Abstract Pinndorama dilatata sp. nov. is described based on specimens from Amazonas State, Brazil. The genus is firstly recorded from the Brazilian states of Amazonas, Goiás, Maranhão, and São Paulo and a distribution map is provided, including new records to P. dianae, P. guartela, P. melanocephala, P. ronurensis, and P. pitanga. The key to males is updated to include the new species and minor improvements. sp nov State Brazil Goiás Maranhão provided P dianae guartela melanocephala ronurensis pitanga improvements

Abstract Marganana DeLong, 1948 currently includes three species known to occur in the United States, Mexico and Guyana. In this paper, we describe a new species from Brazil - Marganana (Declivana) tetramaculata sp. nov. - which represents the first record of this genus for the country. A revised diagnosis of the subgenus Declivana is provided, along with detailed descriptions and illustrations of males and females of the new species. A key to the four species of Marganana is also provided.

Abstract Neopsis campestris sp. nov. is described and illustrated based on male and female specimens collected on native grassland at the Guartelá State Park, Paraná State, Southern Brazil. New distribution records are presented for three previously known species, Neopsis aurea Takiya & Dietrich, 2017, Neopsis myrceugeniae Takiya & Dietrich, 2017 and Neopsis robusta Linnavuori, 1965, representing the first known records of the subfamily Tartessinae for Paraná State. A distribution map is also provided to illustrate the locality data of specimens studied herein.

Abstract A new leafhopper genus in the tribe Gyponini is proposed based on Magnana splendida gen. nov. et sp. nov., from the state of Rio de Janeiro, Brazil. Representatives of the new genus differ from other genera in the tribe mainly by the large body size, the narrow head, moderately produced anterad, the rugose crown and frons, the ventral surface of metatarsomere I with two double rows of setae, and the aedeagus bearing atrial processes. Detailed descriptions and illustrations are provided, as well as remarks on the morphology of other gyponine genera.

ABSTRACT. Two new species of Polana (Hobemanella) Mckamey, 2006 are described and illustrated from Brazil: Polana (H.) alvarengai sp. nov., from the states of Mato Grosso, Rondônia and Pará, which can be recognized by the aedeagal shaft with subapical group of eight spine-like processes on each side of shaft, on ventral surface; and Polana (H.) arcana sp. nov., from the state of Paraná, which can be recognized by the aedeagus with pair of elongated processes arising at base, almost as long as shaft length and parallel to shaft. A key to the 19 known species of Polana (Hobemanella) is presented.

ABSTRACT Sulcana cunicula sp. nov. is described and illustrated based on four specimens from municipality of São José dos Pinhais, state of Paraná, Brazil. This species can be distinguished from others in the genus by the following characters: (1) head produced, slightly shorter than median length of pronotum; (2) aedeagus bearing a pair of acute ventral processes at mid-length of shaft and extended dorsally. A new record to Sulcana brevis DeLong & Freytag and a key to the three species of the genus are also presented.

Gypona (Marganalana) masamunesp. nov. is described and illustrated based on specimens from Brazil, state of Paraná. This species can be distinguished from the others of the genus by the following combination of characters: 1) connective with stalk apex oriented anteriorly; 2) style, in lateral view, L-shaped and broader subapically; apex tapered and acute; 3) aedeagus slender, curved dorsally, with long and slender processes arising on each side of shaft near the base, as long as aedeagus shaft; shaft without apical processes. A key to the six subgenera of Gypona is provided.

Arapona furcata sp. nov. is described and illustrated based on a male specimen from Peru, department of Madre de Dios. This species can be recognized by the following features: 1) styles without a concavity on the ventral margin; 2) aedeagus robust and with a pair of long and slender preatrial processes; and 3) aedeagus with two apical processes, each with a sharp and hook-like apex. A key to the three known species of the genus is added.
