Notorhinus Moritz & Parra-Gómez, 2023 (Siphonophorida: Siphonorhinidae) junior homonym of Notorhinus Roth, 1903 (Mammalia: †Astrapotheria: incertae sedis): proposed substitution by Notiorhinus nom. nov.

Abstract

The genus Notorhinus Roth, 1903 was originally used for an extinct genus of mammal from Argentina. Notorhinus Roth, 1903 includes the two species Notorhinus haroldi Roth, 1903 and Notorhinus denticulatus Roth, 1903, both described based on a single fossil molar tooth each (Roth 1903: 138). Simpson (1967) states that the type material of both species is lost and the identity is unclear. Interestingly, the genus name Notorhinus Roth, 1903 was also erroneously replaced shortly after its description by the name Tonorhinus Ameghino, 1904, as it was erroneously thought to be a homonym of the beetle genus name Notorhina Redtenbacher, 1845 (Ameghino 1904: 230).Unaware of its existence Moritz & Parra-Gómez ( 2023) described the monotypic millipede genus Notorhinus Moritz & Parra-Gómez, 2023 (Siphonophorida: Siphonorhinidae) with the single species Notorhinus floresi Moritz & Parra-Gómez, 2023. Therefore, the generic name Notorhinus Moritz & Parra-Gòmez, 2023, as a junior homonym is not valid and must be replaced, in accordance with the International Code of Zoological Nomenclature (ICZN 1999) article 60.
