Vertex slightly convex, corners rounded. VOL 0.36 X HE. Temples divergent anteriorly.

Propodeal disc 0.9 X as long as wide, 1.48 X as long as high, basal triangle with irregular striae, propodeal disc with longitudinal striae, median carina complete, posterior carina concave, well defined declivity, lateral of propodeum predominantly polished and shining. Mesopleuron polished, punctures as frons, more strongly punctured around the callus which is elongated, polished and ill defined. Fore wing with discoidal vein spectral, weakly pigmented at the base, interstitial with median vein.

PARATYPES: BRAZIL, Espírito Santo, 2 males, Santa Teresa, Estacao Biologica de Santa Lucia , 23.II-28.IIII.2001, sweeping, C.O. Azevedo & R. Kawada col.

Discussion.- This species curiously resembles the genus Apenesia by the texture and appearance of clypeus and head.

Etymology.- The specific epithet refers the similarity to Apenesia species. Distribution.- Brazil ( Espírito Santo).
