Diagnosis.

Antenna with 12 antennomeres in both sexes; F1 nearly twice as long as apical width and about twice as long as F2. Body without patches of appressed, white setae. Mesoscutellum with subhorizontal dorsal surface about twice as long as subvertical surface, both surfaces divided by weak longitudinal median depression so that mesoscutellum is weakly biconvex, each convexity emphasized by small posteriorly directed sublateral projection that almost overhangs metanotum. Arolia present but small. Forewing with two submarginal cells (i.e., 1rs-m absent). Metasomal T1 with long cinereous setae laterally; T2 to T5 with similar setae, some of them brownish, at extreme sides; T2 to T4 with subapical bands of white setae (broken medially on T2); T1 with midlength of horizontal surface about half as long as declivitous anterior surface and about half as long as midlength of exposed part of T2.
