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.

A new genus of Gyponini, Sakakibarana gen. nov., is proposed and its type species S. amazonica sp. nov. is described and illustrated based on specimens from the Amazon Rainforest of Northern Brazil (states of Amazonas and Pará) and French Guiana. The new genus can be distinguished from other members of the Gyponini by the following morphological features: robust body, short crown, crown and face transition distinct and subfoliaceous, pronotum strongly declivous, male pygofer with caudal process, and aedeagus with dorsal apodemes with a pair of processes. A discussion comparing the new genus with the related genus Tenuacia DeLong, 1977 is provided.

Three new South American leafhopper genera of the tribe Gyponini are proposed: Beltrana gen. nov. based on Beltrana reticulata gen. et sp. nov. from French Guiana, Fulana gen. nov. based on Fulana brasiliensis gen. et sp. nov. from Brazil, and Sicrana gen. nov. based on Sicrana plana gen. et sp. nov. from Brazil and Ecuador. Diagnoses, detailed descriptions, and illustrations are provided for each taxon, as well as comparisons with closely related genera. In addition, the following synonyms are proposed: Freytagana DeLong, 1975 as a junior synonym of Marganana DeLong, 1948 and F. gibsoni DeLong, 1975 as a junior synonym of M. (Marganana) mexicana DeLong & Freytag, 1963. Chilella DeLong & Freytag, 1967 is transferred from Gyponini to Selenomorphini Evans, 1974.

The previously monotypic genus Proxima DeLong & Freytag, 1975 is reviewed and new diagnostic characters are added. The type-species Proxima ocellata DeLong & Freytag, 1975 described from the State of Espírito Santo, Brazil, is redescribed and newly recorded from the State of Minas Gerais. Also, two new species are described and illustrated: Proxima nigromaculata sp. nov. from the states of Espírito Santo, Maranhão, Minas Gerais, Rio de Janeiro and Rio Grande do Sul and Proxima meloi sp. nov. from the states of Bahia and Minas Gerais. An identification key to the species of the genus is provided.

Two new species of the previously monotypic genus Platypona DeLong, 1982 from Peru are described and illustrated: P. furcata sp. nov. (Cusco Department) and P. inca sp. nov. (Pasco Department). These two species can be distinguished from each other, as well as from the type-species, P. sinverda DeLong, 1982, mainly by features of the style and aedeagus. A key to the three known species of Platypona is provided.

A new species of Tozzita Kramer, 1964, Tozzita bifida sp. nov., is described and illustrated. The new species can be distinguished from the other species of the genus by the following characteristics: (1) forewing with commissural brown band; (2) pygofer with dentiform process on ventral margin and apex not spatulate; (3) subgenital plates with macrosetae at apex; (4) style with preapical lobe developed and produced posteriorly; (5) aedeagus symmetrical; (6) anal tube with bifid basal process. Tozzita ips Kramer, 1964 is firstly recorded from Brazil. Additionally, an updated genus description and an identification key to males of the species are provided.

Three new species of Nelidina DeLong, 1953 are described and illustrated, N. bifida sp. nov., N. coronata sp. nov. and N. platypenis sp. nov., all from Peru. A key to males of the six known species of Nelidina is presented and a new record for Nelidina sportula Kramer, 1967 is added.
