Cephaloplatus

(after Gross 1976): Rather oval and moderate-sized Pentatominae, reddish-brown, yellowish-brown, or blackish-brown in colour. Head rather large, apically flattened or even concave. Juga laterally expanded, produced well in front of the anteclypeus, their anterior margins rounded or truncate, their lateral margins sometimes produced into a prominent lobe or spine in front of the eyes. Antennae slender. Pronotum rather flat, the anterior margin strongly concave, the lateral margin explanate and produced into a flattened angulate or lobate process which reaches forward to at least the posterior margin of the eye and lies just exteriorly of the true anterior angle. Behind this the anterolateral margins may be expanded laminately, frequently crenulate or serrate. Scutellum substantially triangular and somewhat larger than usual in Pentatominae. Hemelytra always wider than the abdomen in their basal half, generally narrowing apically. Laterotergites unarmed. Beneath the bucculae do not reach the base of the head, the prosternum is shallowly depressed, the mesosternum is a little convex and has a median longitudinal raised line or flattened ridge. The pygophore of the male has a characteristic posterior V-shaped or arcuate raised ridge below.
