Myosoricinae is a subfamily of small mammals in the shrew family Soricidae, which in turn is part of the order Eulipotyphla. A member of this family is called a myosoricine, or an African shrew. Myosoricinae is one of three subfamilies in Soricidae, along with the white-toothed shrews of Crocidurinae and the red-toothed shrews of Soricinae. They are found in central and southern Africa, primarily in forests, and also in shrublands, grasslands, and wetlands. They range in size from the lesser Congo shrew, at 5 cm (2 in) plus a 1 cm (0.4 in) tail, to various members of the Myosorex and Surdisorex genera, at 11 cm (4 in) plus a 7 cm (3 in) tail. Myosoricines primarily eat insects and other invertebrates, as well as small birds and mammals. No myosoricines have population estimates, but 7 species are categorized as endangered species: the Geata mouse shrew, Kihaule's mouse shrew, long-tailed forest shrew, montane mouse shrew, Nyika burrowing shrew, Rumpi mouse shrew, and thin mouse shrew. Additionally, the Phillips' Congo shrew and Eisentraut's mouse shrew are categorized as critically endangered.
The 25 extant species of Myosoricinae are divided into three genera; 19 of them are in Myosorex and 3 each are in Congosorex and Surdisorex. A few extinct prehistoric Myosoricinae species have been discovered, though due to ongoing research and discoveries the exact number and categorization is not fixed. [1]

Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the myosoricine's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted.
The subfamily Myosoricinae consists of three genera: Myosorex , containing 19 species, and Congosorex and Surdisorex with three species each.

The following classification is based on the taxonomy described by the reference work Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis, as supported by both the IUCN and the American Society of Mammalogists. [2]
