Age estimates for the Latah Formation span the Burdigalian-Langhian-Serravallian (Miocene). Based on an electron microprobe analysis of Fe and Ca content in ash samples, Nash and Perkins (2012) correlated the previously undated Latah Formation to the well-dated lower Bully Creek Formation (also dated by electron microprobe analysis), and thus establish an absolute age of 15.8-15.5 Ma (Langhian).

This is a fossil that is assigned to the genus Epophthalmia, which has been recovered by Ware and Ballare (unpublished data) within the family Macromiidae. Synapomorphies supporting this assigning of the fossil wing include the presence of more antenodal crossveins than Macromia, or Didymops, which are all sister taxa to Epophthalmia. Additionally, the anal loop in this fossil more closely resembles to Epophthalmia than any of the other members of Macromiidae (Lewis, 1969). Nel and Paicheler (1994) considered the attribution to the recent genus Epophthalmia as probable.
