Justification:
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.

History:

2000	–	Critically Endangered
1996	–	Critically Endangered
1994	–	Indeterminate (Groombridge 1994)
1990	–	Indeterminate (IUCN 1990)
1988	–	Rare (IUCN Conservation Monitoring Centre 1988)
1986	–	Insufficiently Known (IUCN Conservation Monitoring Centre 1986)
