Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 8; Radios blandos dorsales (total) : 16; Espinas anales: 3; Radios blandos anales: 14. This species is distinguished from Leiognathus equulus (the only other species of leiognathid known to possess a non-sexually dimorphic light organ system) by the having no occipital hump (vs. pronounced hump); with a mildly sloping predorsal profile (vs. strongly curved, creating the image of an arched back); with frontal and lateral ethmoid ossifications that project anterodorsally and extend well anterior of the orbit to form a distinct preorbital protuberance (vs. slight bulge above orbit); and unexposed nuchal spine in lateral view (vs. exposed and projecting, particularly distally) (Ref. 76780).
