Pennella

Hogans, W. E., 2017, Review of Pennella Oken, 1816 (Copepoda: Pennellidae) with a description of Pennella benzi sp. nov., a parasite of Escolar, Lepidocybium flavobrunneum (Pisces) in the northwest Atlantic Ocean, Zootaxa 4244 (1), pp. 1-38 : 33

Undetermined Pennella sp.

A Pennella which is likely a distinct species, but has not previously been assigned to any known member of the genus has been documented. Nagasawa et al. (1984) identified a Pennella sp. from the saury (Cololabris saira) in the north Pacific. The parasite is clearly different from any of its congeners based on photographs of recovered specimens ( Nagasawa et al. 1984). The cephalothoracic papillae are dendritic and form a large mass covering the entire apical end of the parasite, a feature not yet reported from any other species of Pennella . Nagasawa et al. (1984, 1988) reported on the population dynamics and geographical distribution of the parasite; the authors were reluctant to classify the specimens further than the generic diagnosis based on the poor taxonomic condition of the genus.
