Figures 74–76, 124

Material examined. Holotype. Male , Qld , Girraween National Park, nr Wyberba, 10 Oct 1973, A. Neboiss ( NMV T-18518).

Moulds; ( NMV) ; 16 males, 4 females, Terania Creek , N of Lismore, 28°25'S 153°18'E, 21 Jan 1986, G. Theischinger ( NMV) GoogleMaps ; 6 males, female, Wilson River , NW of Wauchope, 31°14'S 152°34'E, 30 Oct 1981, Wells and Carter ( NMV) GoogleMaps .

Diagnosis. Wings uniformly fuscous to mottled; forewing without footstalk on fork 1. In male genitalia, tergite X covered with short setae and shallowly cleft apically; inferior appendages elongate and straight to slightly curved in lateral view.

Description. Spurs 1, 2, 2. Male forewing length 6.6–8.6 mm. Wings rounded apically, hair along veins long, downy in appearance, forewing fork 1 sessile or with a very short footstalk; t1 more distal than t2 and t3 which are almost contiguous, all three crossveins marked by darkened membrane. Male genitalia, Figs 74–76. Segment IX with lateral cleft, preanal appendages small, rounded, widely separated. Segment X robust and setate, cordate but with apex cleft. Inferior appendages stout, in ventral view separated basally, rounded apically, uniformly stout along length; in lateral view slender, apically obliquely truncate. Phallus short, rounded in ventral view, in lateral view down-turned distally.

Distribution. Eastern NSW, and south-eastern and far northern Qld (Fig. 124).

Remarks. The unusual, hairy segment X may represent the medial process of segment X such as is seen in O. aduncata or O. minasata , but expanded. A similar plate is seen in O. cepaforma , but that species has setae only distally, and is not cleft apically.

Etymology. Latin, curta — short, for the phallus.
