- Common names: Oaxacan dwarf boa.
Exiliboa is a monotypic genus[2] created for the non-venomous dwarf boa species, E. placata, which is endemic to southern Mexico. No subspecies are currently recognized.[3]
Description
E. placata is shiny black in color.[4]
Behavior
E. placata is fossorial.[4]
Geographic range
E. placata is found in the Mexican state of Oaxaca in the Sierra de Juárez and Sierra Mixe near Totontepec. The type locality given is "near latitude 17° 37' N. and longitude 96° 25' W., at an elevation of approximately 2300 meters [7,546 feet] on the headwaters of the Río Valle Nacional on the northern slopes of the Sierra de Juárez, in the State of Oaxaca, Mexico".[1]
Conservation status
The species E. placata is classified as Vulnerable (VU) on the IUCN Red List of Threatened Species with the following criteria: B1ab(iii) (v3.1, 2001).[5] A species is listed as such when the best available evidence indicates that the geographic range, in the form of extent of occurrence, is estimated to be less than 20,000 km² (7,772 sq mi), estimates indicate it to be severely fragmented or known to exist at no more than 10 locations, and a continuing decline has been observed, inferred or projected in the area, extent and/or quality of habitat. It is therefore considered to be facing a high risk of extinction in the wild. The population trend is down. Assessed in 2007.[6]
