Systematic position of Permoplectoptera:

Panephemeroptera, or Ephemeroptera s.1 (Ephemera/fg1)
 Protephemeroidea (Triplosoba/fg1)
  Euephemeroptera, or Ephemeroptera s.2 (Ephemera/fg2)
    † Permoplectoptera (Protereisma/f1=Phtharthus/g1)
    Euplectoptera, or Ephemeroptera s.3 (Ephemera/fg3)

COMMENT.  The older name Protereismephemeridae, being non-typified, by its form resembles typified names, such as Protereismatidae (i.e. Protereisma/f) and Ephemeridae (i.e. Ephemera/f). Because of this, its junior circumscriptional synonym Permoplectoptera is preferable.
