Bothrops bilineatus (Wied-Neuwied, 1821)

Material examined. Field observation; (13°25′38″S, 069° 36′42″W), 22.IX.2013.

Identification. A small pitviper, SVL maximum 365– 840 mm in males and 555 mm in females. It can be identified by dorsal scales uniformly keeled but not tuberculated; 27–35 scale rows at mid-body; single anal plate. Dorsum pale green, with scattered black spots. Venter cream to white with a broken pale yellow paraventral stripe. This snake is arboreal with a prehensile tail. There are no similar pitviper species nearby. Some green colubrids such as Philodryas viridissimus , Liophis typhlus and the boid Corallus batessi could be confused, but they differ by lacking loreal pits and having labial pits respectively ( Roze 1966, Duellman 1978, 2005, Dixon and Soini 1986, Pérez-Santos and Moreno 1988, Harvey et al. 2005).

Distribution. Bothrops bilineatus is widely distributed in Amazonia in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname and Venezuela ( Harvey et al. 2005, Uetz and Hošek 2019).

Remarks. The individual was found dead in an advanced stage of decomposition, so it was not collected.
