Abstract

Seven black-bellied plovers, Squatarola squatarola (L.), from British Columbia and Quebec, and six spotted sandpipers, Actitis macularia (L.), from British Columbia harbored a total of nine species of nematodes. Squatarola squatarola yielded Sciadiocara umbellifera (Molin, 1860), Ancyracanthopsis coronata (Molin, 1860), Viktorocara shejkini Guschanskaya, 1950, Desmidocercella numidica (Seurat, 1920), and Capillaria contorla (Creplin, 1829). Actitis macularia harbored Sciadiocara denticulata n. sp., Ancyracanthopsis coronata, Streptocara c. crassicauda (Creplin, 1829), Capillaria (?) totani (von Linstow, 1875), and a third-stage (?) Skrjabinocerca sp. Sciadiocara denticulata n. sp. is smaller and noticeably more delicate than S. umbellifera; its cephalic lappets are narrow and bear a fringe of minute teeth, and it has an elaborate left spicular apex. Sciadiocara umbellifera and V. shejkini are reported for the first time from North America, and D. numidica (syn. Desmidocerca nudicauda Mawson, 1957) for the first time in a charadriiform bird.
