Etymology: Rabaulichthys: Perhaps from Rabaul, the capital of Papua New Guinea + Greek, ichthys = fish.
Eponymy: Cadel Squire collected most of the type series. With his brother Lyle (below), he runs ‘Cairns Marine’, an Australian company exporting marine fauna. (Ref. 128868), visit book page.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 10; Raggi dorsali molli (totale) : 16; Spine anali: 3; Raggi anali molli: 7; Vertebre: 26. This species is distinguished by the following characters: D X,16; A III,7; pectoral rays 19--21 (rarely 21); lateral-line scales 51-59; gill rakers 9 + 23-24; body depth 23.8-25.3% SL; head length 28.5-30.6% HL; snout length 6.8-7.4% SL; longest dorsal spine of mature males 28.7-31.3% SL; caudal fin of mature males 31.8-35.8% SL; absence of black band in soft portion of dorsal fin; a series of indistinct dark bars of unequal width in middle third of standard length, none with pale margins; in life, colour light red with scale centres pale, dark bars reddish brown; an oblique, pale-edged, brownish orange band from snout through eye and across cheek; pelvic fins black with red rays; colour of remaining fins pink to yellowish (Ref. 90856).
Body shape (shape guide): elongated.
The species is usually found over open stretches of coral rubble, and therefore avoid the many predators of coral reefs; form small aggregations that feed on zooplankton above the substratum (Ref. 90856).
