Key to the genera of Spintharinae

(Modified from Levi & Levi 1962)

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

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

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

3. Posterior median eyes close to laterals (closer to laterals than with each other) (Fig. 6C, D) ................... Stemmops

- Posterior median eyes far from laterals (closer between each other than with respect to laterals) (Fig. 6A, B)............4

4. Opisthosoma higher than wide (in lateral view) (Levi & Levi 1962, fig. 212).............................. Thwaitesia
