REMARKS

This newly designated family is simply conceived in order to validate the family name under the Code. This family name is derived from the genus name Ximolzas Dumitrica 2007 , replacing the junior homonym name: Zamolxis Dumitrica, 1982 ( Dumitrica 1982b) . The family name “Ximolzasinae” appeared in O’Dogherty et al. (2009b, 2011) and Bragina (2016). The family name was published in O’Dogherty et al. (2009b: 218) as “ nomen correctum herein”; however, the nomen correctum act is not defined in the English versions of any historical codes ( Blanchard et al. 1905; ICZN 1926, 1964, 1985, 1999; Schenk & McMasters 1956) or previous rules of zoological nomenclature ( Strickland 1878; Melville 1995). This word appeared in an instruction book as a “change of spelling, e.g., -somidae to -somatidae because of [an] incorrect spelling of [the] stem form” for “ nomen correctum ” act (e.g., Winston 1999:142, table 7.1). Thus, the “ nomen correct ” act cannot be read as “new replacement name” (or nomen novum). Legal acts for name published after 1999 is mentioned in Article 16 (“every new name published after 1999, including new replacement names (nomina nova), must be explicitly indicated as intentionally new”). In addition (Article 16.2), it requires, as an inevitable act, that “a new family-group name published after 1999 must be accompanied by citation of the name of the type genus.” Article 16 not only includes the “new family” but also the “ nomen novum ” (see Recommendation 16A”) the Article 16.2 also includes the “ nomen novum ” for family. The skeletal architecture of Neogene taxa belonging to the Ximolzidae Dumitrica , nom. nov. has only been illustrated for Protoscenium ( Nishimura & Yamauchi 1984: pl. 23, fig. 6?; Sugiyama 1992c: pl. 22, fig. 5). The taxonomic position of Rhabdolithis is still in discussion.

VALIDITY OF GENERA

Rhabdolithis

Xiphostylomma is clearly the same genus as Rhabdolithis . Campbell (1954) did not consider Rhabdolithis .
