Species Sommeromys macrorhinos Musser and Durden 2002

Discussion: Crunomys Division. Monotypic and represented only by the holotype. Morphology of skin, skull, dentition, and stomach described and contrasted with other murines, particularly the Sulawesian shrew rats ( Melasmothrix , Tateomys , and Echiothrix ) and Sulawesi and Philippine shrew mice ( Crunomys ) by Musser and Durden (2002). Certain derived cranial osteological and cephalic arterial complexes suggest affinity with Crunomys ; otherwise, Sommeromys has no close morphological or phylogenetic affinity with any other described Sulawesian endemic. It may be a highly specialized relict of a group that diverged early from the Miocene Progonomys like murine ancestral stock.
