Abstract
Examination of 251 samples, collected mainly on cultivated plants, weeds in New South Wales between 1924 and 1980, led to the identification of 25 species of Tetranychidae belonging to 9 different genera. Five of the species are reported from the Australian continent for the first time, these are Aplonobia citri Meyer-Smith (from citrus and peach), Schizotetranychus celarius (Banks), Oligonychus grypus Baker & Pritchard (on sugarcane), O. tiwakae Gutierrez (on the grass Imperata cylindrica) and Tetranychus lombardinii Baker & Pritchard. Five others, already known from Australia, are reported from New South Wales for the first time, these include Eotetranychus lomandrae Davis, O. brevipodus (Targ.), O. ununguis (Jacobi) and Tetranychus neocaledonicus Andre. In addition, in the genus Bryobia, misidentifications are corrected for B. rubrioculus (Scheuten), B. praetiosa Koch s.s. and B. cristata (Duges).
