The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.
Sommer's Sulawesi rat is a species of rodent in the family Muridae from Sulawesi. It is the only species in the monotypic genus Sommeromys and was described by Musser & Durden in 2002.
Tateomys is a genus of rodent from Sulawesi. Both species have been classified as vulnerable by IUCN. It includes the following species:
The shrewlike rats, genus Rhynchomys, also known as the tweezer-beaked rats are a group of unusual Old World rats found only on the island of Luzon in the Philippines. They look a great deal like shrews and are an example of convergent evolution. Shrewlike rats evolved to be vermivores and insectivores feeding on soft-bodied invertebrates associated with leaf litter.
Archboldomys, the shrew-mice, are a genus of rodents in the family Muridae. They are carnivores that feed on invertebrates much like shrews do. An apparently smaller relatives of the true shrew-rats Chrotomys and Rhynchomys, Archboldomys are somewhat convergent to the more distantly related Crunomys.
The Celebes shrew-rat is a species of rodent in the family Muridae. It is found only in Sulawesi, Indonesia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
The Northern Luzon shrew-rat is a species of rodent in the family Muridae. It is found only in the Philippines. Its natural habitat is subtropical or tropical dry forest. It is threatened by habitat loss.
The Mindanao shrew-rat is a species of rodent in the family Muridae. It is found only in the Philippines.
The Sulawesian shrew rat is a species of rodent in the family Muridae. It is the only species in the genus Melasmothrix. It is found only in central Sulawesi, Indonesia, and is known from the localities of Rano Rano and Mount Nokilalaki.
The Isarog shrew-rat or Mount Isarog shrew-rat is a species of rodent in the family Muridae. It is found only in the Philippines.
The Christmas Island shrew, also known as the Christmas Island musk-shrew is an extremely rare or possibly extinct shrew from Christmas Island. It was variously placed as subspecies of the Asian gray shrew or the Southeast Asian shrew, but morphological differences and the large distance between the species indicate that it is an entirely distinct species.
A shrew rat or shrew-rat is not a true rat but a rodent that resembles a shrew in physical form and, presumably, lifestyle. There are twelve known species distributed across seven known genera, all from island southeast Asia, specifically the Indonesian island of Sulawesi and several islands of the Philippines:
The Sierra Madre shrew mouse is a species of mammal from the Philippines.
Guy Graham Musser was an American zoologist. His main research was in the field of the rodent subfamily Murinae, in which he has described many new species.
Soricomys, the shrew-mice, are a genus of rodents in the family Muridae. They are carnivores that feed on invertebrates much like shrews do. An apparently smaller relatives of the true shrew-rats Chrotomys and Rhynchomys, Soricomys are somewhat convergent to the more distantly related Crunomys.
The Sulawesi montane rain forests is a tropical moist forest ecoregion in Indonesia. It includes the highlands of Sulawesi.
