Male: 16, P5.
Plate 2 issued from : H.B. Owre & M. Foyo in Fauna Caribaea, 1, Crustacea, 1: Copepoda. Copepods of the Florida Current. 1967. [p.82, Fig.553].
Female (from 23°36'N, 83°06'W): 553, urosome.
Plate 3 issued from : H.B. Owre & M. Foyo in Fauna Caribaea, 1, Crustacea, 1: Copepoda. Copepods of the Florida Current. 1967. [p.82, Fig.554].
Female: 554, A2.
Nota: Endopod 2-segmented, the first of which is about twice as long as the second; exopod 7-segmented.

Female: 555, Md (biting edge of ghathosytome).

Female: 556, Md (distal part of palp).
Nota: Endopod 3-segmented and beras distally 6 setae, 3 long and 3 short; Exopod 4-segmented with 5 setae, thick structures, hardly to be termed setae, one on each of the first three segments and two on the terminal segment.
Plate 6 issued from : H.B. Owre & M. Foyo in Fauna Caribaea, 1, Crustacea, 1: Copepoda. Copepods of the Florida Current. 1967. [p.83].
Female: Proportional lengths of the somites of the urosome.
Nota: The urosome is not as elongated as shown in Sars' (1925) drawings of E. digitatus.

Remarks

bathypelagic. Known to occur at 900 m depth after Matthews (1972, p.29).
Owre & Foyo (1967) provisionally assigned to E. digitatus Sars (1924-25) although it differs in size, length of A1 and in setation and digitation of the swimming legs. Sars stated that the filaments were very small and his illustrations do not depict rigidity. A1 are extraordinary long, 12.4 mm on the left and 13.0 mm on the right, extending posterior to the rami by 6-7 segments
First occurrence in Indonesian waters by Matsuura & al. (2010).

In ''affinis"" Group after Matthews (1972, p.64) {See remarks in Euaugaptilus genus}.
