Key characters
- setae c1 obviously spatulate; setae d1, e1 with weakly spatulate to broad blunt tips (Fig. 1)
- seta h1 obviously longer than h2 (Fig. 2)
- seta h2 short, with blunt to tapered tip (Fig. 2)
- seta f2 shorter than f3 (Fig. 2)
- coxae III-IV nude
- femur II with 4 setae (d, l', bv", v')
- genua I-II with 2 setae (l', l" present; d absent)
- tarsus I with companion seta obviously longer than solenidion (Fig. 3)
- tarsus II with companion seta subequal or slightly longer than solenidion (make sure its not broken) (Fig. 4)
- dorsal seta on tibiae I-II setiform with tapered tip (can be finely tapered) (Fig. 5)
- palp tibiotarsus with one solenidion and one blunt eupathidium distally (Fig. 6), and one seta dorsally
- setae ps1 and ps2 inserted adjacent to each other (Fig. 7)
- male with short to moderate ps1 setae, 12-14 microns (Fig. 8)
- male femur II same as female
- male genua I-II with 3 setae (d, l', l")
- larva with elongate, filiform setae h2
Similar species
Raoiella davisi is morphologically similar to Raoiella didcota.
Raoiella davisi: dorsal opisthosomal setae c1 > 30 microns; prodorsal setae v2 > 60 microns.
Raoiella didcota: dorsal opisthosomal setae c1 < 25 microns; prodorsal setae v2 < 60 microns.
Distribution
Australia (QLD)
Hosts
Monotoca scoparia (Epacridaceae).
Mites were collected on a species of low shrub, M. scoparia, growing under a Eucalyptus forest in south east Queensland. The recorded host plant is most likely an incidental record. We strongly suspect a species of Eucalyptus to be the true host plant for this species.
Remarks
This species was placed in the australica species group proposed by Beard et al. (2018).
