Holotype. Male (specimen CT-611 figured). Victoria, Mt Buller, headwaters Chalet Ck , 1400 m (about 37°10'S, 146°25'E), 19 Mar. 1993, I. Campbell ( NMV, T- 21437). GoogleMaps

Diagnosis. Males of Hydrobiosella jibboor can be separated from those of other species in the group by the dorsal ‘raised ridge’ sub-apically on segment X and rounded apex and segment IX with almost straight distal margin.

Description. Wings similar to those of H. bandabanda ( Fig. 1 View Figures 1–7 ), length of forewing: male 6.9 mm.

Male. Segment IX with a weak notch in meso-ventral margin ( Fig. 13 View Figures 8–16 ), and with an almost straight distal margin ( Fig. 12 View Figures 8–16 ). Segment X in dorsal view, a ‘tongue-shaped’ process, with almost parallel sides in basal third, with a pair of very small knobs baso-laterally, tapered distally to a rounded apex, length about 2.3 times width, without a central dorsal ridge or groove ( Fig. 11 View Figures 8–16 ); in lateral view tapered slightly in basal two thirds, slightly bulbous sub-apically with a small dorsal ‘raised ridge’ ( Fig. 12 View Figures 8–16 ). Phallus generally tube-like, robust, with a pair of narrowly separated sub-apical spines, with two more spines basally ( Figs 11, 12 View Figures 8–16 ). Inferior appendages in lateral view, robust, with basal segment sub-rectangular, length about twice maximum width; harpago shorter, length about half length basal segment, length about 1.6–1.7 times maximum width, with broad rounded apex ( Fig. 12 View Figures 8–16 ).
