Diagnosis.

This species can be distinguished from the other Uruguayan species of the genus by the combination of the following character states: 1) wings yellowish with distal margin of the fore wing blackish; 2) mesosoma yellow with black marks on mesoscutum (three stripes), hind part of tegula, hind margin of scutellum, anterior margin of mesopleuron, 7-shaped mark on upper hind part of mesopleuron, a continuous anterior band along the anterior margin of metapleura, and propodeum and hind rim of propodeum; 3) metasoma yellow with tergites I-IV anteriorly broadly and posteriorly narrowly black and with posterior tergites anteriorly black; 4) laterotergite V 2.7-3.4 times as long as wide; 5) legs yellow with dorsal longitudinal black band on med and hind coxa, fore, mid and hind (except the first tarsomere) tarsi strongly infuscate, femur darkened dorsally and ventrally, and tibia infuscate proximally, tibia with close and dark pubescence, giving them a dirty yellow appearance; 6) tergite II highly polished, with very fine sparse punctures, and with anterolateral corners separated by deep oblique grooves; 7) malar space 0.3-0.4 times as long as basal width of mandibles; 8) ovipositor 1.25-1.3 times as long as hind tibia; 9) apex of ovipositor slightly compressed, with weak denticles arranged in a median row on dorsal valve, and with ventral valve not expanded laterally, with a few weak teeth.
