Typified names:

Meganisoptera Martynov 1932

NOMEN: Meganisoptera Martynov 1932: 17 [A.V. Martynov . New Permian Palaeoptera with the descussion of some problems of their evolution. - , (1931) 1930, 1: 1-44]

ORIGINAL LISTED MEMBERSHIP (Martynov 1932): Meganeuridae Meganeura

SENIOR CIRCUMSCRIPTIONAL SYNONYMS:

= Meganeuroptera Tillyard 1918 (non Crampton 1916)

= Prototyloptera Crampton 1924

= Protaeshnoptera Crampton 1928

JUNIOR CIRCUMSCRIPTIONAL SYNONYM:

= Meganisopterida Carpenter 1939

TYPIFIED NAME IN BASIC FORMAT: Meganeura/fg [f:1906; g:1885]

TYPIFIED NAMES IN USE: Meganeuridae, Meganeuromorpha, Meganeurina, Meganeurida

MODERN STATUS: the valid (while not the oldest) name of a generally accepted, extinct plesiomorphon.
Meganisoptera s.l. (including Eomeganisoptera and Geroptera) is probably paraphyletic; Meganisoptera s.str. is possibly holophyletic (Bechly 1996).
Systematic position of Meganisoptera:

the most pessimistic classification (Kluge 2000):
Odonatoptera, or Odonata s.l. (Libellula/fg1)
  Meganisoptera s.l. (Meganeura/fg1)
 
  Geroptera (Eugeropteron/fg1)
 
  Eomeganisoptera (Erasipteron/fg1)
 
  Meganisoptera s.str. (Meganeura/fg2)
 
Protanisoptera (Ditaxineura/fg1)
 
Triadophlebioptera (Triadophlebia/fg1)
 
Protozygoptera (Kennedya/fg1)
  Neodonata, or Odonata s.str. (Libellula/fg2)
    Zygoptera
    Anisopteroides
the most optimistic classification (Bechly 1996):
Odonatoptera, or Odonata s.1 (Libellula/fg1)
  Geroptera (Eugeropteron/fg1)
  Nodonatoptera, or Odonata s.2 (Libellula/fg2)
    Eomeganisoptera (Erasipteron/fg1)
    Euodonatoptera, or Odonata s.3 (Libellula/fg3)
 
    Meganisoptera s.str. (Meganeura/fg1)
 
    Odonatoclada, or Odonata s.4 (Libellula/fg4)
 
    Campyloptera/fg1
      Lapeyuria/fg1
 
    Nodialata, or Odonata s.5 (Libellula/fg5)
 
      Protanisoptera (Ditaxineura/fg1)
 
      Discoidalia, or Odonata s.6 (Libellula/fg6)
 
        Triadophlebioptera (Triadophlebia/fg1 or Triadotypus/fg1)
 
        Stigmoptera, or Odonata s.7 (Libellula/fg7)
 
          Protozygoptera (Kennedya/fg1)
            Neodonata, or Odonata s.8 (Libellula/fg8)
              Tarsophlebia/fg1
              Odonata s.9 (Libellula/fg9)
                Zygoptera
                Anisopteroides

COMMENT. Sometimes  this taxon is wrongly named Protodonata. Initially the family Protodonata Brongniart 1885
was established for a single genus Protagrion, while the genus Meganeura was placed to another family, named Sthenaropterida. Later (Lameere 1900, Handlirsch 1906-1908) to the taxon Protodonata were added Meganeura and other insects, recently attributed to Meganisoptera. Recently Protagrion is not regarded to be close to Meganeura, and is attributed not to Odonatoptera, but to Protorrhynchota (Martynov 1932, Carpenter 1943, 1962, Bethoux & Nel 2003, et al.); the usage of the name Protodonata for the taxon which includes Meganeura and does not include Protagrion, contradicts to its original circumscription. The name Meganisoptera is widely accepted for this taxon. The name Meganeuroptera Tillyard 1918 (from words "Meganeura" and "ptera") is older, but at the same time is peoccupied, because the same name Meganeuroptera Crampton 1916 (from words "mega" and "Neuroptera") was given for the taxon Corydalus/f1=Chauliodes/g1. The names Prototyloptera Crampton 1924 and Protaeshnoptera Crampton 1928 were given as synonyms of "Protodonata" in unknown sense, so they can be only presumably attributed to this taxon.
