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 the type species P. argentata Wehr, 1933; male is smaller with smaller spicules and 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 not inflated at the anterior region. This genus is reported for the first time in the kelp gull and from Argentina.
