COMMENTS. Some authors wrongly use for Megaloptera junior typified name(s) Sialis/fg [f: Sialida Leach 1815; g: Sialis Latreille 1802, typus Hemerobius lutarius Linnaeus 1758]: Sialidae, Sialina, Sialidiformes, Sialidae, Sialides, Sialoidea, Sialida.

Kluge 2010 BioNomina Dual-Nom :

Currently the taxon consisting of Eumegaloptera and Nothomegaloptera is usually called “Megaloptera”, the name also used sometimes to refer to the taxon Eumegaloptera + Nothomegaloptera + Rhaphidioptera (Tillyard 1918, Hennig 1953, Mickoleit 1969, Hinton 1981). Originally the name Megaloptera Latreille 1802 was proposed for a family consisting of the genera Chauliodes, Corydalus, Sialis, and Raphidia, and fitting Emmenognatha Börner 1904 in circumscription. Later on, Latreille (1807, 1810, 1825) called “Megaloptera” a smaller taxon consisting of Chauliodes, Corydalus, and Sialis only, i.e. what was later named Meganeuroptera Crampton 1916. As the name Megaloptera is currently used both ways of which only the first is circumscriptionally correct, its extensive alternative use is misleading. Burmeister (1839) used the name “Megaloptera” for Birostrata.

The oldest circumscriptional name whose original circumscription fits the taxon that includes Eumegaloptera and Nothomegaloptera but excludes Rhaphidioptera is Meganeuroptera Crampton 1916. It is derived from ‘mega’ + ‘Neuroptera’ and should be not confused with its junior homonym Meganeuroptera Tillyard 1918 (derived from ‘Meganeura’ + ‘ptera’) (see below).

ORIGINAL LISTED MEMBERSHIP (Burmeister 1839): Hemerobiidae Hemerobius  + Myrmeleontidae Myrmeleon

= Euneuropteroidea

TYPIFIED NAME IN BASIC FORMAT: Myrmeleon/f=Hemerobius/g (sine Raphidia,Chauliodes) [f:1802; g:1758(gen.210)]

MODERN STATUS: non-valid, junior homonym of Megaloptera Latreille 1802, synonym of Birostrata; belongs to a generally accepted, holophyletic taxon. Systematic position of Birostrata:

  Birostrata (= Megaloptera Burmeister 1839)


The formal original circumscription of the name Megaloptera Latreille 1802 is Rhaphidioptera + Meganeuroptera, but in modern literature it is often used for Meganeuroptera without Rhaphidioptera. In order to avoid confusion, we propose not to use the name Magaloptera, and instead it use the following names:

instead Megaloptera sensu Latreille 1806 - Meganeuroptera Crampton 1916;

instead Megaloptera sensu Latreille 1802 - Emmenognatha Borner 1904;

instead Megaloptera sensu Burmeister 1839 - Birostrata Kluge 2005.
