title: Co-occurrence of Pectinospirura argentata Wehr, 1933, Skrjabinoclava andersoni n. sp. and larvae (Nematoda: Acuariidae) in the proventriculus of Larus dominicanus Lichtenstein (Aves: Laridae), with notes on their attachment.
abstract: Pectinospirura argentata Wehr, 1933, Skrjabinoclava andersoni n. sp. and acuariid larvae, collected from the proventriculus of the kelp gull Larus dominicanus from coastal Buenos Aires, Argentina, are described. This is the first record of the genus Pectinospirura Wehr, 1933 from South America and from the kelp gull. The measurements of both sexes are given because there are some differences with previously described specimens of P. argentata; the male is smaller with smaller spicules and the female is larger with smaller eggs. Skrjabinoclava andersoni n. sp. can be distinguished for all other species in the genus by the morphology of both spicules and by the cuticle which is not inflated anteriorly. This genus is reported for the first time in the kelp gull and from Argentina.
