Assycuera gen. n. (type species: Anyclocera macroteta Bates, 1880) is proposed to accomodate four species formerly placed in Ancylocera Audinet-Serville, 1834: Assycuera waterhousei (White, 1855) comb, n., Assycuera macrotela (Bates, 1880) comb, n., Assycuera rubella (Bates, 1892), comb. n. and Assycuera scabricollis (Chemsak, 1963) comb. n. The characters used to assemble these species into the new genus were mainly the gradually clavate femora and the antennae of the male with the 11th segment elongate, filiform, the scape not enlarged at base and the pedicel not projected outerly. All the species are redescribed, illustrated and keyed. The males of Assycuera scabricollis and A. rubella are described for the first time. The key presented by Monné & Napp (2000b) for the Neotropical genera of Ancylocerina is modified in order to include the new genus.
