Soricomorpha (from Greek "shrew-form") is a formerly used taxon within the class of mammals. In the past it formed a significant group within the former order Insectivora. However, Insectivora was shown to be polyphyletic and various new orders were split off from it, including Afrosoricida ( tenrecs, golden moles, otter shrews), Macroscelidea (elephant shrews), and Erinaceomorpha ( hedgehogs and gymnures), with the four remaining extant and recent families of Soricomorpha shown here then being treated as a separate order. Insectivora was left empty and disbanded. [1]

Subsequently, Soricomorpha itself was shown to be paraphyletic, because Soricidae shared a more recent common ancestor with Erinaceidae than with other soricomorphs. [3] The combination of Soricomorpha and Erinaceidae, referred to as order Eulipotyphla, has been shown to be monophyletic. [4]

Living members of the group range in size from the Etruscan shrew, at about 3.5 cm and 2 grams, to the Cuban solenodon, at about 32 cm and 1 kg.
