Hernáez et al. (2020) described a new fossil species of ghost shrimp, Callichirus santensis, from the Upper Pleistocene Cananéia Formation, southeast Brazil. The article in which C. santensis† was originally proposed was published online only (Hernáez et al., 2020), but did not include a ZooBank registration number (LISD), required for validation of the new names in electronic-only publications [vide Art. 8.5.3 of the amended Code of the International Commission on Zoological Nomenclature (ICZN, 1999, 2012)]. Therefore, the present note serves to validate the name Callichirus santensis by fulfilling the ICZN conditions for nomenclatural availability.
