Espinhos dorsais (total) : 13; Raios dorsais (total) : 13 - 15; Espinhos anais: 3; Raios anais : 6 - 7. Head spines weak - nasal, preocular, postocular, tympanic and parietal spines present, supraocular, coronal and nuchal spines absent (Ref. 27437). Notch on dorsal fin shallow; 2nd anal fin spine is of the same length or shorter than the 3rd (Ref. 27437). Caudal fin moderately indented (Ref. 6885). Light red and mottled with olive on back, lower sides flushed with yellow; light red stripe along lateral line; lips blackened; fins red with some light green or yellow (Ref. 27437).
