|Types||Holotype: MNRJ 6536|
|Comment||Synonymy: Has been called C. ocellifer in some older publications.|
Group: this species belongs to the ocellifer group, distinguished by the presence of granules in the supraorbital semicircles, a lower number of femoral pores (less than 40), and the absence of preanal spurs (Rocha et al., 2000, Colli et al., 2003).
Type species: Cnemidophorus littoralis ROCHA, BAMBERG ARAÚJO, VRCIBRADIC & MAMEDE DA COSTA 2000 is the type species of the genus Glaucomastix GOICOECHEA et al. 2016 (but Glaucomastic FITZINGER 1843, fide TUCKER et al. 2016; however this name doesn’t seem to be mentioned by Fitzinger 1843).
Diagnosis (genus): species of Glaucomastix are characterized by the absence of preanal spurs, presence of granules in the supraorbital semicircles, less than 40 femoral pores, first superciliary divided, absence of an opercular projection of skin in the anterodorsal mar- gin of ear-opening, a light vertebral stripe, and a bright bluish-green tail (see Arias et al., 2011b). Glaucomastix can be distinguished from Ameivula in having a light vertebral stripe, a bright bluish-green tail and divided first superciliary (Arias et al., 2011; Harvey et al., 2012).
|Etymology||Glaucomastix is a composite name derived from the Greek adjectives “glaukos”,meaning blue-green, and “mastix”, meaning whip. The name alludes to the bluish-green tail that characterizes this group of lizards.|
Named after the habitat of the species, coastal sand dunes (lat. littoralis). Not mentioned in REEDER et al. (2002) as littoralis but these authors discuss the position of ocellifer to some extent.
