FIGURE 1. Measurements taken and views used to take them, exemplified with a male of A. aegrotus. Scales: 500 µm. A Head, dorsal view: rostrum width at apex, rostrum width at base, distance between eyes above, head width. B Head, lateral view: rostrum length. C Head, ventral view: distance between eyes below. D Eye, frontal view: eye height and eye length. E Prothorax, dorsal view: prothorax length, prothorax width at base, scutellum length, scutellum width (in case scutellum at a different angle, an additional view with a detail of the scutellum was used). F Prosternum, ventral view: length of prosternum, coxal width. G Elytra, dorsal view: width of one elytrum. H Elytra, lateral view: length of elytra. I Proleg, lateral view: length of profemur, width of profemur, length of protibial, width of protibial.

K Male genitalia, dorsal view: width of aedeagus at base. L Male genitalia, lateral view: Length of aedeagus following the ventral curvature, length of ventral sclerotization beyond the insertion of apodemes, height of aedeagus, length of an apodeme following its curvature.
