The Piauí State, Brazil, has never had its chigger fauna recorded. In this study, we examined chiggers collected on marsupials, rodents, and lizards from the conservation unit Parque Nacional da Serra das Confusões (PNSC). Herein we describe four new species, Paraguacarus klompenin. sp., Neoschoengastia ochoain. sp., Quadraseta welbournin. sp., and Susa bauchanin. sp. Furthermore, an additional seven species are reported: Eutrombicula alfreddugesi (Oudemans, 1910), Microtrombicula brachytrichiaBrennan, 1971, Microtrombicula rhipidomysiGoff, Whitaker and Dietz, 1983, Parascoschoengastia aemulata (Brennan and Jones, 1964), Parasecia validaBrennan, 1969, Pseudochoengastia petrolinensis Jacinavicius, Bassini-Silva and Barros-Battesti 2019, and Quadraseta flochi (Brennan and Jones, 1960). This is the first report of chiggers in Piauí State, which includes one of the most biodiverse areas in the Caatinga biome and is of particular importance to conservation. The genera Paraguacarus Goff and Whitaker, 1984 and Susa Audy and Nadcharam, 1960 are reported here for the first time to Brazil.
巴西皮奥伊州从未有过恙螨动物区系的记录。在这项研究中，我们检查了在保护单位 Serra das Confusões 国家公园（PNSC）的有袋动物、啮齿动物和蜥蜴上采集的恙螨。本文描述了四个新种，即 Paraguacarus klompenin. sp.、Neoschoengastia ochoain. sp.、Quadraseta welbournin. sp. 和 Susa bauchanin. sp. 此外，还报告了另外七个物种：Eutrombicula alfreddugesi (Oudemans, 1910)、Microtrombicula brachytrichia Brennan, 1971、Microtrombicula rhipidomysi Goff, Whitaker and Dietz, 1983、Parascoschoengastia aemulata (Brennan and Jones, 1964)、Parasecia valida Brennan, 1969、Pseudochoengastia petrolinensis Jacinavicius, Bassini-Silva and Barros-Battesti 2019 和 Quadraseta flochi (Brennan and Jones, 1960)。这是皮奥伊州首次报告恙螨，该州是卡廷加生物群落中生物多样性最丰富的地区之一，对保护具有特殊意义。Paraguacarus Goff 和 Whitaker, 1984 和 Susa Audy 和 Nadcharam, 1960 这两个属是巴西首次报道的。
