Status As Mortensen (1948: p. 227) discusses, von Martens (1866: p. 179) was not proposing a new genus name but changed the ending of the genus Nucleolites. Whether this was intentional (i.e. an unjustified emendation) or not this has to be treated as incorrect subsequent spelling according to ICZN regulations (Art. 33). [details]
