Order:Calanoida
Family:Augaptilidae

Description
Size: Female total length 4.8 - 5.75 mm.

The proportional length of the cephalothorax and abdomen are as 61 to 16, so that the abdomen is contained 3.81 times in the length of the anterior region of the body. The cephalic segment is decidedly longer than the thoracic segments together. The head and 1st thoracic segments are separate but thoracic segments 4 and 5 are fused. The posterior thoracic margin is rounded. The forehead is rounded and in the middle line below bears two unequal tuberosities, the upper of which is the smaller, while the lower, over which the chitin is thickened, corresponds to the base of the rostrum. There are no rostral filaments.
The furcal rami are nearly twice as long as broad and bear five setae, of which the outer two arise from the external margin and are considerably shorter than the others. As Sars (1925) notes these outer setae are plumose, while the others appear to be smooth.
The 1st antenna on the right side is unmodified and consists of 24 separate segments, segments 1 and 2 being partially fused. The proximal segments are crowded with large numbers of sensory filaments and the setae arising from the segments are long and slender.
