Mittendorf's Lemniscomys is a striped mouse recorded around Mount Oku in Cameroon. Specimens have a broad black dorsal stripe with rows of red spots on either side.
The described specimens have a broad black stripe down the back, flanked by several discontinuous rows of red spots. Their skulls and feet are also described as relatively short.
A record of this species came from owl pellets collected in a cave near Lake Oku. This documents predation, not the species' main diet.
