Abstract: Genus Kaius nom. nov. urn:lsid:zoobank.org:act: 4AEC9D7A-292B-4B0F-801A-4458B6133FB4 Georgus Gómez, 2018 [J. Nat. Hist., 52(41–42): 2615–2616] (Crustacea: Copepoda: Harpacticoida: Argestidae) preoccupied by Georgus Thiele, 1893 [Geb. Sch. Beg. natür. Class., 2: 366] (Mollusca: Polyplacophora: Chitonida: Chitonidae), syn. Rhyssoplax Thiele, 1893 [Geb. Sch. Beg. natür. Class., 2: 368] (Mollusca: Polyplacophora: Chitonida: Chitonidae). Remarks. Thiele (1893: 367–368) proposed the genus Georgus for two species formerly placed in the genus Chiton Linnaeus, 1758 (Polyplacophora: Chitonida), G. rusticus (Deshayes, 1863) and G. nigrovirescens (Blainville, 1825). Some years later, Thiele (1909) synonymised these two species with C. angusticostatus Quoy & Gaimard, 1835 which was subsequently synonymised with C. mauritianus Quoy & Gaimard, 1835 by Dupuis (1918). Van Belle (1983) regarded the genus Rhyssoplax proposed by Thiele (1893), as a subgenus of Chiton, but O’Neill (1989) gave Rhyssoplax full genus status. Bullock (1988a) noted that many chitonid species from the Old World placed in the genus Chiton probably belong in Rhyssoplax, and Bullock (1988b) reallocated C. nigrovirescens into Radsia Gray 1847. At present, C. mauritianus (= G. rusticus) is accepted as R. mauritiana (Quoy & Gaimard, 1835), and the chitonid genus Georgus is currently regarded as a junior subjective synonym of Rhyssoplax (MolluscaBase eds. 2024). Despite its status, the chitonid genus Georgus remains available irrespective of its invalidity as a junior synonym (ICZN 1999, Art. 10.6). Gómez (2018) proposed the genus name Georgus for Bodinia peterrumi George, 2004 (Crustacea: Copepoda: Harpacticoida: Argestidae) and entered homonymy with the chitonid genus name Georgus. Since the chitonid genus name Georgus (Polyplacophora) remains available (see above), a new replacement name for the argestid genus name Georgus (Copepoda) is required. Here I propose the new replacement name, Kaius nom. nov., as intentionally new for Georgus Gómez, 2018 (Copepoda: Harpacticoida: Argestidae) (ICZN 1999, Art. 16.1). The prior nominal taxon, Georgus Gómez, 2018 and the new replacement name Kaius nom. nov., proposed herein, have the same type species, Bodinia peterrumi George, 2004) [= Georgus peterrumi (George, 2004)] (ICZN 1999, Art. 67.8), and should be referred to as Kaius peterrumi (George, 2004) comb. nov. The generic diagnosis of Kaius nom. nov. is the same as for the prior nominal taxon, Georgus Gómez, 2018, and is as in Gómez (2018: 2615–2616) (ICZN 1999, Art. 13.3). Etymology. The new replacement name, Kaius nom. nov., is dedicated to Dr Kai Horst George for his contribution to the knowledge of the Argestidae.
