Bassaricyon lasius 


Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Carnivora Procyonidae

Scientific Name: Bassaricyon lasius
Species Authority: Harris, 1932
Common Name(s):
English Harris's Olingo
Taxonomic Notes: The number of species comprising the genus Bassaricyon is uncertain. Some taxonomists recognize five separate species of olingos (B. alleni, B. beddardi, B. gabbii, B. lasius, B. pauli; taken from taxonomy of Honacki et al. 1982) while others lump them into just two species: B. alleni and B. gabbii (Macdonald 1988, Eisenberg 1989). A third viewpoint considers that there is a single olingo species (Decker and Wozencraft 1991, Emmons 1990).

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Helgen, K., Timm, R. & Schipper, J.
Reviewer(s): Duckworth, J.W. & Belant, J. (Small Carnivore Red List Authority)
This species is listed as Data Deficient (DD) as it is only known from the type locality in Costa Rica and is considered to be DD due to ongoing taxonomic uncertainty. Without knowledge of the distribution, populations or habitat and threats to the species, it is not possible to assess it against the IUCN Red List Criteria. This species was previously listed as Endangered, however, further research is needed to resolve issues surrounding taxonomic uncertainly, after which this species must be reassessed.
Previously published Red List assessments:
1996 Endangered (EN)
1994 Indeterminate (I)

Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: Though presumed to occur in montane forests based on the type specimen, noting is know of the habitat and ecology of this species.
Systems: Terrestrial

Threats [top]

Major Threat(s): The areas surrounding the type locality faces a number of threats including human conversion of habitat for agriculture and settlement - however, the extent of these threats remains unclear until taxonomic uncertainty is clarified.
