sp. nov.

Diplectrona willandi sp. nov.

( Figs 14–16 View FIGURES 10–16 , 24 View 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 holotype GoogleMaps .

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

Genitalia ( Figs 14–16 View FIGURES 10–16 , 45–46 View 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. 14 View 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.
