Gymnophthalmus  sp.

Taxonomic remarks. Gymnophthalmus  sp. was previously cited by Vanzolini & Carvalho (1991) and Carvalho (1997) as a new species from the underwoodi  group, mainly by having a reddish tail (in contrast to other known Brazilian species that have a blue/gray tail). Ávila-Pires (1995) shows a drawing of a specimen from Alter do Chão, Pará, Brazil ( MPEG 16257View Materials). Ávila-Pires et al. (2010) comment on its distinction from Gymnophthalmus vanzoi  on basis of a specimen from the central part (savannah area) of Ecological Station Grão-Pará, in northern of Pará, Brazil  .

Distribution and habitat. Gymnophthalmus  sp. is endemic to eastern Brazilian Amazonia  , where it occurs in the states of Amapá, Pará, and Roraima, in some relictual open vegetation enclaves north of the Amazon River, and south of it in the surroundings of Santarém and Belterra municipalities, Pará ( Fig. 9View FIGURE 9). Gymnophthalmus  sp. is sexually dimorphic, terrestrial, and diurnal, inhabits open vegetation enclaves, river beaches, and rocky slabs, where it is found among the leaf litter, on sandy exposed soil, and under rocks (Ávila-Pires 1995; Mesquita et al. 2006a; Ávila-Pires et al. 2010).
