Brachytarsomys mahajambaensis Mein et al. 2010

Mahajamba Bay antsangy1



Taxonomy & Nomenclature

Brachytarsomys mahajambaensis was described by (Mein et al. 2010) and is the smallest known member of the genus thus far discovered.


The common name for this species was proposed by Peter Maas:1

"The specific name, mahajambaensis, refers to Mahajamba Bay and the other members of the genus Brachytarsomys are called Antsangy (White-tailed Antsangy and Hairy-tailed Antsangy). So it seemed logical to name this species the Mahajamba Bay Antsangy."
