Short description
Dorsal
soft rays
(total): 13-15;
Anal
soft rays: 15 - 16. This species is a member of the subgenus Photonectes and is distinguished by the following set 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 38-39; and IP photophores begin halfway posteriorly on the isthmus. Within the subgenus, P. barnetti differs from P. achirus, P. caerulescens, P. coffea, and P. corynodes by gill-filament length on first branchial arch reduced (vs. normal or very long); differs from P. phyllopogon by dorsal-fin rays 13-15 (vs. 20-23) and IV photophores 38-39 (vs. 30–31); differs from P. mirabilis by blue luminous tissue absent (vs. present) and barbel with elongate stem and whiplike filament (vs. short stem and bifid filament) (Ref. 87305).
