title: On the taxonomic structure and variability of Macropsidius involutus Dlabola, 1963 (Homoptera: Cicadellidae: Macropsinae)—morphology and calling signal pattern
abstract: Variability of genitalia shape and male calling signal pattern in Macropsidius involutus from 10 localities in South-eastern Europe (the Crimea, the Lower Volga Region), Kazakhstan, and Kyrgyzstan was investigated. Variability of pygofer processes, penis shape, and signal pattern clearly has a geographic component, but none of these traits clearly supports subdividing this species into different subspecies unequivocally. M. involutus was found at altitudes from 0 up to ca. 2000 m a. s. l. in ste
