Morphological characters

This species is only known from the slopes of Mt Oku and is characterized by its larger size ( Table 6) compared to other Hylomyscus species.We collected seven specimens of this rare species during our study. H. grandis belongs to the aeta complex, which is characterized by a broad wedge-shaped interorbital area, well marked supraorbital crests, relatively large molars and a less fragile skull than other species. Our specimens clearly belong to this complex of species. Molecular sequencing confirms his distinctiveness to other species of the aeta complex (Missoup, pers. comm.). Their skulls, as well as their external measurements, are similar to those of specimens of H. grandis already described from Mt Oku.
