Issue
The Ascension I. population differs from the St. Helena I. population in having a bright spot at the rear end of the base of the dorsal fin. No genetic differences were found between the two populations that seem closest to the population from Brazil (Rocha et al., 2008).

Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 12; Mjukstrålar i ryggfenan (totalt) : 12 - 13; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 11 - 13. A prominent black spot at the pectoral-fin base, and a white spot just behind the posterior base of the soft dorsal fin (Ref. 7247). Grayish brown on back, shading to silvery gray on sides; dorsal fin broadly edged with bright yellow; upper and lower edges of caudal fin narrowly yellow with a submarginal dark band (Ref. 13442).
Adults generally occur in steep slopes and patch reefs. Diurnal species (Ref. 9626), they most commonly form moderate-sized feeding-schools over reef tops, rising above the bottom to feed on plankton, mainly copepods. Often seen with Chromis cyanea (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Rarely marketed (Ref. 3139).
