Diagnosis. Hydrobiosella woonoongoora can be separated from other species in the group by small differences in segment X; the mesal lobe in has a slightly bulbous apex and the lateral lobes have apical hooks directed outwards.

Description. Head, body and wings brownish, some specimens paler. Wings similar to those of H.arcuata (fig. 1), length of forewing: male 6.4–8.1 mm, female 6.6–8.2 mm. Forewing fork 2 long, length fork 2 about 1.6 times length of fork 1; length fork 3 about 1.9 times length footstalk; fork 4 length about 4.6–5.4 times length footstalk. Hind wing fork 1 with very short footstalk; fork 3 length about twice length of footstalk.

Male. Segment IX with small shallow notch medially on distal margin (fig. 31). Segment X with mesal lobe slightly bulbous apically, with a pair of short hairs/bristles subapically, in lateral view not downturned distally (fig. 30); in dorsal view, narrowed slightly subapically (fig. 29), with a pair of pigmented lateral lobes, which terminate in small, outward projecting hooks (figs 29–30). Inferior appendages in lateral view, with basal segment length about twice width, broad basally, rounded distally; harpago more slender, with ventral margin sharply angled at about 90 degrees near middle, very slightly dilated in apical third (fig. 30).

Female. Genitalia typical of genus, with a small, rounded projection on sternite VIII mesodistally (figs 46–47).

Etymology. Woonoongoora — Australian Aboriginal word for the Lamington National Park ranges (type locality — Lamington National Park).

Remarks. Many male and female specimens of Hydrobiosella woonoongoora have been collected from five sites near the type locality in northeastern New South Wales and southeastern Queensland (latitudinal range 27°35'– 28°15'S).
