Overview

Distribution

Range Description

This species occurs in the area of Volcan and Ujarras de Buenas Aires, Costa Rica, and Boquete, Panama (Dwyer and Van Den Bush, in press). Records of Porthidium lansbergi from Chiriquí and the "Cordillère de Veraguas", both in Panama, may also refer to this species (Campbell and Lamar 2004). The elevational range extends from 418 to 1,000 m asl (Sasa et al. 2010), although other sources give a lower elevation of 400 m asl (Solorzano, Campell and Lamar 2004).

Habitat and Ecology

Habitat and Ecology
The preferred habitat for this species is unknown; Campbell and Lamar (2004) describe its broad habitat affinities as "Tropical moist forest", however they do not elaborate on this and provide detailed information only on its occurrence in secondary growth and mesic savanna grassland. It has been found in pineapple plantations and heavily disturbed habitats in former mesic forest (Sasa et al. 2010). The holotype was collected in a disturbed area of secondary growth, in which only remnants of the original forest remained (Campbell and Lamar 2004). It is a terrestrial and apparently nocturnal snake (Solorzano 2004), but nothing else is known of its biology although Solorzano describes it as viviparous.

Justification
This species is classified as Data Deficient due a lack of information about its natural history, habitat preferences, distribution, and population status; while it appears at least somewhat able to tolerate disturbed habitats, it is rare and has an apparently limited range. Additionally, clarification is needed to resolve seemingly inconsistent descriptions of its habitat preferences, making determining its ecological requirements impossible..
