A comprehensive study of an Upper Cretaceous (Coniacian) siliceous sponge fauna from Bornholm, Denmark was conducted by Brückner (2006), with three new genera and 18 new species described. Among them, the monotypic euplectellid genus Walteriella Brückner, 2006 and its type species Walteriella plectilis Brückner, 2006 were established based on the following unique characteristics: choanosomal diactines and rare hexactines, missing hypodermalia, autodermal hexactines, and supradermal hexactines and pentactines. The genus name Walteriella was derived from the morphologically similar extant euplectellid genus Walteria Schulze, 1886 from the Western Pacific, South Australia, and the Indian Ocean (Brückner, 2006; Tabachnick et al., 2019).
However, Walteriella Brückner, 2006 was recently found to be a junior homonym of Walteriella Kazantsev, 2001, a genus of Asian soldier beetles comprising ten species (Kazantsev, 1999; Kazantsev, 2001; Švihla, 2004; Okushima, 2008; Satô et al., 2014). Walteriella Brückner, 2006 is therefore invalid due to homonymy and needs to be replaced according to the International Code of Zoological Nomenclature (ICZN). In recognition of the original author of Walteriella Brückner, 2006, Dr. Anke Brückner, and her extensive contributions to the paleontology of hexactinellid sponges (Brückner, 2006), we here propose Bruckneria nom. nov. (gender feminine) as a new replacement name for Walteriella Brückner, 2006. The type species Walteriella plectilis Brückner, 2006 is therefore transferred to Bruckneria as Bruckneria plectilis (Brückner, 2006) comb. nov. The holotype (SMF XXVI 362: Figure 1), including both a part (SMF XXVI 362a) and counterpart (SMF XXVI 362b), is currently housed at the Senckenberg Museum of Natural History in Frankfurt, Germany. The publication and nomenclatural acts herein are registered under ZooBank LSID urn:lsid:zoobank.org:pub:F8EDB286-64B8-4125-907E-4863368BF2DA and urn:lsid:zoobank.org:act:ECD2231A-81F0-4206-B9E4-41B8076DCA7B.
Notably, Walteriella is a popular name in nomenclature, and Walteriella Brückner, 2006 is not the first junior homonym of Walteriella Kazantsev, 2001 (Arthropoda) to be discovered. Mendoza-Palmero and Hsiao (2020) addressed the homonymy of Walteriella Mendoza-Palmero, Mendoza-Franco, Acosta and Scholz, 2019 (Platyhelminthes), a genus of gill parasites found in South American catfishes (Mendoza-Palmero et al., 2019), and proposed Boegeriella Mendoza-Palmero and Hsiao 2020 (Platyhelminthes) as a new replacement name. Furthermore, the genus name Walteriella Kazantsev, 2001 (Arthropoda) is itself a replacement name for Walteria Kazantsev, 1999 (Arthropoda), which was preoccupied by Walteria Schulze, 1886 (Porifera) (Kazantsev, 2001). Both Walteria and Walteriella (e.g. Walteria Kazantsev, 1999 [Arthropoda], Walteriella Brückner, 2006 [Porifera], and Walteriella Mendoza-Palmero, Mendoza-Franco, Acosta and Scholz, 2019 [Platyhelminthes]) should be avoided in future zoological nomenclatural acts.
