Raoiella macfarlanei


Pritchard and Baker

Key characters

  • setae c1, d1, e1 weakly to obviously spatulate (Figs. 1, 2, 3)
  • seta h1 subequal in length to h2 (usually inserted ventrally) (Fig. 4)
  • seta h2 weakly spatulate (could be misinterpreted as blunt if in lateral view) (Fig. 4)
  • seta f2 longer than f3 (Fig. 5)
  • coxae III-IV with one seta (3b, 4b)
  • femur II with 4 setae (d, l', bv", v')
  • genua I-II with 3 setae (d, l', l")
  • tarsus I with companion seta obviously longer than solenidion (Figs. 6, 7)
  • tarsus II with companion seta obviously shorter than solenidion (Fig. 7)
  • dorsal setae on tibiae I-II with spatulate tip (Figs. 7, 8)
  • palp tibiotarsus with one solenidion and one tapered, setiform eupathidium distally (Fig. 9), and one seta dorsally
  • setae ps1 and ps2 inserted adjacent to each other
  • male with moderately long ps1 setae (Fig. 10)
  • larva with short h2 setae (Fig. 11)

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.




Olive (Oleaceae)


This species is currently being redescribed by Beard et al.

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).
