Leimacomys buettneri Matschie, 1893:109

Groove-toothed forest mouse, Yefuli



Taxonomy & Nomenclature

Synonym/s: Leimacomys buttneri Matschie, 1893:109 (orthographic error); Leimacomys büttneri Matschie, 1893:109


Conservation Status


Last record: 1890 (Fisher & Blomberg, 2012; Lee et al., 2017); 1893 (Martin et al., 2023)

IUCN RedList status: Data Deficient


Only known from two specimens collected in 1890 (van der Straeten & Schlitter, 2008). Two surveys during the 1960's didn't uncover the species (Lidicker, 1989:35). Likewise, two surveys, one in 1994 and the other in 1999 or 2000, failed to rediscover this species (Decher et. al. 2000). It's historical distribution may have included Ghana as the type locality is close to the Togolese/Ghanaian border (van der Straeten & Schlitter, 2008).



Bismarckburg, Togo (central)


Biology & Ecology




Only known from two specimens collected in 1890 (van der Straeten & Schlitter, 2008).

Type locality: Bismarckburg, central Togo
