The African species of Eurystylus are revised and their status as pests of important agricultural crops is reviewed. A key is provided for the 12 recognized species, one of which, E. lestoni, is described as new. A diagnosis and description are provided for each species, as well as illustrations of diagnostic taxonomic characters and information on host-plant associations and distribution. Lectotype designations are made for eight nominal species of Eurystylus and two species are removed from the genus. The following new synonymies are established: E. annulipes (Poppius)= E. annulipes impunctatus (Poppius), syn. n.; E. bellevoyei (Reuter)= E. parvulus(Reuter), syn. n., E. occidentals Wagner, syn. n., E. gallouedeci Villiers, syn. n. and E. argenticeps Odhiambo, syn. n.; E. lineaticollis Poppius=E. pallidiventris Poppius, syn. n. and E. mutabilis Bergoth, syn. n.; E. oldi Poppius=E. kivuensis Schouteden, syn. n., E. risbeci Schouteden, syn. n., E. phaiopterus Odhiambo, syn. n., E. immaculatus Odhiambo, syn. n. and E. bilqis Linnavuori & Al-Safadi, syn. n. Two species are removed from the genus Eurystylus(E. sobrius (Walker)= Plesiocapsus sobrius (Walker), comb. n. and E. sericeus (Walker)=Proboscidocoris sericeus (Walker), comb. n.) and one species, E. rufocunealis Poppius, is assigned the status of nomen dubium.
