Aedeagus of Pyrrhalta maculicollis in the lateral view 1 relative size of the aedeagus compared to body size 2 the aedeagus and a part of the ejaculatory duct, muscles completely macerated. Two arrows point to the membranous areas of the median lobe 3 a micro CT scanned and segmented aedeagus and a part of the ejaculatory duct. The green structure represents the part of the ejaculatory duct with well–developed circular muscles, the yellow one represents the median lobe, and the red ones represent spines on the internal sac 4 the internal sac at rest with a part of the ejaculatory duct (ed) 5 schemes of the aedeagus at rest (left) and with partly evaginated internal sac during copulation (right). Abbreviations: aed, aedeagus; ed, ejaculatory duct; is, internal sac; ml, median lobe.
