Type species.

Ceresinoidea zacki sp. nov.

Diagnosis.

Forewing with cells R2+3 and M, and 2 m-cu crossveins (Fig. 5 ); pronotum with suprahumeral spines directed laterally and slightly posteriorly (Figs 6-8 , 10 ), distally attenuate posteriorly (Figs 5 , 10 ).

Head. Vertex glabrous, without ridges or rugae, slightly concave especially at lateral margins and around ocelli; ocelli circular, slightly closer to eyes than to each other; dorsal margin weakly convex but not attaining dorsal margin of eye, which is elevated (Figs 6 , 8 ); frontoclypeus apically rounded, its sutures arched to mid-point. Pronotum. Smooth, glabrous, elevated, strongly convex in lateral view, with acute suprahumeral spines. Wings. Forewing (Figs 5 , 9 ) with 2 adjacent discoidal cells (R2+3 and M), 2 m-cu crossveins. Hind wing with 1 r-m and 1 m-cu crossvein, with forked anal vein. Legs. Metathoracic tibia with cucullate setae in row I double, row II and row III complete and single.
