Key to the Genera of the Agaveocoris Complex of Eccritotarsini

1. Male genital capsule with a stout, apically rounded tubercle on left side, tubercle rarely more spinelike, but never visible in dorsal aspect; body oval to elongate oval................................................................... 2

– Male genital capsule with an elongate apically pointed spine on left side, often visible in dorsal aspect; body elongate oval. 4

2. Uniformly dull black, often flattened, species (Figs. 50, 53, 56); right paramere broadly rounded or spatulate apically (Figs. 106, 108, 110, 112)................................................................. Nigrotomocoris, n. gen.

– Multicolored species, head and pronotum often yellow or orange, contrasting with a darker hemelytron, often with a bluish sheen; right paramere never spatulate apically................................................................3

3. Mostly elongate-oval species; eyes substylate (Figs. 11–42), inner margin of eye level with outer anterior margin of pronotum; calli prominent (Figs. 2–4), strongly raised with a depression between; right paramere with a distinct upturned hook at apex (Figs. 72, 74, 76, 79).................................................................... Agaveocoris, n. gen.

– Mostly short, round species; eyes less produced, level of inner margin of each eye well inside outer anterior margin of prono- tum; calli flat, not strongly raised; apex of right paramere acute, without an upturned process....... Halticotoma Townsend

4. Hemelytra (1s. 43–48) dark brown to fuscous, often with a bluish sheen; basal half of antennal segment II thicker than apical half; left paramere U- or C-shaped (Figs. 100, 102)....................................... Laterospinocoris, n. gen.
