Material examined. Holotype ♂: PERU, [Huanuco], Tingo Maria, 620 m, 5–12.X.1964, C. C. Porter col. ( MCZH, #31252). Allotype ♀: PERU, Cuzco, Quincemil, 750 m, 5–16.XI. [19]62, L. Peña col. ( MCZH, #31252).

Diagnosis. FEMALE ( Fig. 141 ). Black. Mandible wide apically, with five teeth ( Fig. 142 ). Clypeus with subangulate median lobe. Antennal scrobe not carinate. Frons coriaceous. Vertex convex. Pronotal disc with anterior corner angulate; anterior carina thick, inner margin irregular; median carina extremely weak, near imperceptible; lateral margin acute but not carinate; posterior margin paralleled by series of punctures. Scutellar pit transverse. Mesopleuron with subtegular groove wider anteriorly; anterior fovea rounded; upper fovea subrounded, margins undefined; lower fovea with upper margin absent ( Fig. 143 ).

MALE ( Fig. 144 ). Black. Mandible with five apical teeth ( Fig. 145 ). Clypeus with angulate median lobe. Antennal scrobe wholly carinate. Frons coriaceous. Vertex slightly convex. Temple carinate. Pronotal disc with anterior corner angulate and prominent; anterior carina straight and sharp, inner margin slightly irregular; median carina weak, touching posterior series of fovea; lateral margin subcarinate on two anterior thirds; posterior margin paralleled by small foveae; side of disc with ventral margin carinate. Scutellar pit rounded. Mesopleuron with upper fovea rounded. Genitalia ( Figs 144, 145 ): paramere wide, about as long as basiparamere, apex rounded, dorsal and ventral margins almost convex; cuspis shorter than paramere, deeply divided into two arms, dorsal arm shorter and wider than ventral arm; aedeagus bottle-shaped, apical half progressively narrow apically, ventral surface with conspicuous projection ventrad; apodeme wholly dilated.
