Red List Criteria
This species has a highly restricted distribution with the entirety of its population confined to reef habitat in the Clipperton Atoll,with an area of occupancy estimated to be less than <10 km2. In the Eastern Tropical Pacific, severe localized fish species declines have occurred after strong ENSO events that result in shallow waters that are too warm and nutrient poor for extended periods of time (Grove 1985, Edgar et al. 2009). The frequency and duration of ENSO events in this region of the Eastern Tropical Pacific (e.g., the up-welling zone off the coast of Peru, Ecuador, Colombia, Panama and the offshore islands) appears to be increasing (Glynn and Ault 2000, Soto 2001, Chen et al. 2004). Given this species restricted distribution, oceanographic environmental changes, such as those associated with future ENSO events, may have detrimental effects on the survival of this species. However, this species is found in deeper waters and declines for this species may not be as severe as for other more shallow-water species.
There do not appear to be conservation measures in place for this species. The species does not appear to have been recorded from any marine protected areas. This species should be carefully monitored, given its restricted range and reef-restricted habitat.
