Previous records in Rio Grande do Sul.

Comments. Setae Z1 and St IV were about 30 and 20% shorter than in the original description, and setae Z5 25% longer than in the description (De Leon, 1967). This was the most common predator on associated plants present around strawberry crops (Ferla et al., 2007). It has also been reported on other cultivated plants as well as on natural vegetation, in combination with other mite species (Moraes & McMurtry, 1983; Moraes et al., 1990; Noronha et al., 1997).
