The Micropygidae form a family of sea urchins within the Diadematoida order of echinoderms. The family contains two living species of the genus Micropyga and one, Kierechinus, known only from fossils.[1] Morphologically, they are quite flat and have short, sharp spines, which are close to each other. They occur in the Indian and Pacific Oceans.
