Two new species of Platypona DeLong (Hemiptera: Cicadellidae: Iassinae: Gyponini) from Peru and key to the species of the genus

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.

Placoscopana, a new genus of Neocoelidiinae (Hemiptera: Cicadellidae) from Ecuador

A new genus of Neocoelidiinae, Placoscopana gen. nov. is proposed and its type-species Placoscopana nigrilinea sp. nov. is described and illustrated based on a male specimen from Ecuador (Orellana Province). Placoscopana gen. nov. is very similar externally to Coronalidia Marques-Costa & Cavichioli, 2007, but differs mainly by the male genitalia: pygopher short with posterior margin approximately truncated; subgenital plates, in dorsal view, with a tuft of setae at apex; and aedeagus with two parallel ventral rows of small spines on the apical half of the shaft.

Two new species of Polana (Hemiptera: Cicadellidae: Iassinae: Gyponini) and redescription of Polana (Striapona) desela

Two new species of Polana DeLong, 1942 are described and illustrated, P. (Angusana) pilosa sp. nov. from Peru and P. (Declivella) maculosa sp. nov. from Brazil. Polana (Striapona) desela Delong, 1979 is redescribed; the female terminalia of this species are described and illustrated for the first time.

Three new species of Peruvian Nelidina (Hemiptera: Cicadellidae: Neocoelidiinae) with key to males

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.

Two new species of Tetralidia Marques-Costa & Cavichioli (Hemiptera: Cicadellidae: Neocoelidiinae) from Peru with a key to species of the genus

Two new species of Tetralidia Marques-Costa & Cavichioli, 2008: Tetralidia pachamama sp. nov. and Tetralidia viracocha sp. nov. are described and illustrated. T. pachamama sp. nov. can be distinguished from the other species of the genus by the simple aedeagus, without processes, spines or lamellae, while T. viracocha sp. nov. can be distinguished by the aedeagus with two pairs of lamellae at shaft and anal tube with basiventral processes strongly curved posteriorly. An identification key to males of the species is provided.
