Abstract

Dolichostylus gen. nov., a new genus of Portanini, is described, and illustrated, based on two new species: Dolichostylus amazonicus gen. et sp. nov. from Brazil and Ecuador and Dolichostylus zahniseri gen. et sp. nov. from Ecuador. The new genus differs from other portanine genera in having the crown short and rounded, forewing without m-cu2 vein, connective H-shaped, style very long and slender, aedeagus with pair of elongate caudoventral processes, female sternite VII longer than wide and first valvula of ovipositor without a distinctly expanded area.
