Scutellum almost entirely black; third antennal segment yellow; femora yellow with brown patches, tibiae and tarsi uniformly brown; first (inner) cross vein (r-m) beyond centre of discal cell; second (outer) cross-vein (dm-cu) on wing conspicuously oblique (Spencer 1963). Pale puparium with posterior spiracles each with 3 equal circular bulbs, remains in the leaf at end of the mine (Spencer 1977).
