Northern groove-toothed shrew mouse

The northern groove-toothed shrew mouse, Microhydromys richardsoni, is a species of rodent in the family Muridae. It belongs to the genus Microhydromys and carries the authority Tate and Archbold, 1941. It is found in West Papua, Indonesia, and in Papua New Guinea, on the island of New Guinea. The Global Biodiversity Information Facility record of the IUCN Red List lists it as Data Deficient, meaning the available information is too limited to judge how threatened it is. The sources consulted give no details about its habitat, diet, body size or behaviour, so this entry stays short and records only the facts those sources support.
