Campbell( NMV, T- 21437).  Diagnosis. Males of  Hydrobiosella jibboorcan 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.

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); in lateral view tapered slightly in basal two thirds, slightly bulbous sub-apically with a small dorsal ‘raised ridge’ ( Fig. 12). Phallus generally tube-like, robust, with a pair of narrowly separated sub-apical spines, with two more spines basally ( Figs 11, 12). 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).  Female.
