| The Neotropical sharpshooter Parasubrasaca felixi, gen. nov., sp. nov., is described and illustrated from the Atlantic Rainforest of Southeastern Brazil (state of Espírito Santo). The new genus can be distinguished from other members of the Cicadellini by several morphological features, including a unique modification of the basal portion of the aedeagus, which bears a conspicuous, ventrally directed projection that articulates with the connective. The projection bears a pair of strong spines directed posteriorly. In addition to the external morphology, color pattern, and male genitalia, the female genitalia of the new taxon are also described in detail. A discussion comparing the new genus with similar Neotropical taxa (Subrasaca Young, 1977, Soosiulus... |

| Aurigoniella meridionalis, sp. nov. is described and illustrated from Morretes and São José dos Pinhais, Paraná State, southern Brazil. It can be easily distinguished from the Aurigoniella type-species, A. dutrai, by its distinct color pattern, smaller size, shorter crown, hindleg knees attaining lateral lobe of pronotum, aedeagus broadest height around mid-length, and paraphyses ramus biramous. |

| ABSTRACT A new species of the genus Dasmeusa Melichar, 1926 is described and illustrated from specimens collected in the State of Amazonas, Northern Brazil. Dasmeusa imperialis sp. nov. can be distinguished from the five known species of the genus, as well as from those of closely related genera, by the following combination of features: dorsum yellow with orange, preapical transverse irregular stripe on forewing; male pygofer moderately produced posteriorly, with posterior margin broadly rounded; style without preapical lobe, narrow and truncate apically; aedeagus with robust apical process directed ventrally, ventral margin of this process dentate; paraphyses with pair of dorsal dentiform projections on stalk, rami slender and directed posterodorsally;... |

| ABSTRACT Onega comprises nine valid species distributed in South American countries, Bolivia, Colombia, Ecuador, Paraguay and Peru, commonly at high altitudes. The genus has as diagnostic characteristics the transition crown-frons with transversal carina; crown and superior portion of frons with concavities; pronotum wider than transocular width of head; and paraphysis, when present, as a median esclerite. The present paper describes Onega musa sp. nov., from Ecuador and Peru, which can be distinguished from other Onega species by: body mostly yellow, with brown maculae distributed on dorsum; posterior margin of male pygofer serrate, with long microsetae on the basiventral margin; aedeagus with shaft bisinuate with dorsal acute preapical process; female... |

| A new species of Tipuana Melichar, 1926, T. similis sp. nov., is described and illustrated based on specimens from the state of Amazonas, northern Brazil. The new taxon is externally very similar to T. chirensis Young, 1977. It can be distinguished from the latter and from the other known species of the genus mainly by the aedeagus with a triangular, posteriorly directed projection between the basidorsal apodemes, and with shaft not expanded apically and bearing two sharp, short apical processes curved dorsally. Diagnostic features of the new species are also found in the paraphysis, which is symmetrical, expanded towards the apex and with a round apical excavation. A key to the species of Tipuana (males) is added. |

| In some American countries, grapevines are affected by Pierce's disease (PD), which is caused by a particular strain of Xylella fastidiosa not yet reported in Brazil. In order to investigate the potential for PD spread in Brazil in case of pathogen introduction, we conducted a faunistic analysis of leafhoppers (Hemiptera: Cicadellidae) associated to vineyards in the State of Rio Grande do Sul, with emphasis in the subfamily Cicadellinae (sharpshooters), which includes the main potential vectors of X. fastidiosa. Leafhopper samplings were carried out fortnightly during two years (9/2004-9/2006) in four Vitis vinifera vineyards in the municipalities of Bento Gonçalves and Farroupilha (RS). Thirtyfour leafhopper and six spittlebug species were collected, but... |

| Foram estudados os aspectos biológicos das cigarrinhas Acrogonia gracilis (Osborn), Dilobopterus costalimai Young e Oncometopia facialis (Signoret) em plantas jovens de laranja Citrus sinensis L. Osbeck em condições controladas de 25±2ºC, 60±10% de umidade relativa e 12h de fotofase. Essas cigarrinhas são vetoras de Xylella fastidiosa Wells em citros. Foram observados cinco ínstares em D. costalimai e O. facialis e seis em A. gracilis. O período médio de duração de ovo a adulto e a longevidade foram, respectivamente, 54,5 e 72,4 dias para A. gracilis, 54,7 e 36,4 dias para D. costalimai e 67,1 e 15,5 dias para O. facialis. |

| Sharpshooter leafhoppers (Hemiptera, Cicadellidae, Cicadellinae) in citrus groves of the area of Bebedouro, SP, with description of a new species of Acrogonia Stål. Sixteen species of Cicadellidae, subfamily Cicadellinae, were collected and identified: 11 of the tribe Cicadellini and five of the tribe Proconiini. The ten most common species, together with a new species, are characterized based on external morphology and male genitalia: Acrogonia citrina Marucci & Cavichioli sp. nov.; Bucephalogonia xanthophis (Berg, 1879); Dilobopterus costalimai Young, 1977; Ferrariana trivittata (Signoret, 1854); Hortensia similis (Walker, 1851); Macugonalia cavifrons (Stål, 1862); M. leucomelas (Walker, 1851); Oncometopia facialis (Signoret, 1854); Plesiommata... |

| Leafhoppers and psyllids species which occur in citrus ecosystem were studied in the Sao Paulo State. The capture was realized with a portable vacuum sampler. Leafhoppers of the Cercopidae, Cicadellidae, Cixiidae, Delphacidae, Derbidae, Flatidae, Fulgoridae, Membracidae, Nogodinidae, and Psyllidae (Hemiptera) family were collected. The main family was Cicadellidae with 58 species of leafhopper collected. In the subfamily Cicadellinae sharpshooters of the Cicadellini and Proconiini tribes were collected, with 17 and five species respectively. The most important sharpshooters/leafhoppers were Plesiommata corniculata Young, Hortesia similis (Walker), Ciminius albolineatus (Taschenberg), Ferrariana trivittata (Signoret), and Sonesimia grossa... |

| The purpose of this study was to analyze sharpshooter fauna in a five-year-old 'Westin' sweet orange orchard. Yellow sticky traps were placed on the edge of a forest, and on the periphery and inside the citrus stand. The traps were evaluated fortnightly, for three years. The most frequent species were Acrogonia citrina Marucci & Cavichioli, Bucephalogonia xanthophis (Berg), and Oncometopia facialis (Signoret). B. xanthophis occurred more in the forest edge, especially on spring and winter. A. citrina occurred most frequently in the forest edge, especially on spring. The highest incidence of O. facialis was inside the citrus stand, on spring and summer. Other cicadellids occurred more often in the forest edge, especially on summer. A. citrina, B.... |

| Four new species, Daedaloscarta erwini sp. nov. (Peru: Loreto), D. maculata sp. nov. (Brazil: Amazonas), D. mene sp. nov. (Ecuador: Orellana), and D. redacta sp. nov. (Brazil: Amazonas) are described and placed in the new genus Daedaloscarta gen. nov. Species of the new genus can be readily distinguished from other Cicadellini genera by their: (1) dark brown to black dorsal coloration with contrasting large ivory spots; (2) crown produced and round anteriorly (Figs 1-8); (3) pronotum narrower than transocular width of head, with lateral margins parallel; (4) male pygofer with pair of acute finger-like processes arising at dorsal margin directed inwardly and ventrally; (5) subgenital plates with apical two-thirds very slender; (6) aedeagus very large with... |

| Xylella fastidiosa Wells et al. é uma bactéria gram-negativa, limitada ao xilema de plantas e responsável por doenças de importância econômica em diversas culturas, como a requeima-da-folha ou atrofia-dos-ramos em cafeeiro. É transmitida por insetos sugadores de xilema e quatro espécies de cigarrinhas já foram descritas como transmissoras do patógeno para cafeeiro. O objetivo deste trabalho foi determinar o grau de infectividade natural por X. fastidiosa em cinco espécies de cigarrinhas Cicadellidae potencialmente transmissoras da bactéria para cafeeiro: Acrogonia citrina Marucci & Cavichioli, Bucephalogonia xanthophis (Berg), Dilobopterus costalimai Young, Oncometopia facialis (Signoret) e Sonesimia grossa (Signoret). As coletas foram realizadas... |
