In the context of this species, the male individuals exhibit distinct characteristics that set them apart. Notably, the rostrum is underdeveloped and does not extend ventrally. The fifth pereiopod, a type of appendage, is considerably longer, and the genital pore is typically located on the right side, with occasional occurrences on the left, distinguishing this species from most other Clausocalanus males. The longer leg of the fifth pereiopod surpasses the urosome, while the shorter leg is typically composed of two segments, with the distal segment being relatively small. The somite 2 is slightly lengthier than the other urosome somites.Conversely, the female individuals within this species exhibit their own set of unique traits. The rostrum, when viewed laterally, appears thick, short, and slightly curved, with a bifurcated tip. Furthermore, the coxa of the fifth pereiopod is notably short. The urosome is longer than the fourth pair of legs, and the genital somite is shorter than the subsequent two somites, resulting in a somewhat uneven profile when viewed laterally. One distinctive feature is the large and bulbous seminal receptacle. Additionally, the caudal rami, which are tail-like structures, are twice as long as they are wide.
