Fulcidax Voet, 1806: 33; Type species: Fulcidax azureus Voet, 1806 = Clytra monstrosa Fabricius, 1798, by monotypy; Jacoby, 1881: 90 (Central American species); Monrós, 1952: 641 (overview of genus); Blackwelder, 1946: 650 (catalog); Seeno and Wilcox, 1982: 43 (catalog).

Poropleura Lacordaire, 1848: 863; Type species: Clytra monstrosa Fabricius, 1798, by subsequent designation of Navajas, 1946: 245.

Diagnosis. Length 6.50-7.20 mm, width 4.60-5.00 mm. General body shape subquadrate, metallic coloration. Antenna serrate beyond 3 rd antennomere, 2 nd and 3 rd antennomeres slightly widened, but not dilated distally. Head with the vertex longitudinally impressed. Pronotum with median elevation, surface tuberculate. Pronotal base opposite mesoscutellum (posterior pronotal lobe) with acute notch. Prosternum acutely narrowing posteriorly, prosternal process 2/3 size of entire prosternum. Anterior margin of metasternum concave. Mesoscutellum trapezoidal. Metascutellum not exposed. Sutural serration of elytra well developed beyond middle of suture towards the apex. Elytral tubercules pronounced. First ventrite with lateral tubercles. Tibiae slightly curved, flattened, with sharp dorsal edge. Fore- and midtibial apices with spine. Tarsal claw simple.

Distribution. Central and South America (Monrós 1952).

Remarks. Fulcidax can be distinguished from all other chlamisine genera by the longitudinally impressed vertex of the head, simple tarsal claws, large body size, and usually bright metallic coloration.

Currently, 7 species are included in the genus (Monrós 1952).
