Previous records in Rio Grande do Sul. Capitão (Ferla et al., 2005); Bento Gonçalves and Encruzilhada do Sul (Johann et al., 2009); Bento Gonçalves (Klock et al., 2011); Bento Gonçalves, Encruzilhada do Sul, Dois Lajeados and Boqueirão do Leão (Ferla et al., 2011); Ilópolis (Marchetti & Ferla, 2011); Venâncio Aires and Roca Sales (Eichelberger et al., 2011); Arvorezinha, Encantado and Taquari (Horn et al., 2011).
Comments. Measurements of our specimens are similar to those in the original description (De Leon, 1965). This species has been reported on citrus, yerba mate and grapevine in Rio Grande do Sul state (Ferla et al., 2005; Ferla et al., 2011). Euseius species are the most common on native vegetation in that state (Ferla & Moraes, 2002).
