Galapagoliarus alastor
Planthoppers
The form of the aedeagal complex in Galapagoliarus alastor is atypical. The endosoma is expanded and has an additional dorsal subapical process, pointing medially. The apical process of the endosoma is greatly angled inwards, compared to the usual cephalad angle in the rest of the genus (Hendrix & Bartlett, 2025).
