Diagnosis . Length 3.45-4.72 mm , width 2.18-3.22 mm . General body shape cylindrical. Body usually yellowish. Frons glabrous, canthus of eye as yellow as rest of frons. Pronotum and elytra glabrous. Head not completely retracted into prothorax; mandibles enlarged in males, normal in females ( Figs. 4 K, L ). Antenna serrate beyond 3 rd antennomere, 2 nd antennomere slightly widened, globose, 5 th antennomere as large as 6 th . Pronotum medially elevated, with small protuberances. Pronotal base opposite mesoscutellum (posterior pronotal lobe) with well differentiated notch. Prosternum strongly and abruptly constricted beyond anterior margin; prosternal process more than ¾ as long as prosternum. Anterior margin of metasternum concave. Mesoscutellum short, transverse. Metascutellum concealed by elytra. Sutural serration of elytra complete. Elytral tubercules poorly developed, their microsculpture not different from rest of body surface. Tibiae slightly curved, more or less cylindrical, with sharp dorsal edge and one more less developed ventral ridge. Fore- and midtibial apices without spine. Tarsal claw bifid or appendiculate. Distribution . North, Central, and South America ( Karren 1972 ). Remarks . Pseudochlamys can be distinguished from other chlamisines by the following characters: head not completely retracted into prothorax; mandibles enlarged in males, normal in females; fore- and midtibial apices without spine; prosternum strongly and abruptly constricted beyond anterior margin; and prosternal process more than ¾ as long as prosternum.
