(females of B. australis unknown)
1 Mesonotum at each side with oblique line of punctures and setae running from antero-lateral angle towards midline, and reaching posteriorly beyond middle of scutum (Figs. 4, 5, 8, ols); with no punctures along anterior margin of scutum. Mesopleural line of setae (Fig. 11, mls) arcuate backwards in front of pronotal lobe; forming densely punctate band on middle of mesopleuron, which is connected by a few or no punctures with line of setae in front of mid coxa ............................................................................................................................................................................... 2
- Mesonotum without oblique line running towards center of scutum; with few punctures and setae along anterior margin of scutum, either in a row or dispersed. Mesopleural line of setae interrupted or rather straight in front of pronotal lobe; middle of mesopleuron variable.................................................................................................................. 3
2 Proximal tooth of mandible basally thickened (Fig. 3). Scape, most of legs except tarsi, and basal four metasomal terga black (Figs. 5, 7) ............................................................................................................................ B. chubutinus - Proximal tooth of mandible not thickened (Figs. 1, 2). Scape, most of legs except tarsi, and all metasomal terga light brown (Figs. 4, 6) .............................................................................................................................. B. riojanus n. sp.
3 Mandible with three teeth, middle tooth close to proximal tooth and displaced internally. Mesopleural line of setae forming dense band with coalescent punctures all way from upper end of meso-metapleural suture to area in front of mid coxa.............................................................................................................................................................. B. gayi
- Mandible with two teeth, or with three evenly spaced teeth in a row. Mesopleural line of setae in front of pronotal lobe not forming a band, but with punctures more or less in a row to absent ............................................................. 4
4 Mandible with three teeth; proximal tooth blunt, of similar size or slighly smaller than middle tooth. Mesopleural line of setae in front of pronotal lobe with punctures forming continuous row. Metasoma with dark spots on second to fifth tergum, or unifomely light brown ................................................................................................................... 5
- Mandible with two teeth, or if three, proximal tooth pointed, larger than reduced middle tooth. Mesopleural line of setae in front of pronotal lobe indicated by a few spaced punctures to absent. Metasoma with dark spots on second tergum only ................................................................................................................................................................. 6
5 Length 4.7–5.0 mm. Metasoma uniformely pale yellowish-brown. Setae on antennal scape, head, and dorsum of mesosoma whitish ................................................................................................................................. B. cordobensis
- Length 6.0–9.0 mm. Metasoma reddish brown, second to fifth terga with dark lateral spots. Setae on antennal scape, head, and dorsum of mesosoma brown to black ................................................................................. B. wagenknechti
6 Mandible with two teeth. Mesopleural area behind line of setae finely sculptured ................................ B. bidentatus
- Mandible with three teeth. Mesopleural area behind line of setae smooth, polished ............................ B. subandinus
