Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 12; Radios blandos dorsales (total) : 10; Espinas anales: 3; Radios blandos anales: 8. This species is distinguished from its congeners by the following set of characters: scale rows above lateral line 6.5 and between 5th dorsal-fin spine base and lateral line 5½; pored lateral line scales 52- 53; suborbital depth obviously less than the orbit diameter (OD), 72-75% (mean 74%) of OD; dorsal-fin rays are reddish pink with bright yellow margin, anal-fin rays pinkish; no obvious lines of blue spots on body, but usually a blue iridescence in each body scale around dorsal and lateral sides of body from some angles; yellow and red membranes only on upper and lower caudal-fin lobes, respectively (these 2 colors are strongly contrasted; somewhat deeper body, 39-43 (mean 41%) of SL; without bony bulge before and above eye; its caudal fin moderately forked (Ref. 106993).
Body shape (shape guide): short and / or deep; Cross section: compressed.
