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).

生態學
海洋 深海區的; 深度上下限 30 - 2390 m (Ref. 56658), usually 50 - 1870 m (Ref. 85782). 深水域; 46°N - 36°S, 0°E - 0°W
Circum sub- and tropical: Atlantic Ocean (from 46°N-36°S, 7°W-88°W). Pacific Ocean (33°N-27°S, 99°W-121°E), including off Japan and several records from the Western Indian Ocean (Ref. 85782). The northern occurrence in Atlantic and Pacific most likely due to transportation by Gulf Stream and Kuroshio, resp. (Ref. 78616).

Maturity: Lm ? range ? - ? cm
Max length : 20.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 47377); common length : 10.1 cm SL 雄魚/尚未辨別雌雄; (Ref. 13608)
背的軟條 (總數): 21-23; 臀鰭軟條: 20 - 24; 脊椎骨: 36 - 38. This species can be distinguished from P. paxtoni by dentition and photophore pattern with innermost premaxillary teeth in mesial row not extremely elongated, when mouth is closed teeth not reaching the contralateral premaxilla (vs. innermost premaxillary teeth in mesial row very elongate, reaching contralateral premaxilla when mouth is closed); teeth of mesial row of premaxilla and internalmost row of dentary slightly curved (vs. teeth of mesial rows of premaxilla and internalmost row of dentary straight); mesial series of premaxillary teeth arranged in transverse rows of 1-5 rows of teeth (vs. mesial series of premaxillary teeth arranged in transverse rows of 1-3 rows of teeth) (Ref. 85782).
A meso- to bathypelagic (Ref. 85782). One record at 4,631m deep (Ref. 78616).
