Cyclapsis Sars, 1865

Diagnosis (sensu Gerken 2013): Female. Carapace longer than pereon, pleon longer than pereon and carapace together; eyelobe extending to the end of the pseudorostral lobes or beyond; antennal notch present, open; branchial siphons short. Pleonite 6 longer than wide. Pereopods 2–4 with ischium. Uropod endopod uniarticulate. Uropod exopod article 1 shorter than article 2. Male. With five pairs of pleopods.

Remarks. According to Haye (2007) Cyclaspis is the most specious of the bodotriid genera because of the broad generic diagnosis. They share some characters e.g., pseudorostral lappets not extending beyond the frontal lobe, well developed eye lenses, distal article of main flagellum of the antenna 1 with at least one aesthetasc, basis of the maxilliped 3 extended dorsodistally over ischium beyond the articulation of the ischium and merus, pereopod 2 and 4 with ischium present, lateral pegs in the abdomen, pleonite 6 longer than wide and uropod endopod uniarticulate; but according to Haye (ídem) there exists “a great morphological variability within the genus Cyclaspis and, following a detailed analysis, it should be divided into several related genera”.
