The Lipotyphla, or 'insectivores', are a group of small mammals including shrews, hedgehogs, moles and others. It is currently uncertain whether the Afrosoricida (tenrecs and golden moles) should be classified with the Lipotyphla: molecular analyses of modern taxa have strongly indicated they are instead allied to other Africa-derived mammals in a group called the Afrotheria. However, morphological analyses conducted to date such as Wible et al. (2007) persist in recovering a monophyletic Lipotyphla, even if they do recover a clade containing the remaining Afrotheria. Assignation of many fossil taxa is even more problematic. Butler (1988) regarded the placement of the Eocene Dormaaliidae and Palaeocene-Eocene Micropternodontidae as lipotyphlans as doubtful, but they are listed here as basal forms in the absence of suggested alternative placements.

Among the more divergent established lipotyphlans are the Solenodontidae (solenodons), moderately large (about a foot long excluding the tail) insectivores found only on the islands of Cuba and Hispaniola. Until recently, the Caribbean islands were also home to the now-extinct species of Nesophontes.

Characters (from Butler 1988): Mobile snout, with enlarged olfactory organs, enlarged infraorbital canal, and reduced eyes. Palatine displaced from lacrimal by maxillar wing and confined to orbital floor; jugal reduced or absent, lower border of orbit formed from maxilla. Pubic symphysis reduced or lost. Caecum lost.
