A new species of the planthopper taxon Bennini (Hemiptera: Fulgoromorpha: Cixiidae) was discovered in the wide interstitial voids of a granitic blockfield in Vietnam. A key to the species of the Vietnam-endemic Bennini genus Sanghabenna is provided and Sanghabenna florenciana sp. nov. is described and illustrated. Molecular data including 18S in part and CO1 barcode sequences of the species, as well as for the first time a detailed description of nymphal morphology of a Bennini are provided. According to the ecological parameters of its habitat and its morphological configuration, Sanghabenna florenciana sp. nov. is classified as an exapted eutroglophile taxon.
