A new genus, Terocelion gen. nov., is proposed for two new Oriental species of Keroplatidae (Diptera), T. melanoleucum sp. nov. (Thailand) and T. terezae sp. nov. (Brunei). The new genus is characterized mainly by the following characters: long and pectinate antennae, mediotergite distinctly protruding with a well developed subscutellar membranous area, wings distinctly marked and relatively narrow, vein CuA2 downcurved towards the tip, tibial trichia in regular rows, gonostylus without teeth, dorsoventrally flattened and apically rounded. A brief discussion on possible relationships to other genera of the tribe Keroplatini is also included.
