Resumen

Three new genera in Acutalini are described, all of which have two discoidal cells (R2+3 and M) in the forewing, as in Euritea Stål. Osaria quadrilinea n. gen. et n. sp. differs from other acutalines in having a pair of suprahumeral spines and a strongly convex pronotum in lateral view. It differs from O. zacki, n. sp., in having an evenly convex, rather than stepwise convex pronotum in lateral view, in addition to other details. Quinquespinosa septamacula n. gen. et n. sp. differs in having three posterior pronotal spines. Tectiforma guayasensis n. gen. et n. sp. has the pronotum strongly tectiform throughout. //add distro gf geera A key to all genera of Acutalini is provided
