Diplectrona willandi  sp. nov.

( Figs 14–16View FIGURES 10–16, 24View FIGURES 17–31, 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)GoogleMaps  . Paratypes, Queensland: 2♂, collected with holotypeGoogleMaps  .

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. 24View FIGURES 17–31); hind wings broadly rounded.

Genitalia ( Figs 14–16View FIGURES 10–16, 45–46View FIGURES 32–48): 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. 14View FIGURES 10–16), 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.
