Body depth 2.3-2.85 in SL, and body width 2.3-2.7 in the depth; eye diameter 2.7-3.1 in head length; first dorsal spine 2.0-2.9 in second spine; second dorsal spine 2.1-2.6, and third dorsal spine 2.2-2.7 in head length; spine of second dorsal fin 2.3-2.6, and second anal spine 2.5-2.9 in head length; pelvic-fin length 4.3-5.3, and caudal-peduncle length 4.9-5.9 in SL. Distance from insertion of pelvic spine to anal-fin origin 4.2-5.5 in SL.
