Büttner's african forest mouse, Groove-toothed forest mouse
The Togo mouse (Leimacomys buettneri ), also known as Büttner's African forest mouse or the groove-toothed forest mouse, is a unique muroid rodent known from only two specimens taken from near the type locality of Bismarckburg, near Yege, Togo, in 1890. Its genus is monotypic.
The Togo mouse is considered to be either critically endangered or extinct depending on the authority. Schlitter classified it as extinct, because subsequent surveys to the area failed to recover it. Grubb et al. (1998) noted these surveys inadequately sampled appropriate habitat in Togo and neighboring Ghana, and they were reluctant to declare the species extinct. Musser and Carleton also emphasized the insectivorous muroids as a group have proven difficult to capture, and intense surveys of high-elevation forests in this region are required to determine if it still persists.
The IUCN currently describes the Togo mouse as "data deficient".
