Distribution and habitat. Pseudogonatodes guianensis is endemic to, and widespread in large part of Amazonia, but apparently rare or absent in the Madeira, Xingu and Tocantins river basins (Fig. 10). It occurs in Brazil, Guyana, Venezuela, Colombia, Ecuador, and Peru (Fig. 10). Hoogmoed (1973) and Gasc (1976) also reported it from Suriname and French Guiana, respectively. In Brazil it is known from the states of Amapá, Pará, Amazonas, Acre, and Mato Grosso. Pseudogonatodes guianensis is terrestrial and diurnal, inhabits primary and secondary terra firme forests, and swampy areas, where it is found among the leaf litter, at the base of palms and trees, and under fallen tree trunks (Gasc 1976; 1986; Duellman 1978; Hoogmoed & Ávila-Pires 1989; Duellman & Mendelson 1995; Ávila-Pires 1995; Schlüter et al. 2004; Vitt et al. 2005; Ávila-Pires et al. 2010; Whitworth & Beirne 2011). Dixon & Soini (1975, 1986) found individuals associated with patches of sunlight inside the forest, and Duellman & Mendelson (1995) found it in disturbed areas. However, Hoogmoed (1973) and Gasc (1981, 1990) observed it in association with the most humid places in the forest, and Vitt et al. (2008) noted its absence when the canopy is opened and the sunlight penetrates to the forest floor.
