Microcerberidae

The Microcerberidae are a family of isopod crustaceans. They are less than 2 mm long, and live interstitially in shallow marine or freshwater sand habitats.

Marine microcerberids comprise the main part species diversity, but are very alike. As a group, they have very broad distribution: Freshwater taxa are less abundant in species number (only 12 species), but are more morphologically diverse and include seven or eight genera. They have these distributions:
 * the majority of Coxicerberus: Americas, southern coasts of Europe, Africa, warm waters of Asia, New Zealand
 * "Microcerberus" monodi: Angola
 * Afrocerberus and Protocerberus: central and southern Africa
 * Bulgarocerberus: Bulgaria
 * Isoyvesia: Cuba
 * Mexicerberus: Mexico
 * Microcerberus: South Carolina, Romania, Bulgaria and Macedonia
 * "Microcerberus" remyi: Morocco
 * Coxicerberus ruffoi: northern Italy
