Etymology: Stegastes: Greek, stegastos, -e, -on = covered (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
; marino associati a barriera corallina; non migratori; distribuzione batimetrica 0 - 2 m (Ref. 9710). Tropical; 12°S - 27°S
Western Indian Ocean: known only from Madagascar, Reunion, and Mauritius.
Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm SL maschio/sesso non determinato; (Ref. 510)
Spine dorsali (totale): 12 - 13; Raggi dorsali molli (totale): 15-17; Spine anali 2; Raggi anali molli: 12 - 14. Body color is blue-black with black scale outlines. The scales on the nape and the side of the head are frequently blue. The lips are whitish. There is a small black spot near lateral line origin. A broad white bar is sometimes present across the middle of the sides (possibly associated with courtship behavior).
Adults are found in the surge zone of inshore boulder areas (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).
