Generic descriptions are given by Tillyard (1924: 288); Mosely and Kimmins (1953: 387) and Neboiss (1977: 45).
Key to males of known Australian groups (or ungrouped species) of Hydrobiosella Tillyard (after Cartwright 2010, 2012)
1. Phallus without pair of parameres (Figs 2, 3, 5, 6; Cartwright 2012a, figs 2, 3; Neboiss 1986, figs pp. 99, H. amblyopia; 101, H. tasmanica; 102, H. corinna) 2
- Phallus with pair of parameres (Cartwright 2010, figs 2, 3, 5, 6; Neboiss 1986, figs pp. 99, H. michaelseni, H. waddama; 101, H. letti; 102, H.bispina; 103, H. arcuata) 6
2. Preanal appendages present, usually small (Cartwright2012a, figs 2, 3; Neboiss 1977, figs 204, 205, 216, 217; Neboiss 1986, figs pp. 101, H. tasmanica; 102, H. corinna; Neboiss 2003, figs 8a–h) 3
- Preanal appendages absent (Figs 2, 3, 18, 19; Neboiss 1986, figs pp. 99, H. amblyopia; 101, H. tasmanica) 4
3. Preanal appendages relatively slender, elongate and ‘unattached’ to segment IX (Cartwright 2012a, figs 2, 3, 5); NE-Qld Hydrobiosella eminentia group
- Preanal appendages often short and bulbous or ‘attached’ to segment IX (Neboiss, 1977, figs 204-211; Neboiss 1986, figs p. 102, H. corinna; Neboiss, 2003, figs 8A-H); Tas Hydrobiosella corinna group
4. Phallus apically with downward projecting spine(s) (Neboiss 1977, figs 216-221, 225, 226; Neboiss 1986, figs p. 101, H. armata, H. tasmanica; Neboiss 2003, figs 10A-G, 11A-G, 12A-F); Tas H. tasmanica group
- Phallus apically without downward projecting spine(s) (Figs 2, 3; Neboiss 1982, fig. 12; Neboiss 1986, figs p. 99 H. amblyopia) 5
5. Segment IX with a large disto-lateral projection (Neboiss 1982, fig. 12; Neboiss 1986, figs p. 99 H. amblyopia); S-WA H. amblyopia (ungrouped)

- Inferior appendages with harpago without dark row of setae forming fringe along ventral margin (Figs 18, 19; Neboiss 1986, figs pp. 99, H. michaelseni, H. waddama) 7
7. Parameres elongate and sinusoidal, attached ventrally to base of phallus (Cartwright 2012b, figs 2, 3, 5, 6; Neboiss 1977, fig. 233; Neboiss 1986, figs p. 99, H. waddama); Tas, SE Aust. Hydrobiosella waddama group
