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.

Species with hindwings completely black

Zanna tenebrosa (Fabricius, 1775) (including as a synonym Zanna madagascarensis, sometimes treated as a distinct species)

Well, Zanna madagascarensis isn’t a synonym of Zanna tenebrosa, as per FLOW.

Great - thanks heaps

Oops! I rechecked and it is now f. Madagascarensis.

Additional notes:

Zanna orientalis Lallemand, 1959 appears to be a mistranscription of Zanna orientalis Lallemand, 1956, which is a synonym of Saiva transversolineata of Borneo. I remove it from the list of African species

Zanna capensis of South Africa, original description and figures

After removing Zanna orientailis, you should change the number of species from 25 to 24.

Are they illustrations of Zanna pauliani on the web? I am not talking about iNat.

Thanks, text updated from 25->24

There is an illustration of Zanna pauliani included in the original description, but it is not great:

I haven't seen any specimens

Can you give me the translation?

פורסם על-ידי aaravmishra לפני בערך 1 שנים

update: I've added specimen photos of Zanna ascendens, beieri, and capensis, from the Museum für Naturkunde Berlin, bringing the total number of African species represented to 17/24

For translating documents I recommend using Google Lens, which has built-in translation. It is not perfect but it is good enough most of the time

@tonyrebelo @jaheymans @johanheyns @robert_taylor @wolfachim @tuli @moira_fitzpatrick you may find this journal post interesting !

I am working on creating something more organized and useful (hopefully) as I obtain photos for the rest of the species and work through the literature, but hopefully this journal post is a decent starting point:)
