Diagnosis . In this species the photophores are arranged as in 
Diaphus hypolucens PARR. The upper antorbital is similar and the lower 
very different or on the lower front edge of the eye, also always a 
marginal lower or infraocular photophore midway on lower eye edge. The 
latter is apparently a character shared with Diaphus metopoolampu3 (00C00).
