Distribution and habitat. Plica umbra ochrocollaris is endemic to Amazonia, with a predominantly southern distribution (southern Amazon River, in western side of Negro River), but also in both sides of the upper Negro River, in the upper tributaries of Orinoco basin, and in both sides of the lower Amazon, occurring in Brazil, Venezuela, Colombia, Ecuador, Peru, and Bolivia (Fig. 17). In Brazil it is known from the states of Amapá, Pará, Maranhão, Tocantins, Amazonas, Acre, Rondônia, and Mato Grosso. Plica umbra ochrocollaris is arboreal and diurnal, inhabits primary and secondary terra firme and varzea forests, and gallery forests, where it is found on trunks of small to moderate-sized trees, about 2.4 meters above ground (observations in literature varying between 0.3 and up to 6 meters high), and rarely but also on fallen tree trunks, palm stems, bamboo twigs, lianas, and on the ground (Cunha 1961; Duellman 1978; Cunha et al. 1985; Dixon & Soini 1986; Nascimento et al. 1988; Ávila-Pires 1995; Vitt & Zani 1996c; Vitt et al. 1997; Harvey & Gutberlet 1998; Schlüter et al. 2004; Whitworth & Beirne 2011).
