Thirty-two specimens of Columbina picui (picui ground-dove) were examined, and a collection of arthropods was made by washing the external surface of the body and the nasal cavity. The species in the order Phthiraptera found and their respective prevalences, mean abundance and mean intensity were: Columbicola passerinae (84.4%; 10.3; 12.2), Hohorstiella passerinae (21.9%; 0.7; 3.1) and Physconelloides eurysema (3.1%; 0.1; 2). The gamasid mites found in the birds and their respective prevalences, mean abundance and mean intensity were: Pellonyssus marui (31.3%; 1.2; 3.9), Ornithonyssus bursa (15.6%; 0.2. ;1.2) and Mesonyssus sp. (6.3%; 0.1; 1). Columbicola passerinae, H. passerinae, P. eurysema, O. bursa, P. marui and Mesonyssus sp. were recorded for the first time infecting C. picui in Brazil. Except for O. bursa, the other species are reported for the first time in the state of Rio Grande do Sul, Brazil.
Foram examinados 32 espécimes de Columbina picui (rolinha-picui), sendo que a coleta de artrópodes foi realizada por meio de lavagem da superfície externa do corpo e da cavidade nasal. As espécies da ordem Phthiraptera encontradas e suas respectivas prevalências, abundância média e intensidade média foram: Columbicola passerinae (84,4%; 10,3; 12,2), Hohorstiella passerinae (21,9%; 0,7; 3,1) e Physconelloides eurysema (3,1%; 0,1; 2). Os ácaros Gamasida encontrados nas aves e suas respectivas prevalências, abundância média e intensidade média foram: Pellonyssus marui (31,3%; 1,2; 3,9), Ornithonyssus bursa (15,6%; 0,2; 1,2) e Mesonyssus sp. (6,3%; 0,1; 1). Columbicola passerinae, H. passerinae, P. eurysema, O. bursa, P. marui e Mesonyssus sp. são relatados pela primeira vez parasitando C. picui no Brasil. Exceto O. bursa, as demais espécies são relatadas pela primera vez no estado do Rio Grande do Sul, Brasil.

With the aim of identifying the species of nasal mites of Paroaria coronata (red-crested cardinal), the nasal cavity of 40 birds were examined. The nasal mites were identified as Ptilonyssus sairae de Castro and Sternostoma pirangae Pence, with 50 percent and 7.5 percent of prevalence, respectively. This is the first record of these mite species parasitizing P. coronata. This report also amplifies the area of occurrence of S. pirangae for Brazil and that of P. sairae for Rio Grande do Sul, Brazil.
