Distribution and habitat
Stegastes leucorus is native to the tropical eastern central Pacific Ocean. Its range extends from Mexico and Baja California to the Revillagigedo Islands and Guadalupe Island. It inhabits rocky and coral inshore reefs where it is found at depths down to about 15 m (49 ft).
Status
This fish is common in parts of the Revillagigedo Islands but uncommon on the mainland coast. It is estimated that 90% of its total population is confined to a single area of the Revillagigedo Islands, a total occupancy of less than 2,000 km2 (772 sq mi). Because of its shallow water habitat and limited range, the IUCN has listed it as "Vulnerable" in view of the fact that El Niño events periodically affect this area.
