Key to the West African species of Cylindera (Ifasina)

Taking into account the identification key for the western subgenus Ifasina African species given by Serrano (2007), we present an updated key including the new species:

1. Elytral markings without humeral spot; apical lunule reduced to a spot near the outer apical angle....... C. genofiae Rivalier

- Elytral markings with a humeral spot, apical lunule near the apical margin........................................ 2

2. The transversal middle band slightly directed anteriad......................................................... 3

- The transversal middle band perpendicular to the suture or slightly directed posteriad.............................. 4

3. Pronotum slightly rectangular sub-parallel withdrawn at the anterior angles; apex of median lobe slightly bent downward (lat- eral view) and narrowly triangular (ventral view)..................................... C. lutaria (Guérin-Méneville)

- Pronotum quadrangular or even slightly trapezoidal; apex of median lobe slightly bent upward (lateral view) and largely trian- gular (ventral view).................................................................... .. C. agualusai sp. n.

4. Elytral markings with two connected discal anterior dots, apical lunule reaching the suture near the apical tooth; pronotum withdrawn at the anterior and posterior angles, more or less rounded at sides.................. .. C. octoguttata (Fabricius)

- Elytral markings with one discal anterior dot, apical lunule not reaching the suture................................. 5

5. Elytra domed in the middle region of the second third; proepisterna pilose only at the inner region; mandibles extensively more darkened and metallic................................................................. C. decellei Basilewsky

- Elytra not domed; proepisterna pilose at the entire surface; mandibles almost entirely testaceous, darkened at the apex of teeth.................................................................................. C. gulbenkiana Serrano
