Petrobia (Tetranychina) harti (Ewing, 1909)

The oxalis spider mite, P. (Tetranychina) harti , appears to be common and widespread on the mainland, associated mainly with different Oxalis species , but also with Pennisetum longistylum, Citrus grandis and strawberries Fragaria (spp.) ( Carmona 1970 ; Carmona and

Dias 1980), being also common on weeds in greenhouses ( Pina et al. 2012). The INIAV collection contains several specimens, mostly collected from Oxalis corniculata but also from Digitaria sanguinalis , which is a new host for this mite ( Table 1). The oxalis spider mite is also reported from Madeira Island, O on. pes-caprae ( Carmona, 1973a) .
