Diagnostic description.

Male with head + 19 rings, female with head + 20. Colour in alcohol very pale yellow. Male/female ca 9.0/9.5 mm long; ring 12 maximum diameter ca 0.75/0.9 mm, maximum width ca 0.8/1.0 mm. Metatergal tubercles in 10–12 irregular transverse rows, mainly without setae; metatergal setae short with slightly flared tips; lateralmost tubercles not enlarged, not forming pseudo-paranotum. Male leg 6 without coxal projection. Telopodite (Fig. 11B) with pp slightly curving posteriorly; at in oblique plane (facing posterolaterally), short, narrowly triangular, curving posterolaterally; dp directed laterobasally and slightly posteriorly at base; mab expanded distally, divided into 2 distally rounded lobes, the medial lobe with truncate medial projection at ca midlength; meb curving behind mab and nearly as long, divided at ca midlength into shorter, needle-like lateral process and broad medial process terminating in upturned hook.

Distribution.

Known only from rainforest at the type locality in tropical north Queensland (Fig. 13B). Possibly co-occurs on Mt Bartle Frere with Agathodesmus adelphus sp. n. and Agathodesmus quintanus sp. n.

Name.

Latin summus, 'highest'; adjective. This species was found at the top of Queensland's highest mountain, Mt Bartle Frere.

Remarks.

The Bartle Frere females were assigned to this species rather than to the co-occurring Agathodesmus adelphus sp. n. and Agathodesmus quintanus sp. n. because the females lack the narrow pseudo-paranota found in the other two species.
