Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA CHIROPTERA PHYLLOSTOMIDAE

Scientific Name: Lichonycteris obscura
Species Authority: Thomas, 1895
Common Name(s):
English Dark Long-tongued Bat
Taxonomic Notes: Easily confused with other nectivorous bats. Includes degener.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Tavares, V. & Mantilla, H.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
Listed as Least Concern because it is widespread. The disjunct distribution of the species is unlikely to be declining at a rate which would qualify it for inclusion in a threat category. However, the separate southeast Brazilian population is threatened by deforestation of Atlantic Forests.

Geographic Range [top]

Range Description: This species occurs from Chiapas, Mexico, south through eastern Guatemala, southern Belize, Honduras, the Isthmus of Panama, through western Venezuela and Guianas, to northern Peru, Bolivia, and Amazonian Brazil (Reid, 1997; Eisenberg and Redford, 1999). Lowlands to 1,000 m (Reid, 1997). A disjunct population occurs in southestern Brazil. In Bolivia known up to 500 m (Aguirre pes comm), in Ecuador to 900 m and in Peru to 800 m.

Population [top]

Population: This is a naturally rare species throughout its range. Rare but widespread (Emmons and Feer, 1997).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Poorly known. Usually recorded in lowland evergreen forest and plantations (Reid, 1997). This bat visits flowers and probably feeds on nectar, pollen, and insects (Eisenberg and Redford 1999; Tschapka 2004). Known from lowland moist forest (Ochoa pers. comm.). In Bolivia occurs in montane forests (Aguirre pers. comm.).
Systems: Terrestrial

Threats [top]

Major Threat(s): In Bolivia considered vulnerable. Conversion of forests to pasture (deforestation). The disjunct population in southeast Brazil is threatened by deforestation.

Conservation Actions [top]

Conservation Actions: Conservation of forest. The species occurs in a number of protected areas throughout its range.
