Die Typen Parasitischer Nematoden in der Helminthen‐Sammlung des Zoologischen Museums in Berlin

Contracaecumovale (Nematoda: Anisakidae) from Rollandia rolland Quoy & Gaimard 1824 (Aves, Podicipedidae) in Argentina

“…The morphology and dimensions of our specimens were concordant with previous reports (CRAM, 1927;MOZGOVOI, 1953;MACKO, 1961;HARTWICH, 1964). Although the complexity of the lips was best discerned by Hartwich (1964), the ultrastructural observations made in the present report showed two small auricles and that the interlabia was one third of the lip height and triangle-shaped, in conformity with this author's findings.…”

“…Fagerholm (1989) considered that the length of the spicules, morphology of the distal end of the spicule and number and distribution of caudal papillae in the males were other good taxonomic criteria. The number and distribution pattern of the caudal papillae agree with those of previous descriptions (CRAM, 1927;HARTWICH, 1964), but the details of the distal end of the spicules at ultrastructural level are described for the first time in the present paper. Macko (1961) and Cram (1927) reported 10 pairs of precloacal papillae, but Hartwich (1964) reported 29-35 pairs of precloacal papillae.…”

Macko (1961) and Cram (1927) reported 10 pairs of precloacal papillae, but Hartwich (1964) reported 29-35 pairs of precloacal papillae. Previous authors reported a wide range of intraspecies variation with regard to the number of precloacal papillae in anisakids: 60-81 pairs in C. osculatum (FAGERHOLM, 1989), 23 -49 in C. ogmorhini (FAGERHOLM;GIBSON, 1987) and 44 -61 in Terranova galeocerdonis (TANZOLA;SARDELLA, 2006).…”

“…Macko (1961) described it in P. griseigena and P. nigricollis from the Czech Republic. The only previous record from the Neotropical region is that of Hartwich (1964) in Podilymbus podiceps in Brazil. Stock and Holmes (1987) cited C. ovale as a member of the parasite communities of P. grisegena, P. nigricollis and P. auritus in Canada.…”
