More Info


Seal Rocks to Montague Island, New South Wales: also the Lord Howe Province and Norfolk Island in the Tasman Sea. Elsewhere the species occurs in the south-west Pacific: New Caledonia and New Zealand. This is one of the most common damselfishes outside the lagoon at Lord Howe Island. The habitat largely comprises of rocky canyons, ledges and boulders covered with algae.


Dorsal fin XIII, 13-15; Anal fin II, 15-16; Pectoral fin 16-18; Branched caudal rays 13; Gill rakers 20-23; Lateral line, tubed scales 16-18; Vertical scale rows from upper edge of gill opening to base of caudal fin 28; Horizontal scale rows from base of dorsal fin to terminal lateral line scale (exclusive of dorsal base sheath scales) 1.5; Scales from lateral line to anal fin origin 9; Predorsal scales ~ 18-20, extending to level of nostrils.
Body elongate, laterally compressed,  greatest depth: 2.3-2.5 in SL. Horizontal scale rows  between middle of lateral line and dorsal fin base 1.5; predorsal scales reaching  level of nostrils; suborbital and inferior limb of preopercle scaled; teeth uniserial, dorsal-fin outline uniform without incisions between spines.
Dorsal-fin origin at level of second tubed lateral line scale; posterior dorsal and anal rays elongate; caudal fin forked, lobes filamentous.


The specific name notialis is from the Greek notos (= southern), in reference to the geographical distribution of this species. It is the most southerly occurring species of Glyphidodontops and a common inhabitant of Lord Howe Island, the world's southernmost coral reef.
