5D047A7FFFA52407FEEBA2F3FEE2FA91.taxon	discussion	Comment: Contracaecum spheniscus was described in the proceedings of a congress in 1970, based only on male specimen found in the proventriculus of S. magellanicus from the La Plata Zoological Garden. Boero et al. (1972 b) considered it valid, and reported males and females parasitizing penguins. Finally, Garbin et al.

Comment: Cited by Parona (1900) as Ascaris spiculigera Rudolphi, 1809. There is much confusion in the literature about the many species of Contracaecum. Hartwich (1964) revised this genus and presented a list of synonyms. Among them, considered Contracaecum spiculigera (Rudolphi, 1809) and A. spiculigera synonymous of C. microcephalum. Also, he studied other specimens identified by Rudolphi (1809) as A. spiculigera, but considered these specimens as members of Contracaecum rudolphii Hartwich, 1964. Host: Larus dominicanus.
