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); lavenbergi: Named after Robert J. Lavenberg, for his contribution to the knowledge of the genus Pseudoscopelus.

Morphology | Morphometrics
Vertebrae: 37 - 39. Differs from other species of the genus by the following three unique characters: random trunk photophores in broad band of three or more rows; postventral-fin photophores short, not extending to anus, and reaching anteriorly to very close to pelvic-fin origin; absence of maxillary photophores and presence of anteropreopercular photophores (Ref. 75982).
