Antennae 8-segmented, III with 1 sensorium, IV with 2 sensoria. Head as wide as long, without long postocular setae; ventrally with labrum and clypeus fused together. Pronotum with only 2 pairs of major setae; prosternal ferna large. Fore tarsus without tooth. Mesonotum with no sculpture medially. Fore wing narrow but swollen at base, without duplicated cilia. Pelta weakly sclerotised, tergites II–VII each with 1 pair of sigmoid wing-retaining setae but these arise near the midline and are directed posteriorly; tergite IX setae S1 & S2 capitate; tube shorter than head.
