Abstract
Portanini Linnavuori, 1959 is a small tribe of neotropical leafhoppers that includes two genera: Portanus Ball, 1932 and Metacephalus DeLong & Martinson, 1973. Herein, a checklist of portanines from Peru is given, including several new species records for the country, elevating the known diversity from nine to 22 species. In addition, four species have their department ranges expanded in Peru. Two new portanine species are also described: Metacephalus mamaquilla sp. nov. and Portanus tambopata sp. nov. both from Tambopata National Reserve, Madre de Dios, Peru and we make available habitus photos of other Portanini species from this reserve.
