The following key incorporates the primary characters needed to separate the genera involved in this study:

1. Eyes very finely granulated ( Figs.1‑3 , 10‑12 ) ....................................2

— Eyes slightly to distinctly coarsely granulated ( Figs.4‑6, 7‑9 , 13‑15 ).3

2(1). Elytra distinctly carinate dorsally ( Fig.10 )....................... Scythropopsis

— Elytra without carina distant from suture ( Fig.1 )................................. ............................... Acanthoderes (Acanthoderes) and A. (Pardalisia)

3(1). Pronotum ( Figs. 13‑14 ) with distinct central depression, from near base to near apex or only in anterior region, margined by lateral elevation (carinate or not)........................................... Symperasmus

— Pronotum ( Figs. 4‑5, 7‑8 ) not distinctly depressed centrally, nor with lateral tubercles forming carina................................... Aegomorphus
