A reference list of chromosome numbers of about 110 species in the order insectivora is presented. Cytotaxonomic data are known for six families: Solenodontidae, Tenrecidae (incl. Potamogalidae), Erinaceidae, Soricidae, Talpidae and Macroscelididae (only the Chrysochloridae remain unstudied). The list provides, wherever possible, the diploid chromosome number(s), Nombre Fondamental, and references; sometimes information on geography, synonymy, as well as short comments are added.
