Abstract: Megaloptera is a rather species-poor ingroup of Holometabola.Its representatives include fishflies, alderflies and dobsonflies (Cover & Resh 2008, Cover & Bogan 2015, Heckman 2017).About 400 species of Megaloptera are known from the extant fauna (Cover & Resh 2008).Extant megalopterans are generally differentiated into two major ingroups: Sialidae Leach, 1815 and Corydalidae Van der Weele, 1910(Cover & Resh 2008).All adult mega lopterans have prominently equal-sized wings.Adult dobsonflies (Corydalinae, ingroup of Corydalidae) are conspicuous by their huge protruding mandibles, probably involved in sexual (female) choice, as well as a very large body size and wingspan, reaching 180 mm (Cao & Liu 2013, Heckman 2017).The monophyly of Megaloptera was brought into question several times in recent years based on molecular (Winterton et al. 2010) and morphological data (Beutel & Friedrich 2008, Beutel et al. 2013).Yet, most of the contemporary sources do agree that Sialidae + Corydalidae is a monophyletic group, i.e.Megaloptera, which is either the sister group to Neuroptera + Raphidioptera or only to the former (Wang &
