A revision of Acrometopia Schiner and closely related genera (Diptera: Chamaemyiidae).

Abstract

The species of the genus Acrometopia SCHINER; all the New World species previousliy placed in the genius are transferred to the genus Toropamecia gen. nov., with the following new combinations: Toropamecia australis (Malloch), T. maculata (Coquillett), T. punctata (Coquillett) and T. reticulata (Johnson). In addition twelve new species are described. Toropamecia hendeli is proposed as a replacement name for Toropamecia reticulata (Hendel). The genus Parapamecia is erected for a single species Parapamecia intacta spec. nov and a new species Acrometopia setosifrons, from Nepal, is described. Keys a provided to the genera of the tribe Chamaemyiini, and to the species of Acrometopia and Toropamecia.
