Superfamily ELLIPSOCEPHALOIDEA Matthew, 1887

REMARKS

Assignment of the Ellipsocephaloidea to a higher level systematic rank is problematical. Many authors include them in the Redlichiina ( Geyer 1990; Kaesler 1997: 429; Adrain 2011), whereas according to Fortey (1990) at least some ellipsocephaloids should be grouped among the Ptychopariina Richter, 1932 (see also Kaesler 1997: 302). Recently, Adrain (2011) suggested to abandon the suborder Ptychopariina Richter, 1932 and the order Ptychopariida Swinnerton, 1915 .
