RESUMO

Miracetyma kawa sp. nov. é proposta. Os espécimens foram coletados dos filamentos branquiais de Rhaphiodon vulpinus Agassiz, 1829. A espécie nova difere da espécie-tipo M. etimaruya no tamanho do corpo, no formato do cefalotórax, por apresentar extensões cuticulares somente nas margens interna e externa distais do terceiro segmento da antena e no formato e ornamentação dos ramos das pernas.

ABSTRACT

Miracetyma kawa sp. nov. is proposed. The specimens were collected from the gill filaments of Rhaphiodum vulpinun Agassiz, 1829. The new species differs from the type-species, M. etimaruya in size and in the shape of the cephalothorax. Also, the cuticular extensions of the third antennal segment are limited to the internal and external distal margins and the rami of the legs have different shapes and armature.

Key words: Copepoda; Poecilostomatoida; Ergasilidae; Parasites of Fishes; Amazônia
