Abstract New records and distributional notes of Chironomidae (Insecta, Diptera) are provided for four protected areas in the state of Pernambuco, northeastern Brazil. Additionally, we also present new records and update of distributional ranges from Brazil and the Neotropical Region. In total, 810 specimens belonging to 35 genera within the subfamilies Chironominae (22 taxa), Tanypodinae (11 taxa) and Orthocladiinae (2 taxa) were found. The subfamilies Chironominae and Tanypodinae predominated. Axarus Roback, 1980 and the Tanytarsus ortoni-group were recorded for the first time in the state of Pernambuco, while Nanocladius Kieffer, 1913a was recorded for the first time in the Northeast Region of Brazil. Our results make evident how much and where current knowledge of the northeastern Brazil chironomids remains fragmentary.

来自巴西伯南布哥州四个保护区的摇蚊科（昆虫纲：双翅目）

摘要 为巴西东北部伯南布哥州的四个保护区提供了摇蚊科（昆虫纲、双翅目）的新记录和分布说明。此外，我们还提供了巴西和新热带地区分布范围的新记录和更新。总共发现了属于摇蚊亚科 (22 个分类群)、Tanypodinae (11 个分类群) 和 Orthocladiinae (2 个分类群) 中 35 个属的 810 个标本。亚科 Chironominae 和 Tanypodinae 占主导地位。Axarus Roback, 1980 和 Tanytarsus ortoni-group 在伯南布哥州首次被记录，而 Nanocladius Kieffer, 1913a 在巴西东北地区首次被记录。我们的研究结果表明，目前对巴西东北部摇蚊的了解在多少和哪些地方仍然不完整。
