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 .
