Taxonomy Oncaeid species of the notopus-group are characterized by a long, free exopod segment on leg 5 bearing two terminal setae.
"The type species of the group, O. notopus, was originally recorded from the tropical Pacific Ocean (Giesbrecht 1891) and was subsequently redescribed by the same author in more detail in his comprehensive monograph on the copepod fauna of the Gulf of Naples (Giesbrecht 1893 [“1892”]). The redescription was based on the original (female) copepod material from the Pacific, and the species was explicitely quoted as an “auswärtige Species” (= foreign species) by Giesbrecht, while the author did not record it from the Mediterranean Sea itself (1893 [“1892”], p. 774). The males of Giesbrecht´s species are unknown. Over the following 8 decades, Giesbrecht´s description was the only taxonomic basis known for the identification of notopus-type copepods in the oceans and subsequent authors – including Giesbrecht himself - used to identify oncaeid copepods showing an elongate leg 5 exopod as O. notopus (e.g. Sars 1900, Giesbrecht 1902, Tanaka 1960).
In 1977, Heron studied the taxonomy of notopus-type copepods from the SW Pacific Antarctic area in more detail in comparison with Giesbrecht´s type species loaned from the collections of the Stazione di Zoologica ´A. Dohrn` di Napoli, Naples. She described 4 new species, which differed from the genuine O. notopus primarily in the relative lengths of the two exopodal setae on leg 5 as well as in proportional spine lengths on the swimming legs, and she provided figures of the swimming legs of Giesbrecht´s O. notopus, which had not been figured by Giesbrecht himself. In the same account, she synonymized O. notopus sensu Sars and O. notopus sensu Tanaka with the newly described O. parila, while O. notopus sensu Giesbrecht 1902 was synonymized with the new species O. prolata. In subsequent taxonomic studies, Heron and her co-workers recorded and (re)described species of the notopus-group also from the Arctic Ocean (Heron et al. 1984), from the SW Pacific off New Zealand (Heron and Bradford-Grieve 1995) and from the open NE Pacific and inland waters of Washington state (Heron and Frost 2000), where they found another new species, O. grossa. In many cases, several species of the notopus-group co-occurred at one station. The authors also complemented their earlier species descriptions by including the morphology of some hitherto unknown males [O. parila, cf. Heron et al. (1984), and O. prolata, cf. Heron and Bradford-Grieve (1995)]."
