Oryzorictinae is a subfamily of tenrecs endemic to the island of Madagascar. It is the largest of three tenrec subfamilies. Oryzorictinae is thought to have split from the lineage of its closest relative, Geogale, about 30 million years (Ma) ago. The deepest phylogenetic split within the subfamily, that between Oryzorictes and a clade composed of Microgale plus Nesogale, is thought to have occurred about 28 Ma ago. In turn, Microgale and Nesogale are thought to have diverged about 19 Ma ago.
