Ultrastructures of aedeagus and spermatheca of Chaetocnema (Chaetocnema) scheffleri (Kutschera, 1864) (Chrysomelidae: Galerucinae: Alticini) by Scanning Electron Microscope
Abstract : The paper presents unknown ultrastructures of aedeagus and spermatheca of Chaetocnema scheffleri (Kutschera, 1864) which is one of the species of the nominate subgenus Chaetocnema (Chaetocnema) Stephens, 1831 are studied and figured under both stereo microscope and Scanning Electron Microscope from Turkey for the first time. The studied specimens were collected from Kayseri province in 2016 and 2018. Aedeagi and spermathecae so far were studied on the basis of only stereo microscopic studies within the genus Chaetocnema Stephens. Until now, there is only one ultrastructural study with SEM on male and female genitalia of Chaetocnema (Chaetocnema) Stephens, 1831 species, as Chaetocnema concinna (Marsham, 1802), therefore, the present study is the first for Chaetocnema scheffleri (Kutschera, 1864). In accordance with this, to reveal and to obtain new diagnostic characters with ultrastructural and detailed investigations of aedeagus and spermatheca of the species Chaetocnema scheffleri is basically aimed with this study. It is revealed new diagnostic characters for both the aedeagus and spermatheca by investigations on ultrastructural morphologies in SEM.
