1. Males.............................................................................................. 2
- Females............................................................................................. 5
2(1). Patellar apophysis with one peg seta much larger than others ( Figs 1–2 View FIGURES 1–4 , 5–7 View FIGURES 5–9 ).

- Distal arm of tegular apophysis with rounded tip ( Figs 23 View FIGURES 22–24 , 45 View FIGURES 43–46 ); proximal arm of tegular apophysis ( Figs 23–24 View FIGURES 22–24 , 26 View FIGURES 25–26 , 45 View FIGURES 43–46 , 48 View FIGURES 47–48 ) with tip sharply ( Figs 45 View FIGURES 43–46 , 48 View FIGURES 47–48 ) or bluntly acuminate ( Figs 23 View FIGURES 22–24 , 26 View FIGURES 25–26 ) in ventral view, but not angular in retrolateral view; in ventral view posterior margin of proximal arm angular ( Figs 45 View FIGURES 43–46 , 48 View FIGURES 47–48 ) or only weakly concave ( Figs 23 View FIGURES 22–24 , 26 View FIGURES 25–26 )......................... 4
4(3). Tip of patellar apophysis relatively smoothly curved with peg setae scattered about dorsal surface, not grouped ( Figs 22 View FIGURES 22–24 , 25 View FIGURES 25–26 ). In ventral view tip of proximal arm of tegular apophysis bluntly acuminate, posterior margin of proximal arm weakly concave ( Figs 23 View FIGURES 22–24 , 26 View FIGURES 25–26 )................................................................... septatus Chamberlin & Ivie View in CoL
- Tip of patellar apophysis pointed, peg setae usually in distinct groups with a group of three at tip ( Figs 44 View FIGURES 43–46 , 47 View FIGURES 47–48 ). In ventral view tip of proximal arm of tegular apophysis sharply acuminate, posterior margin of proximal arm angular ( Figs 45 View FIGURES 43–46 , 48 View FIGURES 47–48 )..................................................................................... … viator Bennett View in CoL spec. nov.
5(1). Atrial openings visible in dorsal view ( Figs 12, 15 View FIGURES 10–15 ).......................................... chauliodous Bennett View in CoL

6(5). Atrial openings very small, inconspicuous; parenthesis-like or shepherd’s crook-shaped ( Figs 37, 40 View FIGURES 37–42 )................... 7
- Atrial openings much larger (but may be inconspicuous), slit-like or crook-shaped ( Figs 16–19 View FIGURES 16–21 , 27 View FIGURES 27–32 ).................... 8
