Phyllomacromia maesi (Schouteden, 1917)
Blackwater Cruiser

Type locality: Inongo, DRC


Male is similar to many other species by (a) larger size, Hw 30-42 mm; (b) thorax with 3 pale stripes on each side; (c) dorsum of S10 with peak bearing 1 cone; (d) cerci and epiproct are both dark. However, differs by (1) border of hamule strongly sinuous; (2) S10 with small tooth on posterior side of base of peak; (4) cerci widened before tip, but tip itself pointed, cerci thus appear truncate (dorsal view).
