Callacate, Cajamarca, Peru.
Has been considered conspecific with B. culicivorus; one set of genetic data indicates that B. trifasciatus and B. tristriatus are sister-species, and that they are sister to B. culicivorus and B. hypoleucus#R, whereas a more detailed phylogenetic study of the B. tristriatus group found that the latter comprises ten clades, one pertaining to B. trifasciatus, which is sister to B. tristriatus tacarcunae#R; integrative reconciliation of all evidence needed to resolve the situation. Race nitidior perhaps not distinguishable from nominate#R. Two subspecies recognized.
