Mites of the family Winterschmidtiidae (Acari: Sarcoptiformes: Astigmatina) from agricultural habitats in Brazil, with description of a new species and a key to species reported

The family Winterschmidtiidae is subdivided into four subfamilies; representatives of two are associated wit h insects and those of other two commonly inhabit decaying materials, fungi, plant leaves, vertebrate nests an d stored food. Species of this family are frequently collected during surveys of arboreal acarofauna in Brazil, but in most cases, they are identified up to the generic level. The present work reports winterschmidtiid specie s collected in agricultural environments in Brazil: a new species, Oulenziella longiseta sp.nov., and fou r previously known species, Acalvolia squamata (Oudemans), Oulenzia arboricola (Oudemans), Oulenziell a bakeri (Hughes) and Czenspinskia transversostriata (Oudemans). Among these, A. squamata, O. arboricola and O. bakeri are new records for Brazil.
