Key to the genera of Afrotropical Euophryinae (males only)

1. Retromarginal tooth of chelicera with multiple cusps (e.g. Fig. 3)................................................ 2

- Retromarginal tooth of chelicera with one or two cusps (e.g. Figs 8, 19).......................................... 3

2. Several teeth on promargin of chelicerae (Fig. 3)..................................................... Chinophrys

- Two teeth on promargin of chelicerae............................................. Lophostica [Mascarene Islands]

3. Body short and stout, abdomen rounded, as long as wide (Fig. 250)..................................... Yimbulunga

- Other body proportions, abdomen oval, longer than wide...................................................... 4

4. Third leg longer than others, with very dense and long hairs on distal segments... Saitis [African species probably misplaced]

- Third leg not longest, without such modified hairs............................................................ 5

5. Embolus with accompanying free terminal apophysis, appearing as two adjacent structures (Figs 109, 150)....... Rumburak

- Embolus without accompanying terminal apophysis, clearly a single structure, but sometimes with lobes or denticles along its margins............................................................................................. 6

6. Tibial apophysis absent, tiny spiders <2 mm in length (Figs 157, 166)...................................... Tanzania

- Tibial apophysis present, larger spiders> 2 mm in length....................................................... 7

7. Medium sized to large spiders (4–11 mm), carapace quite high, evenly high in anterior half (Fig. 226); embolic spiral large, its diameter larger than half width of bulb, placed parallel to long axis of bulb; tibial apophysis always visible in ventral view of palp......................................................................................... Thyenula

- Small to medium sized spiders (2,5– 5 mm), carapace usually somewhat flattened, sometimes slightly elevated from anterior eyes to midpoint of carapace (Fig. 91); embolic spiral smaller, its diameter less than half width of bulb, placed perpendicular or obliquely to long axis of bulb; if spiral large and placed parallel, then tibial apophysis not visible in ventral view of palp.................................................................................................. Euophrys
