Size
- Female: 1.24 – 1.40 mm
- Male: 1.11 – 1.18 mm
Distinguishing characteristics
- Form of urosome somites (female: urosome 2 somite distinctly longer than genital somite, male: no small tooth on right border of urosome somite 2)
- Form of P5
Male
- A1 extends to end of 3rd pedigerous somite
- Right A1 geniculate
- Basis of left P5 is swollen towards proximal end of inner margin, swollen part produced into a small tooth-like spine
- Basis of right P5 exopodite is also swollen
- Flattened joint of P5 1st exopodite segment, with a seta on inner margin, outer thumb short and naked
- Claw-like P5 2nd segment is spoon shaped and without any teeth, but with 2 inner marginal seta
- Urosome somite 2 has no spiny process
Female
- Rostrum pointed
- Last prosome somite produced on each side into acute spine
- P5 is quite symmetrical with 4 segments, distal segment terminates in long spine and 1 short spine, with a further spine on outer mid segment
- Urosome 2-segmented, 2nd somite distinctly longer than the genital somite
Distribution
- Coastal, oceanic
- Subtropical and tropical
- Indian and Pacific Oceans
Ecology
- Sometimes found living in the neustonic layer
- This copepod has been reported as part of several plankton communities, but little is known about its ecology
