The Ruwenzori shrew (Ruwenzorisorex suncoides) is a species of mammal in the Soricidae family. It is monotypic within the genus Ruwenzorisorex.
Listed as Vulnerable because its area of occupancy is less than 2,000 km² (montane streams within a specific forest type), its distribution is presumably severely fragmented, and there is continuing decline in the extent and quality of its forest habitat.
This species is endemic to the Albertine Rift, occurring in the Ruwenzori Mountains (both in Uganda and the Democratic Republic of the Congo), additional parts of Uganda, eastern Democratic Republic of the Congo, Burundi and Rwanda. It has an elevational range of 800 to 2,350 m asl. This species has been recorded from the Rwenzori Mountains National Park, Uganda, and might be present in additional protected areas. Additional studies are needed into the distribution, abundance, general ecology and threats to this little-known species.
Very few specimens of this species have ever been collected, and little is known about the species overall abundance.
This species is associated with damp and dense mossy vegetation in motane primary tropical moist forest. It appear to be a specialised semi-aquatic species that has been captured from shallow streams.
It has a relatively restricted range, within which it is presumably threatened to some degree by habitat loss resulting from logging operations and the general conversion of land to agricultural use.
