Etymology: Pseudoscopelus: Greek, pseudes = false + Greek, skopelos = a lantern fish (Ref. 45335). Lütken did not recognize the presence of photophores on the body, confusing them with pores, but referred to a genus of lanternfish (Scopelus now Myctophum) when he named the genus (Ref. 85782).

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7 - 10; Dorsal soft rays (total): 23 - 26; Anal soft rays: 23 - 26. This species is characterized by the following: dark orobranchial cavity; inclined teeth in the marginal row on the premaxillary are increased in size in the postorbital portion of the bone; presence of teeth on tongue; minute gill rakers usually absent on first gill arch; reduced maxillary (suborbital) photophores disconnected with anteropreopercular photophores; no posteropreopercular photophores and transverse ventral (interventral) photophores; thin cranial roofing bones; short upper jaw, 60.0-71.4% head length (HL), usually less than 66% HL (75% of specimens; mean 65.6%); short pectoral fins, 12.5-21.4% SL, usually less than 16% (88% of specimens; mean 14.9%); group of 4 pores above the second nare; modally 36 vertebrae (Ref. 78617).
