Pennella diodontis Oken, 1816 (Fig. 7) Synonyms. Pennella cervicornis Heegaard, 1943, P. plumosa (Dekay, 1844) Type host and locality. Diodon sexmaculatus, Philippines. Morphology. Size: 24–28 mm. Papillae: partial coverage, clavate and club-like, consistent in size and shape, not found in organized groups. Holdfasts: two only, short. First antenna with three segments, second with two segments. Plumes: simple, single. Remarks. A valid species. Original description from porcupine fish, Diodon sexmaculatus (= D. holacanthus) (Oken 1816); redescription from the same host species, Ceylon (Kirtisinghe 1932; Fig. 7). Considered incorrectly as infesting two host genera: Lophius and Diodon (Wilson 1917). The history of P. diodontis was often confused with that of P. sagitta (Wilson 1917), however, P. diodontis reported from Lophius was an error of Blainville (1822) based on a poor description and incorrect host identification; P. diodontis is in fact a parasite of porcupine fish (Diodontidae: Diodon) and P. sagitta ... : Published as part of Hogans, W.
