Bothriopsis bilineata bilineata (Wied, 1821) (Serpentes: Viperidae): new records in the states of Amazonas, Mato Grosso and Rondônia, northern Brazil

Abstract

Although widely distributed in the Brazilian Amazonia, there are few published records of Bothriopsis bilineata in this region, with large gaps between them. This scarcity of reports of B. bilineata in nature may be caused by its arboreal habits, cryptic color, and a possible low density in many areas. Here we provide new registers of the subspecies B. b. bilineata, improving the knowledge of its distribution.

“…Bothrops bilineatus (Wied-Neuwied, 1821) -A small to moderate sized arboreal species (average SVL = 495 mm; N = 5), with nocturnal activity (Marques et al 2019). This species occurs in the Atlantic Forest and Amazon Forest (Bernarde et al 2011. In PEC occurs only in Alagoas state (Fig.…”

Snakebites in the Brazilian Amazon: Current Knowledge and Perspectives

“…Popularly known as green pit viper or parrot's beak jararaca, Bothrops bilineatus stands out for being relatively abundant in some regions and to present arboreal habits, which contributes to their bite that reaches the upper regions of the body of the victim. Two subspecies of the green pit viper are present in the Amazon: B. b. bilineatus is present in the states of Amazonas, Roraima, Amapá, Pará, south of Rondônia, and northern Mato Grosso; B. b. smaragdinus occurs in the states of Acre, Amazonas (Purus River basin), and Rondônia (northern state) (Bernarde et al 2011a). Adult specimens are between 70 cm and 1 m and, same as the juveniles, have arboreal habits.…”

New Distributional Records of the Bothrops Bilineatus Bilineatus (Wied 1825) (Serpentes:Viperidae) in Low Xingu River, Pará, Brazil

“…Two subspecies are currently recognized: B. b. Bilineatus found in Venezuela, Guyana, Suriname, French Guiana and Brazil; and B. b. smaragdina Hoge 1966, with records in the Amazon rainforest of Bolivia, Peru, Ecuador, Colombia, Venezuela and Brazil [1]. Bothrops b. bilineatus is found in the Brazilian states of Amazonas, Mato Grosso, Rondônia, Pará, Amapá, Maranhão, Bahia and Rio de Janeiro [2,1], with the type locality the city of Marabá River Peruhype, Bahia. Despite the records in several Brazilian states, the encounter with this species is very rare.…”

“…Campbell and Lamar [5] recognize that, due to its arboreal habit pattern of cryptic coloration and low population density in their occurrence areas, they are species of hard to record. Bernarde et al [2] suggest new trigger points for the states of Amapá, Amazonas, Rondonia and Mato Grosso. In this note, we add new information on the geographical distribution of B. bilineatus (Figure 1), record for the Brazilian state of Pará, on the right bank of the lower Xingu River.…”
