Key to the Afrotropical species of Cladoctonus

1. Elytral interstriae 2 on declivity smooth, other interstriae with sharp granules ( South Africa)........ Cladoctonus natalensis

- All declivital interstriae similar, with sharp granules.......................................................... 2

2. Strial punctures on the elytra larger than those on pronotum, irregularly placed, barely discernible in rows; interstrial setae very fine and hair-like ( Ethiopia to South Africa)................................................. Cladoctonus affinis

- Strial punctures as small or smaller than those on pronotum, mainly in uniseriate rows; interstrial setae bristle-like........ 3

3. Interstrial punctures on elytra of the same size and similarly spaced as those in striae; elytral declivity dull, apex very slightly extended into a lip ( Ivory Coast).......................................................... Cladoctonus similis

- Interstrial punctures slightly smaller and more widely spaced than those in striae; elytral declivity shiny, apex obtuse...... 4

4. Scutellar shield with long golden setae (only female known, frons with long tuft of setae from vertex to epistoma; Kenya, Tanzania).......................................................................... Cladoctonus amanicus

- Scutellar shield smooth (only male known, frons punctate, shiny, with scattered setae; Democratic Republic of the Congo)..................................................................................... Cladoctonus elongatus
