Phytoseiidae (Acari: Mesostigmata) of the subfamily Amblyseiinae from Brazil.

Phytoseiidae is composed of essentially predatory mites most commonly found on the aerial plant parts. Presently, it is considered to contain about 2,650 valid species, divided into nearly 102 genera of three subfamilies: Amblyseiinae, Phytoseiinae and Typhlodrominae. Approximately 250 of those have been reported from Brazil.

A new species of Thyreophagus (Acari: Acaridae) from Brazil, with notes on species associated with stored food and human habitats and a key to species of this genus.

A new species Thyreophagus cracentiseta n. sp. is described morphologically based on adult females, adult homeomorphic and heteromorphic males collected from chicken feed in Brazil.

A new genus and species of phytoseiid mite (Acari: phytoseiidae) from the Brazilian Atlantic Forest.

Phytoseiidae (Acari: Mesostigmata) from natural ecosystems in the State of São Paulo, Brazil.

This work describes the results of a study of the phytoseiid mites collected from plants in two natural ecosystems in the State of São Paulo, Brazil-Cerrado and Atlantic Forest. In this study, 40 phytoseiid species are reported. Measurements of different structures are given for species for which measurements for the respective São Paulo populations were not previously provided.
