*: Body length in lateral aspect. | | | | Rem.: | epi-mesopelagic. Overall Depth Range in Sargasso Sea: 0-1000 m (Deevey & Brooks, 1977, Station "S"). 234-820 m at Station T-1 (E Tori Is., E middle Japan) from Furuhashi (1966 a).
The frequency of citations supports a Tethys origin.
The species seems better represented in the Atlantic than in the Pacific (in Wilson, 1942 a, p.198, but not cited in 1950), except in the eastern and south-west region.
Observed in the ballasts of ships at San Francisco.
For Gurney (1927, p.167) this species was found to be common at Suez and at Port Said, but was only taken once in the Canal at Kabret, and probably throughout the Canal, not seen owing to the very small size of the species.

The proportional lengths of the segments of the posterior region (5th thoracic segment to caudal rami) as 11: 53:8: 6: 8: 14 = 100. Caudal rami are one and three-fourths times the length of the anal segment and about two and a half times as long as wide. The anal segment and caudal rami are in most examples covered with stout chitin, which in some instances is stained a rich orange-red colour.The various segments of A1 have the proportional lengths as 14:24:37:10:5:10 = 100. In Mxp the two spines arising from the 2nd basal segment are subequal.
Oncaea media minor Sewell,1947 (F,M)

Nota:
The proportional lengths of the various segments of the posterior region of the body (5th thoracic segment to caudal rami) as 11:51:8:6:9:15 = 100. In this form the caudal rami appear to be somewhat more slender than in forma major. The proportional lengths of the segments of A1 as 14 : 25: 37: 10: 4: 10 = 100.
Rem.: often confused with Oncaea scottodicarloi.
For Boxshall (1977, p.134) O. media and O. curta are closely related species and are usually separated primarily on the basis of the proportional lengths of the urosome somites in the females. Numerous specimens have been found which possess body proportions intermediate between the two species. The wide range of body form exhibited by female O. curta includes forms that approach typical O. media and it is necessary now to reappraise the criteria used to separate these two species (see Tables 4 and 5 above).
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 5 corresponding to small sac-spawning detritivorous.

| | | | Oncaea media Giesbrecht is often mixed up with O. scottodicarloi and O. waldemari. Morphological separation between the first two species are given in detail by Heron & Bradford-Grieve (1995), who also pointed out that Giesbrecht´s drawing of the female urosome of O. media (his plate 47, fig. 11) in fact showed the urosome of O. scottodicarloi. Thus, Giesbrecht´s figure of the female urosome shown in this database (above) should be omitted or a corresponding remark should be added to the legend. For a morphological distinction between all three species of the media-complex see Böttger-Schnack (2001).
|
| | | The female urosome of Oncaea media figured by Razouls 1974 (his Fig. 5A) was obviously not based on an adult specimen (deficient number of urosome segments). Later on, this (incorrect) figure was also included in the publication by Conway et al (2003).
