Cornucalanus simplex   Wolfenden,  1905 (Copepod)
Organism information awaits expert curation
Class: Maxillopoda

Size (female): length 4.0 - 6.3 mm.

The proportional length of the cephalothorax and abdomen are as 161 to 51, the abdomen thus being contained 3.2 times in the length of the anterior region of the body. There is nos pine in the frontal region. The posterior thoracic margin is produced backwards in a triangular plate that is rounded at the apex. The abdomen consists of four segment having with the furcal rami. The genital swelling on the ventral aspect is but slightly enlarged. There are a few hairs on the ventral aspect of the genital segment. The rest of the abdomen is devoid of hairs. The 1st antenna reaches to the posterior end of the thorax. In the maxilliped, there is a row of spines on the 2nd basal joint, the spines increasing in size distally but there is no isolated large spine just beyond the end of the row. The two claw-like spines on the 2nd and 3rd segments of the maxilliped appear to be rather longer and the terminal portion, lying distal to the row of long spines and bearing a row of closely-set small spines, also seems to be longer.
