Novel morphological and molecular data for Corynosoma hannae Zdzitowiecki, 1984 (Acanthocephala: Polymorphidae) from teleosts, fish-eating birds and pinnipeds from New Zealand
چکیده انگلیسی


- Specimens of Corynosoma hannae are characterised from the intestine of pinnipeds.
- Immature specimens of C. hannae are described from shags and penguins.
- Cystacanths of C. hannae are described from fish paratenic hosts.
- Partial cox1 sequence were generated for C. hannae collected from all hosts.
- Phylogenetic analyses revealed a close relationship between C. hannae and C. australe.

The polymorphid acanthocephalan, Corynosoma hannae Zdzitowiecki, 1984 is characterised on the basis of newly collected material from a New Zealand sea lion, Phocarctos hookeri (Gray), and long-nosed fur seal, Arctophoca forsteri (Lesson) (definitive hosts), and from Stewart Island shags, Leucocarbo chalconotus (Gray), spotted shags, Phalacrocorax punctatus (Sparrman) and yellow-eyed penguins, Megadyptes antipodes (Hombron & Jacquinot) (non-definitive hosts) from New Zealand. Specimens are described in detail and scanning electron micrographs for C. hannae are provided. Additionally, cystacanths of C. hannae are reported and described for the first time from the body cavity and mesenteries of New Zealand brill, Colistium guntheri (Hutton) and from New Zealand sole, Peltorhamphus novaezeelandiae Günther from Kaka Point, Otago in New Zealand. Partial sequence data for the mitochondrial cytochrome c oxidase 1 gene (cox1) for adults, immature specimens and cystacanths of C. hannae were obtained. Phylogenetic analyses of the newly-generated sequences and for available cox1 sequences of Corynosoma spp. revealed a close relationship between C. hannae and C. australe Johnston, 1937, both species infecting pinnipeds in the Southern Hemisphere. However, a morphological comparison of the species suggests that C. hannae mostly closely resembles C. evae Zdzitowiecki, 1984 and C. semerme (Forssell, 1904), the latter of which occurs in pinnipeds in the Northern Hemisphere.
