B. trisanale is found in Bolivia, Brazil, Colombia, Ecuador, and Peru.
There are three elongate parallel anal plates, to which the specific name refers.
[2] Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Bachia.
The subspecific name, abendrothii, is in honor of German arachnologist Ernst Robert Abendroth (1810–1871).
