🐟 Physical Description

Dorsal spines (total): 7; Dorsal soft rays (total): 22 - 24; Vertebrae: 35 - 36. Distinguished from all other species of Pseudoscopelus by the possession of longitudinal preopercular photophores, extending dorsally to the middle of the preopercle. Differs further from all congeners, except Pseudoscopelus scutatus, by the following characters: concave snout; presence of supraventral-fin photophores; absence of pectoral-fin photophores, pectoral-fin axillary photophores, ventral-fin photophores and ventral-fin axillary photophores; preventral-fin photophores and postventral-fin photophores continuous; and distal radials of the first dorsal fin developed on a plate-like structure . : elongated.
