Introduction Linnaeus (1758, 1767) established the science of taxonomy and nomenclature was followed by later researchers. Later, Neuroptera specialists provided more and more detailed descriptions and compiled the first catalogues (Rambur 1842 and Walker 1853). Despite the greatest efforts and good intentions of the researchers, repeated species descriptions also happened. In 1853, Walker ranked all antiion species in one genus: Myrmeleon, which made their identification complicated. Later, in 1866, Hagen restored the earlier classification ranking the species into different genera and also provided important species revisions. His works were completed by McLachlan (1868), who continued the specific and generic revision of species listed in Walker (1853). Even in the earlier monographs, under their generic name, authors used to list literature references, together with the taxonomical changes to let us follow the changing status of the species. This practice continues today and is becoming more and more accurate. Nowadays, in the faunistic papers, not only name changes (combinations, synonyms, etc.) but numerous biological information is published like habitat, distribution, behavior, ecology, etc. In the early 20th century, the antiion research became more intensive and a high number of species were described from non-European continents. Most of these descriptions were provided by Navás. He was criticized by several contemporary authors and a high number of his species was synonymized by Banks (1913) and Esben-Petersen (1920). In the second half of the 20th century, comprehensive studies and monographs were published on the antiion fauna of various geographic areas based on thorough explorations that were done ever before. Good examples of these works are Hölzel 1972, Ghosh 1984, New 1985a,b,c, and Aspök et al. 1980. In addition, major worldwide generic revisions were published eg. Hölzel 1987, Mansell 1985, Stange 1976, etc. In the 21st century, this trend continued. For the future, revisions of genera Myrmeleon, Distoleon, Neuroleon, etc. shall be focused. In addition, the revision of the antiion fauna of smaller or larger countries shall be continued, eg. Krivokhatsky (2011). The catalogue of Myrmeleontidae by Stange (2004), is the most important subrecent work providing a new synthesis of research in antiion taxonomy. Recently online databases and web catalogues become more and more important. Lacewing Digital Library (Oswald 2019), the antiion of South Africa (Mansell 2018), Fauna Europaea (Letardi et al. 2019, etc., makes research easier.
