Morphology | Morphometrics
soft rays: 7 - 8. This small species has the following characteristics: a broad head and moderate snout, eyes set dorsolaterally; second dorsal- and anal-fin rays I,7-I,8 (usually I,8); pectoral-fin rays 17-18 (usually 17); longitudinal scales 24; TRB 6; nape naked; pelvic fin rounded, cup-like, with fleshy, rounded pelvic spine lobes; tongue round; lower gill opening margin attached at level of preopercular margin; gill membranes broadly joined to isthmus; live color translucent with orange markings and some melanophores (Ref. 58271).
This species appears to be extremely cryptic, collected five times only in a total of 75 general ichthyocide collections, with 4 of those collections from a specific habitat, shallow patch reefs (0-4.6 m) with good circulation. The sixth collection from that specific habitat only occurred after a number of futile attempts to collect more individuals for photographs. This particular species was reported to have been at Haleiwa, O’ahu, living on Porites compressa (Ref. 58271). Benthic (Ref. 58302).
