Contracaecum sp. Host: Fulica leucoptera. SI: intestine. Lo: Trelew, Chubut Province. Reference: Parona (1900). 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.
