Discimita linnavuorii, new genus and species (Hemiptera: Heteroptera: Pentatomidae: Pentatominae), is described from the Central African Republic. The genus is superficially similar to representatives of the Neotropical subfamily Discocephalinae, but the labium, which arises anteriad of the imaginary line traversing head at anterior limit of the eyes, exludes such a possibility. The new genus exhibits an unusual mixture of morphological characters that are present in Sciocorini, Triplatygini and Myrocheini, and it is tentatively placed in the tribe Myrocheini.
