Overview

Distribution

Range Description

This species is found at low and moderate elevations of the Atlantic drainage from northwestern Chiapas (and possibly southern Tabasco and eastern Veracruz), Mexico, eastward through northern Guatemala and the Caribbean lowlands of Central America to Panama and northern Colombia to Ecuador. It occurs locally on Pacific drainages of Costa Rica and Panama, and thence southward on the Pacific Coast of Ecuador. Its elevational range throughout most of its range extends from near sea level up to about 900 m asl; in Colombia there is a questionable record at 1,880 m asl.

Description

Adults are usually less than 40 centimetres (16 in) in total length, and rarely more than 60 centimetres (24 in). Females are considerably larger than males. Moderately stout and terrestrial.[2]

Geographic range

Found in southern Mexico southward through Central America to western Colombia and northwestern Ecuador in South America. Inhabits the Atlantic lowlands from Mexico (Tabasco and Chiapas) through Belize, Guatemala, Honduras, Nicaragua and Costa Rica to eastern Panama and northwestern Colombia. In the Pacific lowlands, it occurs in southwestern Costa Rica, central and eastern Panama, continuing on to northwestern Ecuador. It is found in mesic lowland broadleaf or rainforest from sea level to elevation of about 900 metres (3,000 ft). The type locality given is "Pansos [Panzós], sur les bords du Polochic [Alta Verapaz] (Guatémala)."[1]

Conservation status

This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001).[5] 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.[6]
