Morphology | Morphometrics
Distinguished from its congeners by a unique combination of characters: two unpaired median pre-dorsal plates, body width 10.0-13.0% of post-dorsal fin length, inter-orbital distance between 10.6-13.0% of post-dorsal fin length, inter-orbital distance between 25.0-29.0% of eye-to-dorsal fin length; low number of jaw teeth (12-15 teeth in upper left jaw, 9-13 in lower left jaw), and pre-dorsal fin body pigmentation not formed into distinct lines between longitudinal rows of odontodes (Ref. 54475).
