Distribution and habitat. Tretioscincus agilis  is endemic to eastern Amazonia  , with its western distribution delimited by the Negro River north of the Amazon, and the Xingu River south of it, occurring in Brazil, French Guiana, and Suriname ( Fig. 18View FIGURE 18). In Brazil, it is known from the states of Amapá, Pará, Amazonas, Roraima, and Mato Grosso. Tretioscincus agilis  is semi-arboreal and diurnal, inhabits primary terra firme forest, venturing into open vegetation in the enclaves of saxicolous vegetation (campos rupestres) in Carajás, southern Pará. It is found at several heights on tree stumps (often black and very much decayed), buttresses or trunks, lianas, and palm stems, as well as among leaf litter; often in sunny patches, as clearings and forest edges (Hoogmoed 1973; Nascimento et al. 1987; Hoogmoed & Ávila-Pires 1991; Martins 1991b; Ávila-Pires 1995; Gardner et al. 2006; Ribeiro-Júnior et al. 2006; Vitt et al. 2008; Ávila-Pires et al. 2010).
