Hyorhinomys stuempkei

Hyorhinomys stuempkei is a recently discovered species of rodent in the family Muridae, endemic to Sulawesi, Indonesia. Described as a "hog-nosed shrew rat", the discoverers proposed "Sulawesi snouter" as a common name for it. The word "snouter" references the fictional text, The Snouters: Form and Life of the Rhinogrades by the German zoologist Gerolf Steiner. Steiner wrote this text as a fictional naturalist, Harald Stümpke, and the specific epithet of H. stuempkei pays homage to this fictional individual.

The species has particularly long incisors. Unusually, it lacks the coronoid process jaw muscle attachment point, presumably because its diet of earthworms and beetle larvae does not require forceful chewing.

Its morphological distinctions from other shrew rats, along with phylogenetic analysis, led to it being placed in the new genus Hyorhinomys as the only species.
