Similar species
Raoiella macfarlanei is similar morphologically to Raoiella eugeniae.
Raoiella macfarlanei: opisthosomal setae f2 68-79; setae f3 31-33; setae d on femora I-II are longer than setae d on genua I-II; palp eupathidium not divided distally.
Raoiella eugeniae: opisthosomal setae f2 40-56; setae f3 22-33; setae d on femora I-II are subequal in length to setae d on genua I-II; palp eupathidium clearly divided distally.
Distribution
Greece
Hosts
Olive (Oleaceae)
Remarks
This species was redescribed by Beard et al. (2018) and placed in the newly proposed macfarlanei species group.
Reports of R. macfarlanei on mango in India are considered erroneous.
Femora I-II occasionally asymmetrical with 3 or 4 setae present on either side (setae l' absent or present).
