Head mostly with striate sculpture; three pairs of ocellar setae, pairs I and II transversely arranged in line or pair I posterior to pair II; three pairs of major postocular setae. Pronotum usually transversely striate, sometimes forming transverse reticles; three pairs of posteromarginal setae scarcely longer than discal setae; one pair of posteroangular setae usually developed; setal apex acute. Maxillary palps 3-segmented; rectangular prospinasternum. Mesonotum transversely striate. Metanotum with transverse striations on anterior half and variable reticulation on posterior half; median pair of setae behind anterior margin; campaniform sensilla absent. Mesofurca with spinula; metafurca usually without spinula. Fore wing first vein with long gap in setal row medially, and about 10 basal and two or three distal setae, second vein with complete setal row. Abdominal tergites I–VIII transversely striate laterally; posteromarginal comb of microtrichia on abdominal tergite VIII complete; median pair of setae on tergites II–VIII long and close together; tergites II–VI and usually tergite VII with posteromarginal comb of microtrichia laterally; tergite VIII with posteromarginal comb complete; tergite IX usually without campaniform sensilla, mid-dorsal setae well developed; tergite X without longitudinal split. Sternites without microtrichia, setae usually in front of posterior margin.
