Resumo: Abstract: he Brazilian Pampa is predominantly composed of native grasslands with riparian and thickets forest formations, with rich and little known biodiversity of fauna, flora and fungi. The objective of this study was to report phytoseiid species associated with Asteraceae plants from eight physiographic regions of the Pampa biome. Collections were carried out seasonally from November 2021 to August 2022. In each physiographic region, ten species of Asteraceae were collected, totalling 320 samples. Data analysis was mainly based on the relationship between mite and plant. A total of 228 mite specimens of Phytoseiidae were found, represented by 26 species within 12 genera and three subfamilies. Two new species, Amblyseius senecinis n. sp. and Typhlodromus (Anthoseius) bacchariae n. sp. are described and a key to species from the arizonicus group is provided. The most abundant species were Typhlodromalus aripo De Leon, followed by Euseius inouei (Ehara & Moraes), Phytoseius guianensis De Leon, Typhlodromus (Anthoseius) bacchariae n. sp. Neoseiulus californicus (McGregor), N. tunus (De Leon) and Metaseiulus (Metaseiulus) eiko (El-Banhawy).
