The hairy-eared dwarf lemur Allocebus trichotis , or hairy-eared mouse lemur , is one of the most scarcely known lemurs. It was originally named by Dr. However, in Petter-Rousseaux and Petter reassigned the lemur to its own genus and is the now only member of the genus Allocebus. Allocebus trichotis is thought to have been discovered as early as by Dr.
Hairy-eared dwarf lemurs, Allocebus trichotis , are unquestionably among the rarest of surviving lemurs, and presumably have never existed in high numbers. Allocebus trichotis had not been seen in over 20 years when, in March , it was rediscovered in the vicinity of the Mananara River in northeastern Madagascar, which is its exclusive habitat. Until its rediscovery, it was only known from five museum specimens.
It is found in the Afrotropics. It is a solitary invertivore. They are threatened with extinction and CITES prohibits international trade in specimens of these species except when the purpose of the import is not commercial, for instance for scientific research. In these exceptional cases, trade may take place provided it is authorized by the granting of both an import permit and an export permit or re-export certificate.
