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);  astronesthidens: Named for the characteristic shape of the marginal premaxillary teeth, resembling the dentition in the stomiiform genus Astronesthes..

Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 7 - 8; членистые (мягкие) лучи спинного плавника (общее число) : 23 - 28; членистые (мягкие) лучи анального плавника: 23 - 28; позвонки: 36 - 37.

Estimates based on models

Preferred temperature (Ref. 123201): 2.5 - 3.1, mean 2.8 °C (based on 1162 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.2 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
