Labidocera euchaeta f. minor     (Copepod)
Organism information awaits expert curation
Class: Maxillopoda

Size (female): length 1.8-2.4 mm

The proportional lengths of the cephalothorax and abdomen are as 35 to 11, so that the abdomen is contained 3.182 times in the length of the anterior region of the body.
The abdomen consists of three segments and the furcal rami. The abdomen is symmetrical bu the 3rd segment and the left furcal ramus are fused. The furcal rami are slightly asymmetrical, that on the left side being slightly broader than that on the right.
The 1st antenna reaches back to about the posterior margin of the genital segment. It consists of 23 free segments; segments 6 and 7 are separate but segments 8 and 9, and 24 and 25 respectively are fused together.
The segments distal to 13 all show at least some degree of diminution in size as we pass from the smaller to the larger form, whereas in other species this decrease in the proportional length does not occur till we reach segment 19.
