Bothrops insularis

Bothrops insularis is a chordate, or more specifically a reptile, in the Viperidae family.

Bothrops insularis is commonly known (its common name) as the Golden Lancehead or the Queimada Island Bothrops in English.

Bothrops insularis is classified as critically endangered by the IUCN Red List of Threatened Species, the world's most comprehensive inventory of the global conservation status of plant and animal species maintained by the International Union for Conservation of Nature and Natural Resources. Bothrops insularis's population trend was stable at last assessment meaning its population is neither increasing or decreasing significantly in the wild.




Species Authority: The species authority, or the name(s) of scientist(s) or person(s) who first described Bothrops insularis is (Amaral, 1921) (IUCN Red List).

Country Distribution: Bothrops insularis is found in the following countries:
    Brazil (So Paulo)
(IUCN Red List).

Biome(s)/Ecosystem(s): IUCN lists the following as biomes for Bothrops insularis: Terrestrial (IUCN Red List).

Major Habitat(s): 1.6 Forest - Subtropical/Tropical Moist (IUCN Red List).

Range: Bothrops insularis is known only from Queimada Grande Island, off the coast of So Paulo, southeastern Brazil (Campbell and Lamar 1989). (IUCN Red List).

CONSERVATION STATUS

Red List Category & Criteria: Bothrops insularis is listed as CR B1ab(iii)+2ab(iii)    ver 3.1 (2001) (IUCN Red List).

Year Assessed: Bothrops insularis's status was assessed in 2004 (IUCN Red List).

Assessor: Bothrops insularis's Red List status was evaluated by Marques, O.A.V., Martins, M. & Sazima, I. (IUCN Red List).

Red List Evaluator: The Red List Evaluator for Bothrops insularis is listed by IUCN as Hilton-Taylor, C. & Amori, G. (Rodent Red List Authority) (IUCN Red List).

Red List Rational / Justification : Bothrops insularis is listed by IUCN for the following: Bothrops insularis is known only from one location: a small island off southeastern Brazil (total area 43 ha). The species' highly restricted range and continuing decline in habitat quality, as a result of removal of vegetation by people from the Brazilian Navy who keep the lighthouse, qualify it for the Critically Endangered category. (IUCN Red List).

Threats: 1.7 (Wikipedia).

Red List History: Bothrops insularis was listed on the IUCN Red List of Threatened Species in 1986 (IUCN Red List).
