The Valkerella - Walkerella - Walkerana case A rather complex nomenclatural situation concerns ten zoological generic nomina, in three different zoological groups (HYMENOPTERA, ORTHOPTERA, ANURA), which are connected by homonymy and neonymy (relationship between new replacement nomina or neonyms and the nomina they replaced or archaeonyms; see Dubois 2000, 2006). They are presented below in the chronological order of their publication. For each of them, two websites, namely the online version of the Nomenclator Zoologicus [http://uio.mbl.edu/NomenclatorZoologicus/] and Zoobank [http://zoobank.org/], were surveyed in order to see whether and which, if any, information was provided about it on 5 October 2016.
