Diagnosis.

Male antennae pectinate, except 2 proximal and more than 3 distal simple antennomeres, branch of 1st flagellomere short, with only one dentate process. Wings broad, generally with numerous dark markings; costal area broad with crossveins simple except several ones forked; subcostal area obviously narrower than costal area, having several crossveins; more than 5 crossveins between R and Rs, MA fused with R at wing base, proximally with no crossvein connecting to MP, and arising from R prior to separation between R and Rs; MP with 2 main branches; nygmata present; trichosors present along wing margin. Male ninth tergite in dorsal view with a truncate or arcuate anterior incision and a deeply V- or U-shaped posterior incision, leaving a pair of broad hemitergites, which are obtuse distally and densely haired. Male ninth sternite generally much shorter than ninth tergite. Male ectoproct highly specialized, largely covered by ninth tergite, without callus cerci and any macrosetae. Male gonocoxite complexes 9, 10 and 11 comprising two pairs of sclerites (i.e. ninth and tenth gonocoxites) and a transverse sclerite (i.e. gonarcus = eleventh gonocixites); gonarcus laterally connecting to bases of ninth gonocoxites. Hypandrium internum generally trapezoidal, with lateral margins slightly arcuate.
