Note 1: It is not possible to separate B. pseudolignosa (Breuning, 1942), B. parva (Fisher, 1938), and B. zeteki (Fisher, 1947) (Fig. 69) from B. elongata (Fig. 70). Apparently, they are all synonyms, and were not included in the key. It is also possible that B. cuprina is also synonym of B. elongata .

Note 2: There are specimens agreeing with B. cuprina with outer angle slightly projected, as well as specimens with outer angle not projected. The specimens with outer angle projected were not included in the key.

Note 3: It is not possible to separate B. lignosa and B. occulta . They probably are a single species, and were not included in the key.

Note 4: Apparently, B. puncticollis (Fisher, 1947) and B. leo Monné & Monné, 2009 are synonyms of B. mexicana, and were not included in the key.
