Head with occipital carina close to eyes; ocellar triangle weakly reticulate; ocellar setae III on anterior margins of triangle; only two pairs of postocular setae, median pair absent. Pronotum with anterior third boldly reticulate, blotch transversely reticulate. Metanotum with irregular linear sculpture, with some markings between the main lines. Forewing with sub-apical lobe extending beyond base of terminal seta. Tergites II–VI with no marginal comb medially. Sternites V–VI with discal microtrichia continuous medially, posterior margins medially with no craspedum; sternite VII medially with neither median discal nor marginal microtrichia.
