TABLE 2. Affinities and differences between the cnidomes of the medusae of Corymorpha tropica sp. nov. and C. bigelowi (Maas, 1905), in µm. Some indeterminate types of nematocysts belonging to the former were tentatively compared to their potential counterparts in the latter, notably on the account of their general shape.
