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.(AU)

A new species of Sulcana (Hemiptera: Cicadellidae: Gyponini) from the Brazilian Atlantic Forest

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.

On the sharpshooter Versigonalia (Hemiptera: Cicadellidae: Cicadellini): Versigonalia lentiginosa nom. nov., redescription of V. vermiculata comb. nov., and key to species of the genus

Syntypes of Tettigonia vermiculata Signoret, 1855 were studied and redescribed, including the first description and illustration of the male and female genitalia of this species. Based on this study, this Brazilian species, previously placed in Molomea (Proconiini), is herein transferred to Versigonalia (Cicadellini). This transfer resulted in a secondary homonymy and its junior homonym from Argentina, Versigonalia vermiculata Young, 1977 is considered invalid. Thus, we propose a new name, V. lentiginosa nom. nov., for the latter. A taxonomic key to all three species of Versigonalia is also given.(AU)

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.

A new species of Portanus (Hemiptera, Cicadellidae, Xestocephalinae) from Brazil / Uma nova espécie de Portanus (Hemiptera, Cicadellidae, Xestocephalinae) do Brasil

ortanus Ball, 1932 comprises 45 species that occur in Brazil, including Portanus felixi sp. nov. described and illustrated herein. The genus is close to Paraportanus Carvalho & Cavichioli, 2009 and can be distinguished from it by having a transversal groove on the basal third of the subgenital plates. The new species can be distinguished from the other species of the genus by the characters of male genitalia, especially by the pygofer with the apical process pointed, sclerotized and dorso-ventrally directed; and by the aedeagus with apodeme on the basal third.(AU)

O gênero está relacionado a Paraportanus Carvalho & Cavichioli, 2009 e pode ser diferenciado deste por apresentar um sulco transverso no terço basal das placas subgenitais. A nova espécie pode ser distinguida das demais do gênero principalmente pelos caracteres da genitália masculina, especialmente o pigóforo, que apresenta um processo apical pontiagudo, esclerotizado e direcionado dorsoventralmente; e pelo edeago, com apódema no terço basal da haste.(AU)

Aglaenita (Hemiptera: Cicadellidae: Neocoelidiinae): a new species from Brazil

Aglaenita Spinola, 1850 comprises fourteen species, all occurring in Brazil, including a new species, A. hambletoni sp. nov., which is described herein. The genus is close to Biza Walker, 1858 and Megacoelidia Kramer & Linnavuori, 1959. Aglaenita hambletoni sp. nov. can be distinguished from other Aglaenita species mainly by the characters of male genitalia, especially by the pygofer bearing an apical bifurcated process, the branches of the process pointed and sclerotized, the upper branch longer than the lower, tooth-like one; and by the aedeagus without processes and with the ventral margin without teeth. The diagnosis of the genus and the known geographical distribution of its species are also given

Amostragem de cigarrinhas (hemiptera, cicadellidae) através de armadilhas de moericke em cafeeiro arábica

ABSTRACT This study had for objective to evaluate the population fluctuations of the leafhoppers (Hemiptera, Cicadellidae) associated to Coffea arabica in Cravinhos, São Paulo, Brazil. The leafhoppers were sampled weekly by using 60 Moericke trap in the period of April/2005 to April/2006. Were collected 3.243 leafhoppers belonging to eight species: Bahita infuscata, Coelidiana diminuta, Dilobopterus costalimai, Docalidia bifurcata, Joruma (Joruma) sp., Labocurtidia sp., Oncometopia facialis and Scaphytopius irrorellus. The mostly frequency of the leafhoppers associated at coffee crop occurred in the rainy season; all the species of Cicadellidae collected were constants and the Moericke traps located at the median third of the plants were preferred for the capture of this group of insects. D. costalimai presented positive and significant correlations (p 0.05) with the rainfall and maximum and minimum temperatures and O. fascialis was only with minimum temperature.

RESUMO Este estudo teve por objetivo avaliar o padrão de variação populacional de cigarrinhas (Hemiptera, Cicadellidae) associadas ao cafeeiro, em Cravinhos, SP. As amostragens foram realizadas, semanalmente, no período de abril de 2005 a abril de 2006 através de 60 armadilhas de Moericke instaladas nos terços médio e inferior das plantas. Foram coletados 3.243 exemplares de cigarrinhas pertencentes a 8 espécies: Bahita infuscata, Coelidiana diminuta, Dilobopterus costalimai, Docalidia bifurcata, Joruma (Joruma) sp., Labocurtidia sp., Oncometopia facialis e Scaphytopius irrorellus. As maiores abundâncias destes cicadelídeos associados à cultura do cafeeiro ocorreram no período chuvoso; as espécies de cicadelídeos coletadas foram constantes e as armadilhas de Moericke instaladas no terço médio das plantas foram mais eficientes para a captura deste grupo de insetos. Verificou-se correlação positiva significativa entre os valores populacionais de D. costalimai com a pluviosidade e as temperaturas máxima e mínima e, para O. facialis, foi apenas com a temperatura mínima.
