RESUMO
Xylella fastidiosa Wells et al. is a xylem-borne bacterium that causes some of the most important plant diseases to woody plants such as citrus, olives, almonds and other cultures. This pathogen is mainly transmitted by sharpshooters, among which the tribe Cicadellini (Cicadellinae) includes the largest number of proven vectors. The correct identification of the vectors, along with biological and phenological information, are necessary to identify the key vectors involved in the spread of the bacterium and, consequently, establish control strategies and evaluate risks at a local or regional scale. However, lack of information on the Cicadellini from Argentina has delayed the implementation of control measures. Based on surveys conducted in the main citrus producing areas along with bibliographic data, this contribution provides the first list of Cicadellini species from Argentina that are potential vectors of X. fastidiosa; an identification key to these sharpshooters is provided. Twelve species were recorded from northeastern citrus groves, while from northwestern orchards, with previous information totally absent, 10 species were recorded. Eight species are shared by all producing regions, and five of them are proven vectors of X. fastidiosa (Bucephalogonia xanthophis (Berg), Dilobopterus costalimai Young, Macugonalia cavifrons (Stål), M. leucomelas (Walker), Sonesimia grossa (Signoret)). This contribution provides 22 new insect-plant relationships, information on their natural enemies, the geographic distribution of all species is broadened and the female genitalia of three proven vectors are described for the first time.

Eight new Brazilian species of the South American sharpshooter genus Fonsecaiulus Young, 1977 are described and illustrated. Three new species are from Minas Gerais State (F. youngi sp. nov., F. spinosus sp. nov., and F. unciformis sp. nov.), two from Paraná State (F. chelatus sp. nov. and F. takiyae sp. nov.), one from Paraná and Rio Grande do Sul states (F. truncatus sp. nov.), one from Maranhão State (F. longiramus sp. nov.), and one is recorded only from "Brazil" (F. alvarengai sp. nov.). The species descriptions are focused on the male and female terminalia. With the addition of these new taxa, Fonsecaiulus now comprises 17 species; a dichotomic key to males of all these species is provided. New distribution records are given for the following species: F. cognatus (Schmidt, 1928)-Paraná State, F. rectangularis Felix et al., 2015-Bahia State, and F. sanguineovittata (Signoret, 1855)-Paraguay, Canindeyú Department. Notes on the morphology and distribution of the genus are added.

Two new species of Paratubana Young, 1977 are described and illustrated from Rio de Janeiro state, southeastern Brazil, based on specimens collected in alpine fields (above 1,800 m) of the Serra dos rgos mountain range. Paratubana auromarginata sp. nov. (Pico da Calednia) can be recognized by the paraphyses with the apex bifurcate, forming an outer subquadrate projection and inner spiniform process, whereas in P. takiyae sp. nov. (Parque Nacional da Serra dos rgos) the paraphyses have a pair of strong spiniform processes directed dorsally and crossing each other. The two new species are apparently closely related to each other and both use Eryngium L. (Apiaceae) as host plants. A key to males of the ten known species of the genus is added, as well as two maps of their known distribution.

The sharpshooter genus Balacha Melichar, 1926 has seven recognized species and is distributed in southern South America (Argentina, Brazil, Paraguay, and Uruguay). Here, two new Brazilian species of this genus are described and illustrated, one (B. ancora sp. nov.) from Serra do Caraça and Serra do Cipó (Minas Gerais State) and another (B. nigroflava sp. nov.) from Ponta Grossa (Paraná State) and Passo Fundo (Rio Grande do Sul State). Based on 67 morphological characters, we carried out a parsimony analysis to estimate the phylogenetic position of the two new species. Using implied weighting in TNT, a single topology within Balacha was obtained with k values that varied from 1.599 to 7.412. In this topology, the two new taxa appeared within the clade of black Balacha species. A biogeographical analysis (S-DIVA) suggested that the ancestral area of distribution of Balacha was the Atlantic Forest domain. Balacha species were so far known to have only Eryngium (Apiaceae) species as host plants. Here we report a new host plant for the genus: B. ancora sp. nov. specimens were collected on Actinocephalus polyanthus (Eriocaulaceae). Balacha similis and B. rubripennis are newly recorded from Argentina and specimens of the latter have a very distinct color pattern from the typical Brazilian specimens. Finally, a key to species and maps showing the known distribution of the genus are given (several state records of species are also provided).

The Brazilian species of Mitrapsylla, a Neotropical genus of jumping plant-lice, are reviewed. Twenty-seven species are described as new, and one species originally described from Panama is recorded for the first time from Brazil. This brings the number of Brazilian species from 12 to 40 and for the Neotropical region to 51. The new species are illustrated and Mitrapsylla ceplaciensis (White Hodkinson), M. cubana Crawford and M. itaparica (Crawford) are redescribed. A key for the identification of males is provided for the Brazilian species and information is given on host-plants, habitat and distribution. Host-plants, all Leguminosae, are confirmed for 15 of the new species. The genus is predominantly tropical but extends into the subtropical states in South Brazil.

The genus Aguana Melichar, 1926 previously included only two species from the Atlantic Forest of Southeastern Brazil. Here we provide a revised diagnosis for the genus and describe two new Brazilian species and the female of A. imbricata (Signoret, 1854). The new taxa are A. picinguaba sp. nov. (states of Rio de Janeiro, São Paulo, and Santa Catarina) and A. spitzi sp. nov. (State of São Paulo). Aguana species are very similar to one another externally and can be distinguished mainly by features of the male terminalia (especially of the aedeagus) and female sternite VII. A key to males and females of the genus is added (except the female of A. russata Young, 1977).

Three new Brazilian species of the sharpshooter genus Amblyscarta Stål, 1869 are described and illustrated: A. elianeae sp. nov. (states of Paraná and Minas Gerais), A. souzalopesi sp. nov. (State of Rio de Janeiro), and A. pinna sp. nov. (State of Mato Grosso). The first two species are from the Atlantic Forest, whereas the third is from the Amazon Forest. Cicada unifasciata Fabricius, 1803 is redescribed and transferred to Amblyscarta based on specimens from Guyana and northern Brazil (Amazon Forest). This Fabrician species is the type of the monobasic genus Strictogonia Melichar, 1926, which is thus considered a junior synonym of Amblyscarta. A diagnosis of Amblyscarta is added, as well as brief notes on the phenology of A. elianeae. This paper provides the first detailed descriptions and illustrations of the female terminalia of Amblyscarta species.

ABSTRACT The genus Hanshumba Young, 1977 is recorded from Southeastern and Southern Brazil (Atlantic Forest) and currently includes only three species. Here we describe and illustrate, based mainly on features of the male terminalia, two new species from State of Espírito Santo, Municipality of Santa Teresa: H. setifera sp. nov. and H. teresa sp. nov. The former can be distinguished by the male pygofer and anal tube with large processes bearing numerous setae and the aedeagus with pair of dentiform processes on median portion, whereas the latter has three pairs of longitudinal flanges on the aedeagal shaft. A key to males of the genus is added and its taxonomic status is briefly discussed.
RESUMO
A new species of the sharpshooter genus Juliaca Melichar, 1926, J. nigra sp. nov., from Southeastern Brazil (State of Espírito Santo) is described based on specimens collected on a coffee plantation. In addition, J. sertigerula (Jacobi, 1905), an Andean species, and Tettigonia xanthogramma Signoret, 1854, from Southeastern Brazil (states of Minas Gerais and Rio de Janeiro), are redescribed. The former species was not adequately illustrated and the latter was not treated in the most recent monograph on the Cicadellini. The identity of T. xanthogramma is elucidated and it is transferred to Juliaca (J. xanthogramma comb. nov.).
