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)
