Meso-bathypelagic-abyssopelagic. 2000-3010 m at Station T-1 (E Tori Is., E middle Japan) from Furuhashi (1966 a).
The locality records from the Antarctic and the Arctic oceans are not taken into account because of the synonymies established by Heron (1977) between this species and Oncaea parila. For Heron & Frost (2000, p.1042) the P5 of O. parila and O. notopus, both with the lengths of the two terminal setae being approximately equal, display one of the characters useful in distinguishing each of them from other similar species. O. notopus Giesbrecht, 1891, differs from O. parila by a greater size and the relatively longer spines on exopods and endopods of P1-P4.
The presence in the Bay of Lübeck needs confirmation.
C.B. Wilson (1950) refers to Sars (1900) what puts some doubt on his identifications.
According to Böttger-Schnack (2011, p.325) in ecological notes, the taxonomic re-examination of notopus -type oncaeids from different areas in the Mediterranean Sea leads to the assumption that Oncaea serrulata is the sole representative of this group in the area. In his opinion people have always misidentified the species, because nobody ever realized that Giesbrecht - although having included the species description in the Naples monography - NEVER recorded the species from the Mediterranean himself, but described it under the topic: "Auswärtige Species" (= "foreign species"). All subsequent workers just looked at the most characteristic feature of the species, the elongate P5, but this is only the typical character of the notopus-GROUP of oncaeids, which now includes 7 species worldwide. The zoogeographical records of Oncaea notopus in the Mediterranean and Red Seas (e.g Loc. and world-wide chart in Razouls & al., 2010) are disputable.
