- Pregonite with bifid or bifurcate apex and with 0–2 setulae on posterior surface; distiphallus without posterior spines, vesica variable............................................................................................ 8

8. Vesica, in anterior view, with apex covered by two membranous lobes............................................ 9

- Vesica, in anterior view, with a single membranous lobe...................................................... 10
