It was first identified by Ferdinand von Mueller as possibly a new species or variety in the early 1890s, noting it as "U. albiflora or a closely allied species."

Mueller labeled one herbarium sheet as Utricularia albiflora var.

Without a valid description, according to the rules of botanical nomenclature, however, the epithet quinquedentata was not recognized until Peter Taylor validly published the species in 1986.
