| Abstract |
Two new species of the genus Tryphoema Monard, 1926 (Copepoda: Harpacticoida: Rhizotrichidae) are described from sandy sediments in coastal shallow waters of the islands Madeira and Porto Santo. Tryphoema werneri sp. nov. occurs on both islands, while Tryphoema irmgardae sp. nov. was solely found on Madeira. Tryphoema werneri sp. nov. displays one-segmented exopods at the swimming legs 2–4, which are two-segmented in congeners. Tryphoema irmgardae sp. nov. retains four setae on the endopods of the swimming legs 2–4 while all other representatives of the genus display at most 3 setae. Both species differ from each other in many morphological characters especially concerning the armature of the swimming legs 1–4 and their exopodal segmentation, the length of the furcal setae and the ornamentation of the maxilliped. By contrast, some synapomorphies between Tryphoema irmgardae sp. nov. and Tryphoema porca Monard, 1926 (known from shallow waters of the Mediterranean and the English Channel) have been identified and are discussed. Furthermore, a revised key to the species of the genus Tryphoema is provided. |
