Prelude to a study of the feather mites of Australia (Acariformes: Astigmata) Author HALLIDAY, R. B. text Zootaxa 2023 2023-05-09 5280 1 1 73 http://dx.doi.org/10.11646/zootaxa.5280.1.1 journal article 54455 10.11646/zootaxa.5280.1.1 a3384e49-2a34-4e14-8651-90cd896e0df4 1175-5326 7912198 E89D81FE-D079-41B7-9FF4-4933D620B89D Genus Bdellorhynchus Trouessart & Mégnin, 1884 Bdellorhynchus Trouessart & Mégnin, 1884b: 156 . Bdellorhynchus Mégnin & Trouessart, 1884a: 138 . Bdellorhynchus Trouessart & Mégnin, 1885a: 79 Bdellorhynchus Trouessart, 1885b: 109 . Type species: Bdellorhynchus polymorphus Trouessart & Mégnin, 1884c: 50 , by monotypy (in Trouessart 1885b, Trouessart & Mégnin 1885a ). Notes : Gaud & Atyeo (1996a: 170) referred to the new generic names proposed in Trouessart & Mégnin (1884b: 156) and Mégnin & Trouessart (1884a: 138) as nomina nuda . In both papers, the genus Bdellorhynchus is diagnosed in a key to genera, so it is not a nomen nudum for that reason. It lacks a type species there, but new genera proposed before 1930 were not required to have a type species (ICZN Article 13.3).
