Mesocyclops

Belongs within: Cyclopidae.

Mesocyclops is a genus of relatively slender cyclopid copepods with elongate antennae (Sars 1914).

Characters (Sars 1914): Body more or less slender, with anterior division generally rather tumid, posterior very slender. Epimeral parts of trunk-segments scarcely prominent laterally and not visible in dorsal aspect of animal. Last trunk-segment very small, not produced laterally. Genital segment in female rather elongated, very little dilated in front. Caudal rami of moderate length or very short, with all apical setae generally well developed. Anterior antennae slender and elongated, generally 17-articulate. Posterior antennae likewise slender, with apical setae long and curved. Maxillipeds rather fully developed. Natatory legs with both rami 3-articulate; terminal joint of outer ramus in all pairs with only 2 spines outside, its inner edge carrying in the 1st pair 2, in the other pairs 3 setae; terminal joint of inner ramus unusually prolonged, especially in posterior pairs. Last pair of legs very small and generally biarticulate, distal joint carrying 2 slender subequal setae. Seminal receptacle in all species of characteristic form, anterior part short, bilobular, posterior greatly prolonged, tongue-shaped.
