TAXONOMIC STATUS: B. menchuae was described from a single location and, on the basis of the worker and male I have examined so far, appears to diverge from B. macgregori only in colour pattern. Until more evidence to the contrary is available from critical studies of patterns of variation, I shall treat them as parts of a single variable species.

DISTRIBUTION: S Nearctic Region.
