Abstract: Four examined specimens from Brazil, Ceará, with morphological characteristics
belonging to Tibicinini (Hemiptera: Cicadidae) revealed an undescribed genus and
species. Gibbocicada brasiliana gen. et sp. nov., representing the first record
of Tibicinini in Brazil, is recognized mainly for the head three times shorter
than pronotoum in dorsal view, the lateral ocelli almost reaching the anterior
margin of pronotum, the pronotum and mesonotum pronounced dorsally in lateral
view, and the fore wings with the median and cubitus anterior veins rising from
the same point in the basal cell. A key to the genera of Tibicinini is
presented.
