Previous issue date: 2009-12-23 / Vanellus chilensis is a bird species of the family Charadriidae distributed across Central and South America. Despite its high abundance and broad distribution, there are few records of parasites on this species. Aiming to identify the helminths and arthropods that parasitize V. chilensis in southern Brazil, twenty eight birds were necropsied. For collection of ectoparasites, the birds were individually washed in water containing detergent. After that, they were necropsied and their organs were examined for helminths under a stereomicroscope. The helminths found and its respective prevalence, mean abundance and mean intensity were: Brevithominx asperodorsus (Enoplida, Capilariidae) 53.6%, 4.5 and 8.4; Heterakis psophiae (Oxyurida, Heterakidae) 39.3%, 1.0 and 2.55; Dispharynx nasuta (Spirurida, Acuariidae) 28.6%, 4.11 and 14.38; Echinostoma aphylactum (Echinostomida, Echinostomatidae) 17.9%, 0.64 and 3.6; Stomylotrema vicarium (Plagiorchiida, Stomylotrematidae) 10.7%, 0.25 and 2.33; Neivaia cymbium (Cyclocoeloidea, Cyclocoelidae) 7.1%, 0.14 and 2.0; Gyrocoelia perversa (Cyclophyllidea, Dioecocestidae) 60.7%. The Phthiraptera found were Actornithopilus sp. (Amblycera, Menoponidae) and Quadraceps guimaraesi (Ischnocera, Philopteridae). Another arthropod collected was the nasal mite Rhinonyssus sp. (Acarina, Rhinonyssidae). H. psophiae is cited for the first time parasitizing the order Charadriiformes in RS. B. asperodorsus, E. aphylactum, N. cymbium represent new records for Charadiidae in the State. This is the first report of natural infection in Charadriidae by the parasite S. vicarium in the region of study. The cestode G. perversa and the nematode D. nasuta are cited for the first time parasitizing V. chilensis in RS. The lice Actornithopilus sp. and Quadraceps guimaraesi are new records in RS as parasites of V. chilensis, which is also reported as a new host for the nasal mite Rhinonyssus sp / Vanellus chilensis, quero-quero, tem distribuição na América do Sul e América Central, é uma ave muito comum na região sul do RS. Há poucos relatos a respeito de parasitos nesta espécie, o que incentivou o desenvolvimento deste trabalho. Com o objetivo de conhecer os helmintos e artrópodes que ocorrem em V. chilensis foram examinadas 28 aves, as quais foram lavadas, individualmente, em água com detergente para obtenção dos ectoparasitos e após necropsiadas para a coleta de helmintos. Os helmintos encontrados e respectivas prevalências, abundância média e intensidade média foram Brevithominx asperodorsus (Enoplida, Capilariidae) 53,6%, 4,5 e 8,4; Heterakis psophiae (Oxyurida, Heterakidae) 39,3%, 1,0 e 2,55; Dispharynx nasuta (Spirurida, Acuariidae) 28,6%, 4,11 e 14,38; Echinostoma aphylactum (Echinostomida, Echinostomatidae) 17,9%, 0,64 e 3.6; Stomylotrema vicarium (Plagiorchiida, Stomylotrematidae) 10,7%, 0,25 e 2,33; Neivaia cymbium (Cyclocoeloidea, Cyclocoelidae) 7,1%, 0,14 e 2,0; Gyrocoelia perversa (Cyclophyllidea, Dioecocestidae) 60,7%. Os Phthiraptera encontrados foram Actornithopilus sp. (Amblycera: Menoponidae) e Quadraceps guimaraesi (Ischnocera, Philopteridae), e o ácaro nasal Rhinonyssus sp. (Acarina: Rhinonyssidae). B. asperodorsus, E. aphylactum, N. cymbium, tem seu primeiro registro na família Charadriidae para o RS, H. psophiae tem seu primeiro registro na ordem Charadriiformes para o RS. Este é o primeiro registro de infecção natural por S. vicarium em Charadriidae para o RS. G. perversa e D. nasuta tem seu primeiro registro em V. chilensis no RS.
