Six species of birds of the family Sternidae are often found on the southern coast of South America. Sterna trudeaui, S. hirundinacea, Thalasseus maximus, T. acuflavidus and Sternula superciliaris are South American residents and Sterna hirundo, a Nearctic migrant. At least 500 species of nasal mites have been described around the world, and Rhinonyssidae is the most diverse family. These mites are bloodsucking endoparasites that inhabit the respiratory system of birds. This study aimed to report on occurrences of nasal mites in Sternidae on the southern coast of Brazil. Of the 106 birds analyzed, 8.5% (9 birds) were parasitized by nasal mites. This report provides the first record in the Neotropical region for two mite species, Sternostoma boydi and Larinyssus orbicularis parasitizing Thalasseus acuflavidus and Sternula superciliaris. No nasal mites were found in Sterna trudeaui or Thalasseus maximus. One host individual (T. acuflavidus) was parasitized by two species of nasal mites, S. boydi and L. orbicularis.
燕鸥科的六种鸟类经常在南美洲的南部海岸被发现。特鲁udeaui燕鸥、纯色燕鸥、大凤头燕鸥、黄嘴河燕鸥和白眉燕鸥是南美洲的留鸟，而普通燕鸥是新北界的候鸟。全世界已描述的鼻螨种类至少有500种，其中鼻刺螨科是种类最多的科。这些螨虫是吸血内寄生虫，寄生于鸟类的呼吸系统。本研究旨在报告巴西南部海岸燕鸥科鸟类鼻螨的感染情况。在分析的106只鸟类中，8.5%（9只）被鼻螨寄生。本报告首次记录了新热带地区两种螨虫，博伊德鼻刺螨和圆形拉氏螨分别寄生于黄嘴河燕鸥和白眉燕鸥。在特鲁udeaui燕鸥或大凤头燕鸥中未发现鼻螨。一只宿主个体（黄嘴河燕鸥）被两种鼻螨，即博伊德鼻刺螨和圆形拉氏螨寄生。
