Euaugaptilus latifrons   (Sars, G. O.,  1907) (Copepod)
Organism information awaits expert curation
Class: Maxillopoda

Size: Female total length 4.8 - 5.3 mm.

The proportional lengths of the cephalothorax and abdomen are as 66 to 19, so that the abdomen is contained 3.47 times in length of the anterior region of the body.
The head and 1st thoracic segment are separate and the length of the cephalon is longer than that of the combined thoracic segments in the proportion of 9 to 7. Sars in his description states that the anterior region of the head, when viewed in profile, is truncated; in my examples the forehead is uniformly rounded, and situated below in the middle line are two rounded prominences of which the upper is small, while the lower is large and prominent and possesses thickened chitin. There is no trace of any rostral filaments. The 4th and 5th thoracic segments are fused together and the posterior thoracic margin is rounded.
The abdomen consists of three segments. The genital segment is long and symmetrical and bears on its ventral aspect, about the middle of its length, a well marked genital protuberance. The 2nd segment is short. The anal segment is nearly as long as the genital segment.
The furcal rami are comparatively short, being about half the length of the anal segment; their length is about twice their breath. O the five setae arising from them the inner one is shorter and more slender than the junction of the proximal and middle thirds.
The 1st antenna is slightly longer than the body and consists of 25 free segments. The appendage is well provided with long and delicate setae.
