Clypellus narrow, sides usually parallel with convex apex slightly expanded. Margin of gena next to clypellus much narrower than ocellocular area. Ocelli on anterior margin of crown, visible dorsally. Pronotum much longer than crown, lateral margins short, divergent, sometimes longer, without carina; posterior margin transverse or shallowly concave. Forewing elongate; appendix wide, extending around 1 st and 2nd apical cells; without outer subapical cell; inner subapical cell open basally; with 2 subapical cells and 4 apical cells; hindwing with 3 apical cells. Hind 1 st tarsomere base with indistinct notch ventrally.

Male genitalia. Pygofer lobe broadly or narrowly rounded posteriorly, posteroventral margin usually produced, with or without processes; with group of submarginal setae posteriorly. Subgenital plates triangular, long or short; apex fingerlike, membranous, or rarely without membranous apical extension; ventrolateral margin with uniseriate row of setae, sometimes with small sclerotized tooth present on dorsolateral margin. Style with apical process well-developed, usually strongly curved; lateral lobe well-developed, rarely reduced; basal arm very short. Connective Y-shaped, articulated with aedeagus. Aedeagus usually simple, filamentous, recurved anterodorsally, base sometimes expanded; rarely with process.
