Scale : single line = 0.1 mm ; double line = 0.05 mm.

Nota Female (great form):
- Anal segment broader than long.
- Caudal rami: length : broadth = 2.5 : 1. The insertion of Se divides the lateral margin into a proximal and a distal portion, the relations of which are 2 : 7; Si ciliatedon the outer side; Si naked, length= abdominal segments 3-5 + caudal rami.
- P5 with 1 naked basal seta on a papilla, it is bent and shows upwards; there is1 terminal thick seta, the latter reaches the posterior margin of abdominal segments 1-2 and is ciliated;
- Se, all St and the terminal seta of P5 are ciliated with strong yellow cilia.
- A1 reaches the posterir margin of yjoracic segment 3 or 2.
- Rostrum acute, bent, downwards.
- Genital segment with a yuft of tender hairs on the sides just behind the genital swelling.
- Small spinules on the sides of abdominal segment1-2 and 3 absent (or only very weak in some specimens) In some specimens abdomonal segment 5 has fine spinules on the ventral side, and sometimes also on the dorsal aspect of the posterior margin) Abdominal 1-2 - 4 are naked.
- Md has 2 conspicuous hooks at the end of basis; the median hook is longer and bears on the median side a row of about 10 strong spines; both hooks bear at the end on each side a row of fine cilia, as a whole resembling two membranes; the hooks ebd in a short spine each; endopod bears 4 hairs of which the proximal is stronger and finely ciliated, on the opposite side there is a ciliated seta.

Nota Male:
- Ratio prosome : urosome = 1.56.
- Forehead slightly bent downwards; withoit a rostral horn.
Ratio prosome (cephalon-4th thoracic segment) : urosome (5th thoracic segment-caudal rami) = 1.56.
- Md has a somewhat different shape: the median hook of basis is shorter, almost straight, with spines on both sides; the lateral hook resembles that of the female, only, there is an additional spine on either side.
- Abdominal segment 5 (anal) has fine spinules on the ventral side of the posterior margin.
- In some males the setae of the caudal rami have the same yellow ciliation as in the female.

Female I (great form): Armature of the swimming legs P1 to P4 .

Nota: Proportion of the exopod of P4 terminal spine : whole exopod = 8 : 9. Endopod segment 3 of P4 bears a strong seta on the inner margin in the most proximal position (only seen in the mature female).
Older copepodite have a thick and yellow ciliated seta on P6, like the terminal seta on P5.
- All copepodites bear a typical rostrum as the females.

Female (small form): 107, rostrum (lateral); 108, habitus (dorsal)/
Scale bar = 100 µm.

Nota:
- Anal segment broader than long.
- Caudal rami: length : breadth = 2 : 1; proximal : distal portion of the lateral margin = 2 : 3; length of the external seta (Se) = 1.3 x caudal rami; length of the inner seta (Si) = abdominal segments 3-5 + caudal rami. Caudal setae with fine, colourless and transparent cilia.
- P5 as in the species type.
- A1 reaches the posterior margin of the 2nd thoracic segment.
- Rostrum acute, bent downwards.
- Genital segment without hairs on the sides.
- Small spinules absent on the abdomen, all abdominal segments
- Md similar to samples from Cochin Backwaters (great form), however, measures 1 naked./3 in length.
- Exopodal segment 3 of P4 bears 1 strong seta similar to samples from Cochin Backwater (great form).
- Both forms occurred in water with more than 22 p.1000 salinity, although sometimes found in a 4 p.1000 sample.The small form closely resembles O. brevicornis forma aruensis Früchtl, 1924 from Aru Islands (Indonesia) in brackish water. The only difference is the shape of the terminal hooks of Md; they are sharply pointed in the forma aruensis, whereas in the small Cochin animals they resemble those of the great form.
Both the small and the great form occurred in the same samples in the Cochin Backwater, but intermediate forms were also seen.
