(Modified from Levi & Levi 1962)

1. Opisthosoma straight in lateral view, with median or posterior humps (Fig. 8 D–F)............................ Episinus

- Opisthosoma inclined or vertical in lateral view, with humps on anterior, median or posterior position, on all three positions, or missing (Figs. 8 A–C, 9A–D, 10A–D)...................................................................... 2

2. Eyes in dorsal view in two parallel rows (Saaristo 2006, figs. 45–47)........................................ Moneta
