Escal appendage pattern B; esca with a stout internally pigmented anterior appendage, shorter than escal bulb in smaller specimens (60 mm) to slightly longer than length of bulb in largest specimen (150 mm), usually bearing a compressed papilla and two tapering filaments on distal tip; several small tapering filaments along posterior margin of anterior escal appendage of 60-mm specimen; papilla and filaments of anterior escal appendage unpigmented; a pair of minute unpigmented filamentous medial escal appendages present in all but 115-mm specimen; a rounded or truncated terminal escal papilla with a distal streak of pigment; an unpigmented, unbranched tapering posterior escal appendage as long as or shorter than escal bulb; lateral and anterolateral appendages absent.
Subopercle relatively short and broad, without indentation on posterodorsal margin; length of ventral fork of opercle 25.2–32.2% SL; ratio of lengths of dorsal and ventral forks of opercle 0.52–0.59.Epibranchial teeth absent; teeth present on pharyngobranchial II; total number of teeth in upper jaw 20–37, in lower jaw 22–48; number of teeth on vomer 4–7; dorsal-fin rays 5–7; anal-fin rays 4; pectoral-fin rays 17–19.
Measurements in percent of standard length: head length 35.0–46.2; head depth 36.3–48.8; premaxilla length 25.0–35.0; lower jaw length 38.3–50.0; illicium length 19.1–28.3.0.
Oneirodes notius is most similar to O. acanthias and O. thompsoni. Although the high pectoral-fin ray count of O. notius (17–19) is helpful in distinguishing this species from its congeners, the characters of the esca are the only satisfactory means of identification. The shape of the frontal bones of O. notius differs from those of all other species of Oneirodes examined osteologically.
Oneirodes notius is known only from subantarctic waters: three stations from the Atlantic sector of the Southern Ocean along the 40th parallel between 30°30'W and 48°02'W, and seven from the Pacific sector extending from off New Zealand at 46°53'S, 179°48'W, southeast to 65°47'S, 88°48'W. The holotype was collected at 62°13'S, 95°39'W. Based on maximum depth reached by fishing gear, O. notius appears to have a relatively wide vertical distribution, from about 700 to 2000 m, with the greatest concentration between 800 and 1100 m.

As with most oneirodid taxa, males of the genus Oneirodes are free-living and presumed non-parasitic.
Known from 17 metamorphosed females (30–150 mm).
