----------------------------
Description
Dorsal spines (total): 14; Dorsal soft rays (total): 13-14 (usually: 14); Anal spines: 2; Anal soft rays: 13-14; Pectoral fin rays: 18; Lateral line scales: 18-19; Gill rakers: 22-23; Body depth: 1.9-2.1 in SL. Margins of preopercle and suborbital smooth. Suborbital scaleless, teeth biserial. Max. length: 15.0 cm TL. Depth range: 2 - 30 m.
Color
Juveniles yellow-orange with a narrow blue band from snout to and surronding a black sport below middle of dorsal fin.
Adults brown with darker scale margins.
Etymology
Neoglyphidodon: from Greek, para = the side of + from Greek, glyphis = carved + from Greek, odous = teeth.
polyacanthus: from Ancient Greek, polús = many, much + from ancient Greek, ákanthos = thorn, spine. Referring to 14 dorsal-fin spines, exceeding the maximum (13) Ogilby knew about among its presumed congeners in Glyphisodon (=Abudefduf).

Original description: Glyphidodon polyacanthus Ogilby, 1889 - Type locality: Lord Howe Island (Australia) located in the Tasman Sea between Australia and New Zealand.
Distribution
Southwestern Pacific: Capricorn Group (southern Great Barrier Reef, Queensland, Australia), Lord Howe Island and Norfolk Island (Australia), New Caledonia.
Biology
Adults occur outside the lagoon, usually in deeper surge channels on the leeward side of reefs in the Capricorn Group, Queensland, Australia. Ubiquitous at Lord Howe Island. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.
Similar species
Chrysiptera brownriggii (Bennett, 1828) - Reported from Indian Ocean: South Africa, East Africa, Socotra, Seychelles, Comoros, Madagascar and Mascarenes east to western Indonesia.
