TARSONEMIDAE Canestrini & Fanzago

Origin of the specimens examined: Cerradão: Hymenaea sp., IV-2004 (1); Lecythes sp., VI-2004 (1); Myrtaceae sp.1, III-2004 (2), IV-2004 (1), V-2004 (3); Myrtaceae sp.2, IV-2004 (1); Qualea sp., III-2004 (4); Riparian Forest: B. longifolia, III-2004 (2), I-2005 (1); Byrsonima sp., III-2004 (1); D. furfuraceae, III-2004 (1).

Remarks: This species was the most abundant tarsonemid found on plants of the Myrtaceae family in the Cerrado of São Paulo State in the survey carried out by Lofego & Moraes (2006). DeLeon (1956) and Lofego et al. (2005) suggested that this species is phytophagous. However, Suski (1967) could not exclude the possibility that it also feeds on lichen and fungi.
