Three New Species of Colobomatus (Copepoda: Philichthyidae) Parasitic in the Mandibular Canals of Haemulid Fishes

Résumé du livre

Three new species of Colobomatus are described from the mandibular canals of three genera of American haemulid fishes. These are the first species of Colobomatus reported from the Haemulidae and are the first described with abdominal processes in the female. Males of two of the new species are described. One of the species (C. quadrifarius) is restricted to the Eastern Pacific and the other two (C. caribbei and C. belizensis) to the western Atlantic. Data are presented to suggest that an optimum host size exists for parasite infestation, accompanied by diminishing infestations in smaller and larger size groups.
