Material examined. Holotype ♂, Qld, Mt Bartle Frere, 0.5 km N of South Peak, 6–8.xi.1981, 1500 m, Earthwatch (QM [WTH-0459]).
Paratypes 3♂ (1 dissected), data as for holotype (NMV [PT-999; WTH 0315]).
Diagnosis. This species resembles D. tortula and D. anaplasis in general arrangement of male genitalic structures but is distinguished by the shorter, regularly curved apicolateral processes on abdominal segment IX, and, in ventral view, the stoutly pillar-shaped coxopodites of the gonopods.
Description. Male. Length of each forewing: 8–8.5 mm (n = 4); maxillary palpi with segments 2, 3, and 4 equal in length.
Genitalia (Figs 132–133, 176): Abdominal segment IX clearly differentiated from tergite X, reduced to very narrow strip laterally, and with apicolateral process on each side evenly curved mesad, brush of setae on ventral margin of distal 1/3; in ventral view terminating in acute, setose apex; tergite X in dorsal view shallowly cleft apically; gonopods each with coxopodite stoutly pillar-like, subrectangular in ventral and lateral views, harpago bifid, lobes tapered distally; phallic apparatus without parameres, slender in distal half, stout medially, slightly narrower in proximal half.
Distribution. Known only from the type locality in north-eastern Queensland.
