Pennella hawaiiensis Kazachenko & Kurochkin, 1974 

( Fig. 11View FIGURE 11)

Synonyms. None.

Type host and locality. Pentoceros richardsoni  , south Pacific Ocean. 

Morphology. Size: 80–90 mm. Papillae: partial coverage, generally spherical, variable in size and shape, not found in organized groups. Holdfasts: three, two laterals short; dorsal horn shorter. First antenna with four segments, second with two segments. Plumes: dendritic, complex branching.

Remarks. A valid species. Well described, figured and discussed in the original report. An intermediate size Pennella  species parasitic on a unique host, the pelagic armourhead (boarfish), P. richardsoni  . Kazachenko and Kurochkin (1974) documented several specimens of the adult female and younger pre-adult individuals in metamorphosis. Pennella hawaiiensis  resembles P. filosa  but is a smaller parasite; it also superficially resembles and is close in size to P. remorae  , but has a different cephalothoracic papillae configuration, has one less segment on the first antenna, and parasitizes a much different type of host. Pennella hawaiiensis  is the only species of Pennella  other than P. exocoeti  (a smaller parasite which does not possess a dorsal holdfast horn and is found on flyingfish) which exhibits a four-segmented first antenna.
