CommentType Species: Tropidurus nanuzae is the type species of the genus Eurolophosaurus FROST et al. 2001.

Passoni et al. (2008) suggested that “The populations of E. nanuzae from Bahia should be considered a new undescribed species, and the name nanuzae should be restricted to those of Minas Gerais (Extracão, Pedra Menina and Serra do Cipó). 
Etymologynamed after Dra. Nanuza L. Menezes, of the Departamento de Botanica da Universidade de Sao Paulo, “que por anos tem trabalhado sobre as Velloziaceas da Serra do Cipó e que me introduziu à região.” [RODRIGUES 1981]
