Morphology | Morphometrics
A medium-sized scorpionfish with the following combination of characters: dorsal-fin spines
12; vertebrae 26; tympanic spines present; upper-jaw lip thin, not covering the premaxillary tooth band laterally; maxilla unscaled; 50 scale rows in longitudinal series; body moderately deep (30.9% of SL); orbit diameter large (12.8% of SL); third dorsal-fin spine long (15.3% of SL); pelvic-fin spine short (9.6% of SL); head profile slightly convex; gas bladder absent; coloration bright red, with no distinct dark markings on back
or spinous portion of dorsal fin (Ref. 82588).
Known only from off Puerto López, Manabí, Ecuador and it is probably a deepwater species, presumable rarely caught by the longline fisheries off Puerto López.
