Minor (Canindeyli, Paraguay): proportionately small, and small-eyed; promesonotum in side view smoothly and strongly convex; almost all of dorsal surface of head carinulate and foveolate; lower half of mesopleuron smooth, remainder of meso soma almost all smooth; propodeal spines small, equilaterally triangular.
