Metatergal tubercles in 8-10 irregular transverse rows, mostly without setae; metatergal setae short with slightly flared tips; lateralmost two rows of tubercles not enlarged, together forming narrow pseudo-paranotum with 6 marginal tubercles. Male leg 6 coxa with small, rounded, mediodistal projection. Telopodite (Fig. 6A) with pp straight; at in longitudinal plane, short and rounded-triangular; dp directed laterobasally at base; mab concave medially, deeply divided with smaller medial lobe bent posteriorly, tapering and with sharp subterminal tooth on lateral surface; larger, lateral mab lobe widening to thickened, emarginate apex; meb curving strongly behind mab, divided at ca one-third length into 2 thin processes.

A and D are uncoated specimens; scale bars = 0.1 mm. Note two mites on Agathodesmus adelphus sp. n. telopodites.

Distribution.

Known only from rainforest high on Mt Bartle Frere in tropical north Queensland (Fig. 13A). Possibly co-occurs on Mt Bartle Frere with Agathodesmus quintanus sp. n. and Agathodesmus summus sp. n., although both these species are found at higher elevations on the mountain.

Name.

Latin adelphus, 'brother', a punning reference to the 'Frere' in the name of the type locality; adjective.

Remarks.

Fig. 6A shows two unidentified mites, one on each telopodite. They have not been removed from the holotype.
