Abstract
The designation of a neotype for Macrobiotus coronifer Richters, 1903 (now the type species of the genus Richtersius Pilato & Binda, 1989) by Maucci & Ramazzotti (1981) with type locality Bodø in Norway is shown to be invalid as it does not comply with the International Code of Zoological Nomenclature (Article 75.3.4). Furthermore, the specimen selected by Maucci & Ramazzotti (1981) is not from the original type locality, and the superficial and outdated documentation prevent a reliable identification of the species. A Code-compliant neotype is therefore designated. The new neotype was collected from the original locus typicus in Svalbard and described with standard light microscopy, detailed scanning electron microscopy imaging, DNA barcodes and a transcriptome, which makes it ideally suited for stabilising the taxonomy and nomenclature of Richtersius coronifer (Richters, 1903).
