Head slightly wider than long, usually slightly narrowed to base; three pairs of ocellar setae, pair I often represented by a single seta or rarely absent; ocellar setae III situated within ocellar triangle, usually long and stout; usually five pairs of postocular setae, setae II and III usually closer to each other than to I and IV. Antennae usually 8-segmented, sometimes 7-segmented, rarely 6-segmented in male; segment I with paired dorso-apical setae; segments III and IV each with forked sense-cones. Pronotum usually wider than long, with two pairs of long posteroangular setae and two pairs of posteromarginal setae. Mesonotum sculptured with transverse anastomosing striae; metascutum irregularly reticulate medially, with median pair of setae at or near anterior margin, no CPS. Fore wing first vein with long gap in setal row, 5–9 (usually 7) basal and 2 distal setae; second vein with evenly spaced many setae; posterior fringe cilia wavy; scale with five (rarely four or six) veinal and one discal setae. Meso and metasternal furca with spinula. Abdominal tergites without ctenidia; tergites II–VIII often with numerous ciliate microtrichia arising from sculpture lines lateral to S2 setae; tergite VIII with posteromarginal comb complete; sterna III–VII usually with six (II with four) posteromarginal setae, median pair of setae of VII usually in front of posterior margin; sterna often with discal setae. Males with antennal segment VI varying in length, often much longer than in female with numerous long setae; abdominal tergite IX with paired minute setae or tubercles near posterior margin; sterna without pore plates.
