(here designated). Diagnosis As for the new tribe. Etymology The new genus is named after the state and the river from which it is here described, namely Paraná , and ‘ dopsis ’, referring to the stem of Cypridopsis . Differential diagnosis Paranadopsis gen. nov. can be distinguished from all other cypridopsine genera by the combination of the valve and limb morphology, including the strong reduction of size and chaetotaxy of segments in various limbs, especially in the A1 (see above, diagnosis of new tribe) (see Table 3 ).
