Diagnosis (reproduced from Bayer 2012): Males with complex conductor and embulus: Conductor with pointed distal ending(s) and numerous small or very small, short spines or tubercles ( Figs 12 View FIGURE 12 , 13 View FIGURE 13 A, 15; Bayer 2012, figs 52a–b, 54a–b, 56a–b, 61a–b, 66a); Embolus always with distinct base containing either ridges ( Bayer 2012, fig. 66c) and/or serrated margins ( Bayer 2012, figs 56b, 62b) and/or very small tubercles ( Bayer 2012, fig. 52c, 54b–c).

In females, median septum generally longer than broad ( Bayer 2012, figs 53a, 62a) (alternatively almost as long as broad, Bayer 2012, fig. 55e); copulatory ducts long and with bulbous ( Bayer 2012, figs 53b, 63b, 64b) and/ or twisted ( Figs 14 View FIGURE 14 B, 16B; Bayer 2012, figs 55f, 59b) sections.
