Etymology: rubrimacula: From the Latin ruber, red, and macula, spot, in reference to the conspicuous red spot at the midbase of the caudal fin. More on authors: Randall & Kulbicki.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 33 m (Ref. 33415). Tropical; 22°N - 28°S, 120°E - 178°E
Western Central Pacific: Ryukyu Islands south to Australia; Indonesia (Ref. 90102) east to Fiji Islands (Ref. 56673).
Length at first maturity / Size / Weight / Age
Maturity: Lm 3.5  range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 33415); max. reported age: 4 years (Ref. 56673)
soft rays: 8;
Vertebrae: 24. Predorsal scales 4; preopercular edge serrate; preopercular ridge smooth to slightly crenulate; body depth 2.85-3.05 in SL; silvery blue-gray with 6 orange to orange-yellow stripes on head and body, those on body narrower than blue-gray interspaces; third orange-yellow stripe from dorsal edge of eye ending below space between dorsal fins; midlateral orange-yellow stripe ending in a red spot at base of caudal fin (Ref. 33415).
Inhabit coral reef (Ref. 75154). Form small aggregations (Ref. 33415). Distinguished from A. cyanosoma by the presence of a single red spot at the midbase of the caudal fin, a higher number of gill rakers, and apparently a smaller maximum size (Ref. 33415).
Mouthbrooders (Ref. 240). Distinct pairing during courtship and spawning (Ref. 205).
