Diagnosis. This species is easily recognized by the combination of the lateromedian longitudinal carinae on the propodeum, the basally pale marked hind tibia and the almost complete epicnemial carina ( Gauld, et al., 2002).

Remarks. The paratypes, at the BNHM, have the hind leg black with anterior apex of femur yellow; in Brazilian specimens the posterior apex of hind coxa and femur are yellow.

Distribution. Costa Rica, Peru, Brazil. The specimens were collected in Brazilian savannah (Assis and Itapeva) semideciduous forest (Santa Rita do Passa Quatro and Porto Ferreira) all in São Paulo State, tropical rainforest (Morretes) in State of Paraná and Amazon rainforest (Serra Norte) in Pará State.
