); mouthcone short and rounded at apex with 3segmented maxillary palpi. Compound eyes more or less bulging. Ocellar setae I absent, setae III situated between hind ocelli or rarely at tangent of anterior margin of hind ocelli, and relatively long. Postocular setae uniserial and five pairs. Antennae 8 segmented, usually slender, segment I with two dorsal apical setae, III and IV with sensecone forked, III to VI with some microtrichial rows on both dorsal and ventral surfaces (cf,

). Metascutum usually smooth, often weakly sculptured medially; median pair of setae situated at or near anterior margin; campaniform sensilla present or absent. Prosternal ferna undivided. Mesosternum without sternopleural suture; endofurca with spinula. Metasternal endofurca usually without spinula. Metaepimeron with 0 to 2 setae.

Tarsi 2segmented. Abdominal terga without ctenidia or posteromarginal craspeda; terga II to VII with three setae (B3–B5 setae) along lateral margin arranged in straight line, usually smooth medially and sculptured laterally (cf.

Fig. 10
); tergum X without median split; sterna without posteromarginal craspeda, with or without discal setae; sternum II with two or three pairs of posteromarginal setae; sterna III to VII with three pairs of posteromarginal setae; laterotergites without discal setae. Ovipositor developed.
