Amazon Coastal House Snake

distribution

Distribution. Known from Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela (Plt. 357 A). In Brazil, widespread in Amazonia and the northern part of the Atlantic Forest, with marginal records near its contact with the Caatinga, forming a disjunct distribution (Plt. 357 A). Recorded mostly at low elevations (Plt. 357 B). Maps and taxonomy in Bailey et al. (2005). Observed in the field in wet forest (Silveira et al., 2017), close to water (Cunha and Nascimento, 1993; McDiarmid and Donelly, 2005; Santana et al., 2008) and open areas (Guedes et al., 2014).

Thamnodynastes pallidus (Linnaeus 1758) Linnaeus 1758

Thamnodynastes pallidus (Linnaeus, 1758) . “Jararaquinha” (Figs. 19.6 and 31.4) Recorded in the states of Pernambuco, Alagoas, Sergipe, and Bahia. It occurs from highlands in Sergipe and Bahia (maximum 800 m elevation) to low altitudes in contact areas with the Atlantic Forest. It was redescribed and its distribution was restricted to the Amazon Forest region (Bailey et al. 2005). However, this species was found also in forested enclaves within the Caatinga region, and presents a disjunct range as mentioned by Franco and Ferreira (2002). It is a forested area species that can be found in relictual moist forests on highland, and bush and arboreal caatinga in contact areas next to the Atlantic Forest. It has terrestrial habits, is nocturnal and feeds on frogs (Bailey et al. 2005).
