Abstract
Two new species of Eustigmaeus, E. piracicabensis Paktinat-Saeij & Bagheri sp. nov., and E. oliveirai Paktinat-Saeij & Bagheri sp. nov., are described based on females collected from soil, humus and moss in the São Paulo state, Brazil. Also, a key to the American Eustigmaeus species is provided.
