Comments. This is another species in the subgenus Fallapion.In
addition to the characters given in the key, adults of this species may be
distinguished by characters of the polished area of the front femur,
which bears deep, coarse, well-defrned striations and has a prominent
limiting ridge. Nothing is recorded on the life history or habits of this
species. Specimens fromAlberta are labeled "ex. CarexlEleocharis," and
were likely collected in sweeps of marshs dominated by these plants.
Kissinger (1968) designated the lectotype of this species.
