Exiliboa is a monotypic genus [2] created for the non-venomous dwarf boa species Exiliboa placata, which is endemic to southern Mexico. No subspecies are currently recognized. [3]
E. placata is shiny black in color. [4]
E. placata is fossorial. [4]
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]
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]
The Tropidophiidae, common name dwarf boas or thunder snakes, are a family of nonvenomous snakes found from Mexico and the West Indies south to southeastern Brazil. These are small to medium-sized fossorial snakes, some with beautiful and striking color patterns. Currently, two living genera, containing 34 species, are recognized. Two other genera were once considered to be tropidophiids but are now known to be more closely related to the boids, and are classified in the subfamily Ungaliophiinae. There are a relatively large number of fossil snakes that have been described as tropidophiids, but which of these are more closely related to Tropidophis and Trachyboa and which are more closely related to Ungaliophis and Exiliboa is unknown.
