| Comment | Type 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). |
| Etymology | Named 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] The genus was named after Greek Euros (Εὖρος), the East wind + Greek lophos (λόφος), crest of hill, ridge + Greek sauros (σαῦρος), lizard. ["...Greek: Euro- (eastern), lopho- (ridge), sauros (lizard), referring to the association of this group of species with the Serra da Espinhac¸o ridge of mountains in eastern Brazil…"]. |
