includes 9 species in the Palaeartic Region, while it is represented by 5 species in Türkiye. As known, aedeagus and spermatheca morphologies are taxonomically important structures. Before the present study, however, there are no work on these structures of Radymna fischeri Faldermann, 1837. For this reason, ultrastructural and detailed investigations of aedeagus morphology of Radymna fischeri Faldermann, 1837 from Türkiye were firstly studied with SEM to contain male and female genital descriptions of Radymna fischeri Faldermann, 1837. Photos in SEM and stereo microscope are also given in the text.
