Type species. Platycerus keeni Casey, 1895 , by original designation.

Subgeneric description. Differing from the other subgenera in the following characters: Head: Anterior margin distinctly emarginate (Fig. 19), rarely less emarginate. Genae usually produced laterally past eyes (greatest width of head is across genae). Wings: Males with functional wings or wings absent. Abdomen: Male genitalia ( Figs. 13 B, 14C) with internal sac (flagellum) short, not reaching beyond parameres in repose, flagellum with strongly sclerotized, median, hooked process and weakly sclerotized, lateral, wing-like processes. Parameres simple, not emarginate in lateral view ( Fig. 1 A).
