Material examined. Holotype ♂ of B. polita : BOLIVIA, [Provincia La Paz], Coroico ( MCZH, #30805). Holotype ♂ of B. vicina , BOLIVIA, Cochabamba, 109 km, E. Cochabamba, cloud forest, 1400 m, 17º8'52''S 65º42'54''W, 1–6.II.1999, F[light] I[nterception] T[rap], F. Génier. col. ( CNCI).

Diagnosis. MALE ( Fig. 113 ). Black. Mandible with five apical teeth ( Fig. 114 ). Clypeus with rounded or subangulate median lobe. Antennal scrobe wholly carinate. Frons polished. Vertex convex. Pronotal disc with anterior corner angulate; anterior carina high and sharp; median carina absent; lateral margin acute but not carinate; posterior margin not paralleled by fovea. Scutellar pit transverse. Mesopleuron with subtegular groove wide; anterior fovea subrounded; upper fovea ovoid; lower fovea with upper margin absent on median third, lower margin sometimes undefined ( Fig. 115 ). Genitalia ( Figs 116, 117 ): paramere slender and elongate, 2. 0 × as long as basiparamere, inserted into it only dorsally, apex rounded, dorsal margin convex and ventral margin concave; cuspis about as long as half length of paramere, divided into two arms, dorsal arm shorter and wider than ventral arm; aedeagus not bottle-shaped, progressively narrow apically; apodeme short, wholly wide, ventral surface with conspicuous projection ventrad; base angled outward.

FEMALE ( Fig. 118 ). Black. Mandible with five apical teeth ( Fig. 119 ). Clypeus with obtusely angulate median lobe. Antennal scrobe not carinate. Frons weakly coriaceous. Vertex convex. Pronotal disc with anterior corner angulate; anterior carina thick and arched forward medially; median carina absent; lateral margin not carinate, but acute; posterior margin paralleled by series of small foveae. Scutellar pit transverse. Mesopleuron with subtegular groove almost evenly wide; anterior fovea subquadrate; upper fovea subrounded, central pit deep; lower fovea narrow fully outlined ( Fig. 120 )

Distribution. Brazil (Amapá, Pará, Mato Grosso), Peru, Bolivia.

Remarks. Azevedo et. al. (2005) described B. vicina based on a very unusual shape of paramere, unique for Bakeriella . Now we had opportunity to revise the holotype of B. polita and realized that both species are essentially the same, and considered the former as junior synonymous of the latter.
