Remarks
This species is placed in the wandoo species group proposed by Beard et al. (2018).
This species was collected from an unidentified immature Eucalyptus tree, in the south west corner of Western Australia.
Raoiella karri grouped with R. todtiana as species 2 in Dowling et al. (2012); and was listed as undescribed species in Ochoa et al. (2011).
