Family Whetwhetaksidae Archibald & Cannings Remarks. We emend the diagnosis of Whetwhetaksidae of Archibald et al. (2021) based on the fossils described here by the following: character state 1, pterostigma at least seven times as long as it is wide (this was ten times width in Archibald et al. 2021), and remove character state 10, base to nodus percent wing length, as a synapomorphy for this group as this region is shorter in Danowhetaksa and does not now distinguish Whetwhetaksidae from Dysagrionidae or Sieblosiidae.
