Etymology: Photonectes: Greek, photos = light + Greek, nekton = swimmer (Ref. 45335); corynodes: Name from the Greek word koryne, meaning mace or club, referring to the appearance of the terminal bulb (Ref. 87305).

Morphology | Morphometrics
soft rays: 16. This species of the subgenus Photonectes based on the following combination of characters: dorsal- and anal-fin rays not covered with black fleshy skin; pectoral fins absent; pelvic fins inserted closer to the caudal-fin base; IV photophores 34; and IP photophores begin halfway posteriorly on the isthmus. Differs from all other species in the subgenus except Photonectes mirabilis by a barbel with a small side-branch on the terminal filament. Differs from P. mirabilis in gill filaments “normal” (vs. very reduced); jaw teeth variable length (vs. short) canines; 16 anal-fin rays (vs. 19–20); no blue luminous tissue (vs. present); and no light organs inside the lower jaw (vs. three pairs) (Ref. 87305).
