Distribution and habitat. Loxopholis guianense is endemic to eastern Amazonia, with its western distribution delimited by the Essequibo and Trombetas rivers north of the Amazon River, and Xingu River south of it, occurring in Brazil, French Guiana, Suriname, and Guyana (Fig. 13). In Brazil, it is known from the states of Amapá, Pará, and Amazonas. Loxopholis guianense is terrestrial and diurnal, inhabits primary terra firme and flooded (varzea) forests, where it is found among the leaf litter, in shaded spots, mostly near creeks (Hoogmoed 1973; Gasc 1986; Hoogmoed & Ávila-Pires 1991; Ribeiro-Júnior et al. 2006; Ávila-Pires et al. 2010).
