Callewaert's mouse

Callewaert's mouse (Mus callewaerti) is a species of rodent in the family Muridae. The Wikipedia article that serves as this entry's source says it is found in the highlands of Katanga in the Democratic Republic of the Congo, and that its natural habitat is dry savanna. The article is three short sentences long. It gives no body measurements, diet, lifespan, population figure or conservation category, and it does not say who the species is named for. Those details are left blank here rather than guessed, and the description is limited to the identity, family, range and habitat that the one source establishes.
