Morphology | Morphometrics
soft rays: 20. This species is diagnosed by the following characters: total dorsal-fin elements 30-31; mode of D XX,11, A II,20, Pectoral 13; a short orbital and nasal cirrus on each side and unbranched, nasal cirrus longer than nasal tube; first 3 dorsal-fin spine bases close, first and second closest, widest gap between third and fourth; first spine longer or equal to second, third spine 1/2 to 3/4 of second and fourth spine shortest, forming notched dorsal fin outline in juveniles, females, and many mature males (males with the most extended first dorsal-fin spines can have a concave, but not notched, fin outline); mature males with greatly extended first dorsal-fin spine (when folded down straight reaching back to base of 8th-15th dorsal-fin spines) followed by a shorter second spine, a distal red-orange band outlined in white above and below on first few spinous membranes; females and immature males >10 mm SL with first and second dorsal-fin spines longer or equal to 12th spine (first two when folded down straight reaching back to 6th-7th spine base), first spine banded black and white; juveniles <10 mm SL with first and second dorsal-fin spines shorter than 12th spine (first two when folded down straight reaching back to 5th-6th spine base), first spine dark with light tip; all stages with last (or 2nd to last) dorsal spine shortest, ¼ to ½ longest soft ray; interorbital head pores including midline CP plus three adjacent pairs (PAF, PI, PLI) when complete (which is infrequent); evenly dispersed stippling of fine black spots over cranium (all stages except blackhead males); males and females without white spots on top of head in life; females, immature males, and some juveniles with midline melanophore stripe on snout not extending back past posterior nostril; lower pectoral-fin-base dark spots comprising one anterior rounded spot or short oblique line slanted down and sometimes additional spots (Ref. 85868).
