2.4. Delphacoidea Leach, 1815

- Cixioïdes sec. Spinola, 1839: subfamily: 202 [Cixcoïdes (sic!): 204. Including ‘Cixioïdes’+‘Delphacoïdes’ ( Spinola, 1839: 329)]

- Cixioidea Latreille, 1807 sec. Bourgoin & Szwedo, 2022: superfamily: 952 [for Cixioidea Spinola, 1839 (sic!), Cixiioidea (sic!), corrected here as Delphacoidea Leach, 1815].

Type-genus: Delphax Fabricius, 1798

Type-species: Cicada crassicornis Panzer, 1796: 19 [by subsequent designation, ICZN, 1961: 246]

Chronostratigraphic occurrence: Lower Cretaceous, Barremian (129.4±1.5 Ma to present). Oldest known fossil occurrence: Barremixius petrinus (Fennah, 1961) .

Composition:

2.4.1. Cixiidae Spinola, 1839

2.4.2. Delphacidae Leach, 1815

2.4.3. Lalacidae Hamilton, 1990

Note. Delphacida was formally described by Leach (1815: 125) with type genus Delphax , as a separate group of taxa from other planthoppers. Cixioïdes was formally described by Spinola (1839) in family ‘Fulgorites’ as a subfamily, including Delphax and other delphacids that he separated as a subunit within ‘Cixioïdes’ he called ‘Delphacoïdes’ ( Spinola, 1839: 329). This higher taxon was therefore proposed for the first time by Spinola, but its name should follow ICZN Art. 23.3 of Principle of Priority and formed on Delphacida Leach, 1815.
