notes
Xue, Han & Zhang (2015a) have redescribed this species, based on material from scotch broom. They stress that gall mites generally are confined to a much narrower range of host plants than is listed above. In that connection it is relevant that they described a new species, viz. Aceria davidmansoni, narrowly related to A. genistae and earlier confused with that species, that causes growth disturbances of the shoots in Ulex europaeus, common gorse. Admittedly from New Zealand, but common gorse has been introduced in New Zealand from Europe. See also Han, Hong & Zhang (2016a).
