( Figs 14–16 , 24 , 45–46) Material examined. Holotype ♂ , N Queensland , Fishery Falls , 17°11'S 145°52'E , 10–11.xi.2007 , A. Cairns , A. Wells , W. Cairns ( NMV ) . Paratypes , Queensland : 2♂ , collected with holotype . Diagnosis. Resembling D. spinata and D. inermis , but lacking discrete spines associated with the phallus; however, it has the endothecal apical angles on the phallic apparatus acute rather than rounded, and sclerotised and spiny in appearance, although visible only in the macerated specimen; in ventral view the phallic apparatus is stout and heavily sclerotised; the lateral margins of tergite X are similarly heavily sclerotised. Description. Male. Length of each forewing: 5.2–5.5 mm (n = 3); cell ac shallow, but not parallel-sided ( Fig. 24 ); hind wings broadly rounded. Genitalia ( Figs 14–16 , 45–46 ): Sternite IX shallowly concave, tergites IX and X partially fused, lateral margins darkly sclerotised; gonopods slender, elongate, length of coxopodite about 7x maximum width, harpago about 0.3x length of coxopodite, strongly curved mesally, a small mesal spur at base; phallic apparatus stout, heavily sclerotised ventrally (indicated by shaded area in Fig. 14 ), endotheca apical angles acute, sclerotised. Female. Unknown. Distribution. Known only from the type locality in a water catchment reserve just south of Tully in the wet tropics of north-eastern Queensland . Remarks. The head warts of this species differ from those of others in the genus, being wide and shallow.
