It is native to the tropical eastern Pacific Ocean, its range extends from Mexico, Baja California and the Gulf of California southwards to the Galapagos Islands and mainland Ecuador. It is found on rocky inshore reefs at depths ranging from 1to.[1]
Stegastes flavilatus has a wide distribution and is common in many parts of its range, particularly the mainland coast, but less common around the Revillagigedo Islands, the Galapagos and Cocos Islands, and its populations appear to be stable. No particular threats to this species have been identified and the IUCN rates it as being of "Least Concern".
