description: Key to species of Aethodelphax (males)
1. Segment 10 in lateral view with pair of short ventral processes (or large teeth) near midpoint in addition to distal paired processes (Figs. 3 H, 7G, 8H)............................................................................... 2
1’ Segment 10 in lateral view lacking a pair of ventral processes near midline (distal paired processes present)............. 4
2. Aedeagus straight or slightly sinuate in lateral view with a lateral flange on one or both sides (Figs. 3 F–H, 8F–H); outer angle of parameres acute or acuminate; segment 10 with midventral processes ventrally directed........................... 3
2’ Aedeagus curved ventrad in lateral view, large flange lacking (Figs. 7 F–G); outer angle of parameres rounded; segment 10 with midventral processes lateroventrally directed; MS............................ paraparvulus (Beamer), comb. nov.
3. Aedeagus with subapical, dorsal tooth (Figs. 8 F–H), lateral expansion of aedeagus without large acuminate tooth; apices of outer angles of parameres acute; FL, GA, LA...................................... sagittatus (Beamer), comb. nov.
3’ Aedeagus without subapical, dorsal tooth (Figs. 3 F–H), with large, acuminate flange on left side; apices of outer angles or parameres acuminate; FL......................................................... alatus (Beamer), comb. nov.
4. Aedeagus strongly curved ventrad (Figs. 2 F–G); genital diaphragm bearing pair of subdorsal pegs, one on either side of aedeagus in repose; diaphragm armature not dorsally projecting; FL, LA, MS, TX.......... aetocephalus (Beamer), comb. nov.
4’ Aedeagus not strongly curved ventrad (aedeagus may be ventrally concave); genital diaphragm lacking subdorsal pegs, diaphragm armature dorsally projecting...................................................................... 5
5. Segment 10 in lateral view robust with small ventral excavation at base of distal paired processes (Figs. 4 G, 5G).......... 6
5’ Segment 10 in lateral view dorsoventrally flattened, with broadly rounded excavation at base of distal paired processes (Figs. 1 H, 6H)............................................................................................. 7
6. Aedeagus broadly flattened laterally bearing symmetrical teeth (Figs. 4 F–G); genital diaphragm armature weakly projecting dorsally; AZ, Mexico .......................................................... caninus (Beamer), comb. nov.
