Holotype. Male (specimen CT-577 figured), New South Wales, Jerusalem Falls near Karuah (about 32°39'S, 151°57'E), 6 Dec 1988, G. Theischinger ( NMV, T-20913). GoogleMaps

Diagnosis. Hydrobiosella gurara can be separated from other species in the group by the absence of lateral subapical hooks on segment X and from H. unispina by the absence of a dorsal spine on segment X.

Description. Wings similar to those of H. arcuata (fig. 1), length of forewing: male 6.5 mm.

Male. Segment IX with a deep notch on mesodistal margin (fig. 7). Segment X with robust mesal lobe, broadbased, with a pair of pigmented lateral lobes, without hooks (figs 5–6); in dorsal view subtriangular, tapered slightly distally with a rounded apex (fig. 5). Phallus robust (fig. 6). Inferior appendages in lateral view, with basal segment subquadrate, length about 1.5 times maximum width; harpago longer than basal segment, length about 1.3–1.4 times length basal segment, slender, length about 5.5 times width, narrowed and weakly (obtusely) angled near middle, slightly dilated in apical third (fig. 6).

Female. Unknown.

Etymology. Gurara — Australian Aboriginal (New South Wales) word for ‘long’ or ‘tall’ (harpago on inferior appendages).

Remarks. The holotype male is the only specimen of Hydrobiosella gurara collected from the type locality in central-eastern New South Wales (latitude 32°39'S).
