Holotype: ♀ in BMNH (examined). BRAZIL, Nova Teutonia, 27°11'S, 52°23'W, 26.iv.1938, Fritz Plaumann, B.M. 1938-682.
Diagnosis. It belongs to the annulicornis species-group, and can be separated from other species within that group based on metasoma almost entirely dark brown (except for laterotergites 1 and 2), T2 shape, and relatively long ovipositor sheaths (as long as metatibia).
Comments. Only the holotype specimen is known.
