Belongs within: Plecoptera.
The name Grypopterygomorpha was used by Sinitshenkova (2002) for a clade of stoneflies including the modern Antarctoperlaria and its fossil relatives. They are characterised by wings with abundant cross-veins and the presence of both thoracic and abdominal gills in nymphs. Modern Antarctoperlaria are restricted to the Southern Hemisphere but stem grypopterygomorphs were more widespread with the Siberioperlidae found in Siberia and Mongolia (Sinitshenkova 2002). The Antarctoperlaria are united by the presence of a sternal rather than tergal depressor muscle for the fore trochanter (Grimaldi & Engel 2005). The Eustheniidae retain remnants of the lateral abdominal gills into adulthood (Theischinger 1991).
