|Scientific Name:||Abudefduf declivifrons (Gill, 1862)|
Euschistodus declivifrons Gill, 1862
|Taxonomic Notes:||This species has been considered a synonym of Abudefduf concolor, but a recent molecular study by Lessios et al. (1995) confirmed that it is a separate species. It is closely related to A. concolor and is easily confused in the field during visual surveys. The distributions of the two species overlap between El Salvador and Costa Rica, and a combination of morphological and genetic comparisons throughout the ranges of both species are needed to establish the full range of each.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Allen, G.R. & Robertson, R.|
|Reviewer(s):||Carpenter, K.E., Polidoro, B. & Livingstone, S.|
This species is widespread in the Eastern Pacific, and is common in many parts of its range. There are no major threats for this species, and no current indication of population decline. It is listed as Least Concern.
|Range Description:||This species is endemic to the Eastern Pacific, and is found from lower Baja California and the central Gulf of California to Costa Rica, including Revillagigedo Island.|

|Population:||This species is locally common in suitable microhabitat throughout its range.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This reef-associated species is found in shallow rocky reefs exposed to surge to depths of five m. It is also common in intertidal and shallow subtidal rocky habitats.|
|Major Threat(s):||There are no major threats known for this species.|
|Conservation Actions:||There are no known conservation measures for this species. However, this species' distribution falls partially into a number of Marine Protected Areas in the Eastern Pacific region (WDPA 2006).|
