Etymology: Norfolkia: Named for the Norfolk Island ( In 1953 Henry W. Fowler named this new genus on a Collection of Fishes Made by Dr. Marshall Laird at Norfolk Island) (R.Bajol, pers.comm. 04/2016).; brachylepis: Named for the scales on the pectoral fin base (Latin 'brachium' for upper arm and 'lepis' for a scale of a fish) (R. Bajol, pers.comm. 04/16)..

Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 18 - 19; Μαλακές ραχιαίες ακτίνες (συνολικά) : 10 - 11; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 20 - 21. This species is distinguished by the following characters: D IV + XIV-XV + 10-11 (IV+XV+11); A II, 20-21 (21), spine length half of the rays; pectoral rays 16, dorsalmost 2-3 and ventral most 7 simple, remainder branched once; pelvic rays bound together by membrane for less than one-fourth of length of shorter ray; lateral line pored scales 21-24 (22), terminates between 2nd and 3rd dorsal fins; notched scales and 14-19 (16); total lateral scales 32-35 (34); dentary pores 5-6 + 1 + 5-6; orbital and nasal cirri palmate and about as large as pupil diameter; dorsal fin also with cirri at tips of spines; head 2.9-3.6 (3.3) in SL, eye 3.0-3.9 (3.3), maxilla 2.3-3.0 (2.6) and snout 3.3-4.9 (3.8) in head length (Ref. 88983).
Adults inhabit coral or rock, often under ledges, on clear lagoon and seaward reefs (Ref. 13227). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
