Taxonomic notes

† Nanosialidae was originally described by Shcherbakov (2013), who included in it four new extinct genera and placed it in †Siarapha, a new suborder of Megaloptera . Shcherbakov considered †Siarapha to be transitional between Megaloptera and Raphidioptera . Here, we follow Engel et al. (2018) in treating this family, and all of its originally-included genera († Hymega Shcherbakov, 2013 , † Lydasialis Shcherbakov, 2013 , † Nanosialis Shcherbakov, 2013 , and † Raphisialis Shcherbakov, 2013 ) and species from the Russian Poldarsa Formation (Permian: Lopingian), as stem-group Raphidioptera .
