A new species of Lernaea L. (Copepoda: Cyclopoida) from Brazil, with notes on its ontogeny

A new species of Lernaea, closely related to L. cyprinacea, is described from both native and introduced fish species at a fish farming facility in Rio Grande do Sul, Brazil. All life-cycle stages of the new species, L. devastatrix, can be distinguished from L. cyprinacea by the reflexed claw on its antenna. A partial scheme of homologies of the antennulary segments is proposed, and the development of the segmentation and setation patterns is traced from CoIII to adults of both sexes. New interpretations are proposed of the homology of the antennary claw and of the maxillipedal endopod in lernaeids.
