Key to the genera of Spintharinae

(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

- Eyes in dorsal view with a different arrangement (procurved or recurved) ( Fig. 6 A–D)............................... 3

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

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

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

- Opisthosoma longer than wide (in lateral view).............................................................. 5

5. Carapace flat and almost circular in outline (in dorsal view) (Levi 1954b, figs. 46,47)....................... Spintharus

- Carapace convex, sometimes highest in thoracic region, subtriangular in outline (in dorsal view) (Levi 1954a, figs. 10, 11, 19– 25)........................................................................................ Chrosiothes
