Other common names: Cameroon Highland Hybomys, Eisentraut’s Hybomys, Eisentraut’s Striped Mouse

Taxonomy. Hybomys badius Osgood, 1936,

south-west slope of Mt Cameroon, Cameroon.

Hybomys badius was previously considered to be a subspecies of H. univittatus. De-scribed form H. eisentrauti, from Lefo and Oku mountains in Cameroon, is currently considered a synonym. A recent molecular analysis showed that specimens collected close to the type locality of H. rufocanus are close to those of H. badius; the older

name rufocanus would prevail. Monotypic.

Distribution. SW Cameroon.
