Abstract: The Amazon tree boa Corallus hortulanus is known for featuring a wide variation in color pattern and design markings. Although there are studies on its polychromatism, none of them addresses the geographic variation in the color pattern of this species. The aim of this study was to describe the chromatic variation found in the populations of C. hortulanus from the southern Amazon Basin and its relationship with geographic distribution of the species. Analysis of both design markings and color patterns on 112 C… Show more

“…Henderson (1997) classified the color patterns of this species into different categories based on the presence of spots on the dorsolateral and cephalic dorsal regions of the body for three background color morphs (taupe, yellow and brown). Although some color patterns in this species tend to be more frequent in certain regions of the Amazon, and the selection of color morphs by environmental variations has been suggested without explicit hypothesis testing, the predictor variables for the occurrence of color morphs are still unknown (Duarte et al 2015).…”

“…The tree boa Corallus hortulana (Linnaeus, 1758) is a medium-sized booid with a maximum snout to vent length of 1787 mm (Henderson 2002). It is a primarily nocturnal and ACTA AMAZONICA arboreal snake species that is widely distributed throughout South America (Henderson et al 1995;Stafford and Henderson 1996;Henderson 1993Henderson , 1997Henderson , 2002Duarte et al 2015). The species inhabits mostly lowland areas, including: primary and secondary forest, seasonally flooded savannas, flooded forests, dry forests, and gallery forests associated with rivers, streams, and lagoons (Silva 1993;Stafford and Henderson 1996;Henderson 1993Henderson , 1997Henderson , 2002Martins and Oliveira 1998;Duellman 2005;Rivas et al 2022).…”

“…Amazonian populations of C. hortulana are highly polychromatic, displaying a range of colors and patterns (Stafford and Henderson 1996;Henderson 1993Henderson , 1997Henderson , 2002Duarte et al 2015). Polychromatism in snakes has been suggested to be associated with several environmental, geographical, behavioral, and genetic variables (Henderson 1997;Farallo and Forstner 2012;Pizzatto and Dubey 2012;Duarte et al 2015). In C. hortulana, the polychromatism has been described and categorized into character states or morphotypes [see Henderson (1997) and Duarte et al (2015) for more details].…”
