1. Males.............................................................................................. 2
- Females............................................................................................. 5
2(1). Patellar apophysis with one peg seta much larger than others (Figs 1–2, 5–7). Proximal arm of tegular apophysis with tip rounded, swollen, lip–like (Figs 3–4, 8–9).................................................. chauliodous Bennett
- Patellar peg setae not exactly as above; one peg seta only slightly, if at all, larger than others (Figs 22, 25) or isolated in a proximal medial position (Figs 34, 44, 47). Proximal arm of tegular apophysis sharply or bluntly pointed (Figs 23–24, 26, 35, 45, 48)................................................................................................. 3
3(2). Distal arm of tegular apophysis with angular, truncated tip (Figs 33, 35–36); proximal arm of tegular apophysis with tip sharply acuminate in ventral view (Figs 33, 35), angular in retrolateral view (Fig 36); posterior margin of proximal arm strongly concave in ventral view (Figs 33, 35)........................................................... somesbar Bennett
- Distal arm of tegular apophysis with rounded tip (Figs 23, 45); proximal arm of tegular apophysis (Figs 23–24, 26, 45, 48) with tip sharply (Figs 45, 48) or bluntly acuminate (Figs 23, 26) in ventral view, but not angular in retrolateral view; in ventral view posterior margin of proximal arm angular (Figs 45, 48) or only weakly concave (Figs 23, 26)......................... 4
4(3). Tip of patellar apophysis relatively smoothly curved with peg setae scattered about dorsal surface, not grouped (Figs 22, 25). In ventral view tip of proximal arm of tegular apophysis bluntly acuminate, posterior margin of proximal arm weakly concave (Figs 23, 26)................................................................... septatus Chamberlin & Ivie
- Tip of patellar apophysis pointed, peg setae usually in distinct groups with a group of three at tip (Figs 44, 47). In ventral view tip of proximal arm of tegular apophysis sharply acuminate, posterior margin of proximal arm angular (Figs 45, 48)..................................................................................... … viator Bennett spec. nov.
5(1). Atrial openings visible in dorsal view (Figs 12, 15).......................................... chauliodous Bennett
- In dorsal view atrial openings usually obscured by vulval ducts (Figs 21, 32, 39, 42)................................. 6
6(5). Atrial openings very small, inconspicuous; parenthesis-like or shepherd’s crook-shaped (Figs 37, 40)................... 7
- Atrial openings much larger (but may be inconspicuous), slit-like or crook-shaped (Figs 16–19, 27).................... 8
7(6). Spermathecal stalks long, convoluted (Figs 41–42)............................................. somesbar Bennett
- Stalks short, nearly linear (Fig. 38)….................................................. viator Bennett spec. nov.
8(6). Spermathecal stalks very short, heads in close proximity to Bennett’s glands (Figs 20–21)…..... lockeae Bennett spec. nov.
- Stalks relatively long, heads well separated from Bennett’s glands (Figs 29, 32)…............ septatus Chamberlin & Ivie
