Brachylophora, a new brachypterous genus of Rhopalophorini (Coleoptera, Cerambycidae). Brachylophora auricollis (Bruch, 1918) comb. nov. = Pasiphyle auricollis Bruch, 1918, originally described from Argentina (Salta), is redescribed and illustrated. Although with reduced elytra, the genus is transferred from Rhinotragini to Rhopalophorini based on the following characters: eyes well separated in both sexes, frons between eyes depressed and lacking frontal suture; pro-, meso-, and metasternum planar; mesothorax parallel-sided, not at all declivous before mesosternal process; metasternum large, together with mesosternum twice length of prosternum, metepisternum very wide, entire suture separating it from metasternum clearly visible when viewed from below; female ovipositor shortened with short cylindrical styles; and, more generally, structural features of hind legs, and surface ornamentation. Habitus similar to Coremia group. Bolivian specimens were netted as they visited flowers of Croton sp. (Euphorbiaceae).
