Name

Rhachisaurinae Pellegrino, Rodrigues, Yonenaga-Yassuda & Sites Jr, 2001: 330

Type genus: Rhachisaurus Pellegrino, Rodrigues, Yonenaga-Yassuda & Sites Jr., 2001, by monotypy.

Nomenclatural note: proposed by Pellegrino et al. (2001) to include the monotypic genus Rhachisaurus, but was not explicitly diagnosed by a list of characters (Article 13.1.1). Under Article 13.1.2, a diagnosis may consist of "a bibliographic reference to such a published statement." Although Rhachisaurinae was not explicitly diagnosed in words, Pellegrino et al. stated "Content: Rhachisaurus, new genus for Anotosaura brachylepis Dixon, 1974." Article 13.5 allows the combined description of a new family name and new genus name as long as the type species is fixed. Thus, Rhachisaurinae is available, with type genus Rhachisaurus, and type species Anotosaura brachylepis Dixon, 1974, the latter by monotypy (Article 68.3). (Colli et al. 2015)
