A new species of the sharpshooter genus Cardioscarta (Hemiptera: Cicadellidae) from Bolivia and Peru Rev. Bras. Zool.
Cavichioli,Rodney Ramiro; Mejdalani,Gabriel.
ABSTRACT The South American sharpshooter genus Cardioscarta Melichar, 1932 comprises six species. In this paper we describe and illustrate C. splendida sp. nov. based on a specimen from Bolivia (male holotype deposited in DZUP). The new species can be recognized by the orange ground color with five transverse dark brown stripes on dorsum (one on crown and four on forewings), and by the aedeagus with two pairs of dorsal processes on the basal apodemes and a single process at the apex of the shaft. A female from Peru is tentatively assigned to the new species and is also described, since it has the same color pattern as the holotype. An updated key to males and females of all known species of the genus is also given.

Attraction of Bucephalogonia xanthophis (Hemiptera: Cicadellidae) to volatiles of its natural host Vernonia condensata (Asteraceae) Scientia Agricola
Bento,José Maurício Simões; Arab,Alberto; Zacarin,Giuliano Grici; Signoretti,André Gustavo Corrêa; Silva,José Wilson Pereira da.
Plant volatiles are important cues for the orientation of herbivorous insects. It is possible that these compounds indicate whether the plant is suitable for feeding and larval development, or for mating aggregation. Vernonia condensata (Asteraceae) is known to attract species of leafhoppers, most of them important vectors of the citrus variegated chlorosis (CVC). In this study, we evaluated the role of volatiles of V. condensata on the orientation of Bucephalogonia xanthophis (Hemiptera: Cicadellidae). Four-arm olfactometer bioassays showed that only males were attracted to the volatiles of the host-plants Citrus sp. and V. condensata. Furthermore, fresh leaves of V. condensata induced a stronger response than volatiles from hexane-extracted leaves. This...

Azevedo Filho,Wilson Sampaio de; Botton,Marcos; Paladini,Andressa; Carvalho,Gervásio Silva; Ringenberg,Rudiney; Lopes,João Roberto Spotti.
Brochosomes production is considered a feature of Cicadellidae, and may represent an outstanding innovation which has played an important role in the development and diversification of this insect group. The objective of this study was to identify the species of Proconiini that produced egg brochosomes associated with grapevines in the Serra Gaúcha region of Brazil. Egg brochosome characteristics and an identification key are also discussed. The specimens were collected using yellow sticky cards in four vineyards (Vitis vinifera L.) from October 2004 to May 2006. Eight species capable of producing egg brochosomes were identified:Acrogonia citrina Marucci & Cavichioli; Homalodisca ignorata Melichar; Molomea consolida Schröder; Molomea lineiceps...

Notes on Neotropical Proconiini (Insecta: Hemiptera: Cicadellidae). VIII: morphology of the male and female genitalia of Paraulacizes munda, revalidated from synonymy of P. confusa Rev. Bras. Zool.
Mejdalani,Gabriel; Cavichioli,Rodney Ramiro.
ABSTRACT Paraulacizes munda (Fowler, 1899) has been considered a junior synonym of P. confusa (Signoret, 1855). These two species were described from Mexico. Here it is shown that P. munda can be distinguished from P. confusa by the color and size of the body. Hence, the former is revalidated from synonymy of the latter. Descriptions and illustrations of the male and female genitalia of P. munda, which are necessary for an accurate identification of leafhopper species in general, are provided for the first time. Paraulacizes munda can be distinguished from the other 11 species currently included in Paraulacizes by the following combination of features: ground color of anterior dorsum yellow or pale yellow; dorsal processes of male pygofer strongly inflated...

Froza,Joyce A.; Cavichioli,Rodney R.; Costa,Luiz A.A.; Mejdalani,Gabriel.
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.
