ABSTRACT The genus Lepronyssoides Fonseca comprises four Neotropical species associated mainly with rodents. One of these species, L. pereirai (Fonseca), has been recorded parasitizing rodents and marsupials in several states of the north, northeast, and central-west regions of Brazil. This study is based on samples housed at the Acari Collection of the Butantan Institute (IBSP) and the National Collection of Ectoparasites and Vectors of the Univasf (NCEV-Univasf, Petrolina, PE, Brazil). It includes the first record of L. pereirai for the states of Piauí, Mato Grosso do Sul, and new host-associations with Thrichomys pachyurus, T. laurentius and Oecomys cleberi.

关于 Lepronyssoides pereirai (Fonseca, 1935) (Mesostigmata: Macronyssidae) 知识的贡献：宿主和分布

摘要 Lepronyssoides Fonseca 属包括四种主要与啮齿动物相关的新热带物种。其中一个物种 L. pereirai (Fonseca) 已被记录到在巴西北部、东北部和中西部地区的几个州寄生啮齿动物和有袋动物。本研究基于布坦坦研究所 (IBSP) 的螨虫收藏和 Univasf 国家体外寄生虫和载体收藏（NCEV-Univasf，Petrolina，PE，巴西）的样本。它包括皮奥伊州、南马托格罗索州的 L. pereirai 的第一个记录，以及与 Thrichomys pachyurus、T. laurentius 和 Oecomys cleberi 的新宿主关联。
