Common names: Guatemalan palm-pit viper,[3] Guatemalan tree viper.[4]

Bothriechis bicolor is a venomous pit viper species found in southern Mexico, Guatemala and Honduras.[1] The specific name refers to the contrasting ventral and dorsal colors.[3] No subspecies are currently recognized.[5]


Adults are usually 60–70 centimetres (24–28 in) in length, but may reach 100 centimetres (39 in), and the body is relatively slender.[3]

The color pattern consists of a green or bluish green ground color. Usually this is without any pattern, but sometimes specimens from Mexico have black flecks and dots and/or blue blotches. The dorsum of the head is a uniform green without any postocular stripe. The interstitial skin is often blue, which can also be true for the borders of some scales. The belly has a somewhat lighter color, usually a uniform yellowish-green.[3]

Geographic range[edit]

Found along the Pacific versant from southeastern Chiapas in Mexico, east to south-central Guatemala. Also known from a few locations in Honduras in the southern part of the Sierra del Merendón and the Cerro Santa Bárbara. The type locality given is "Des forêts de Saint-Augustine, département de Solola (Guatémala), sur le versant occidental de la Cordillèra. 610 mètres d'altitude" [= Forests of St. [San] Augustín, on western slope of the Cordillera, Department of Sololá, Guatemala, 610 m]. Actually, San Augustín is on the southern slope of Volcán Atitlán.[2]


Prefers rain forests and cloud forests between 500 metres (1,600 ft) and 2,000 metres (6,600 ft) elevation.[2]

Conservation status[edit]

This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001).[1] Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend is stable. Year assessed: 2007.[1]
