Taxonomic notes

Martynov (1928) described and placed in the order Megaloptera the extinct family † Permosialidae, which he based on one new genus and two new species – † Permosialis paucinervis Martynov, 1928 and † Permosialis lata Martynov, 1928 . Permosialids have been treated variously as megalopterans (e.g., Martynov 1928, Martynova 1962), Neoptera incertae sedis (e.g., Carpenter 1992; Prokop et al. 2017), or † Miomoptera Martynov, 1928 (e.g., Riek 1976; Storozhenko & Novokshonov 1999; Aristov et al. 2013). In the present work, we follow Prokop et al. (2017) in treating † Permosialidae as Neoptera incertae sedis, and thus exclude it from the Megaloptera . The family currently contains three genera (PBDB 2022), of which only † Permosialis Martynov, 1928 has previously been placed in Megaloptera .
