Very preliminary notes on the Zanna of Africa with photos of 17 species

Zanna is a genus of large planthoppers found throughout Africa and Asia. In Africa, Zanna is the most commonly encountered genus of Fulgorids (and will probably remain so until the genus is inevitably removed from the family Fulgoridae). 24 species are known from Africa, but the genus is in major need of a modern revision. In absence of that, the images here from the entomology collection at the NHM London are meant to present an introduction to the genus in Africa and its complexities, but are not meant to be diagnostic. Only 17/24 species are pictured, and other factors such as the shape of the cephalic process in lateral view, the range, and the characters detailed in the original descriptions should also be considered when attempting to identify African Zanna, . A key to the genus does not exist, and identification to species level of most Zanna is discouraged until a more complete understanding of the genus can be made.
