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.

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.
