Geographic range: It is found in Peru, northern Venezuela, Colombia in the Guainía and Trinidad and Tobago.

 The body is elongate, and strongly laterally compressed. The tail is long, as the common name implies. The dorsum is olive to light brown. There is a narrow whitish, black-edged, vertebral stripe. The upper labials and the ventrum are yellowish.

Adults may attain a total length of 136 cm, with a tail 56 cm long.
