Diagnosis.

The original description of the species gave insufficient detail to distinguish it from other species. Head wider than long, without indentation; metasomal petiole punctate and without bulging, widening a little back and forth, then truncated right to its articulation, and carrying two insensitive tubercles in front of its middle; S2 bell-shaped, but very short, appreciably wider than long, strongly swollen above and below, and offering at its posterior edge a strong duplication of the teguments; second cubital cell strongly narrowed towards the radial and prolonged at its posterior border, but at its external angle; antennal hooks very small; scape yellow beneath; pronotum anteriorly with a yellow, narrow, perfectly regular and medianly interrupted band, and each of T1-T2 and S2 with a yellow apical band; legs ferrugineous, with some parts of femora and mid tibia black (de Saussure 1855; van der Vecht 1935).
