Homoeoscelis meridionalis sp. nov. (Copepoda, Nicothoidae) parasitic on two cumaceans from southern South America with comments on its biology, and partial redescription of H. frigida Hansen, 1923

The adult female and male, and the copepodite stage of the nicothoid copepod Homoeoscelis meridionalis sp. nov. are described. This parasite infests the branchial chambers of two closely related cumaceans from southern South America: Diastylis planifrons and D. fabrizioi. The maxilliped of the adult...
