Two new species of Hanshumba from Southeastern Brazil and a key to males of the genus (Insecta: Hemiptera: Cicadellidae: Cicadellini)
Provedor de dados: 92
Autores: 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.

Notes on Neotropical Proconiini (Insecta: Hemiptera: Cicadellidae). VIII: morphology of the male and female genitalia of Paraulacizes munda, revalidated from synonymy of P. confusa
Provedor de dados: 103
Autores: 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...

On the identification of two Brazilian leafhoppers: redescription of Scoposcartula frontaliana comb. nov. and description of the female of S. talitae (Hemiptera: Cicadellidae: Cicadellini)
Provedor de dados: 103
Autores: Mejdalani,Gabriel; Carvalho,Rachel Alexandre.
This paper deals with two species of Scoposcartula Young, 1977 that are very similar to each other externally (form and color pattern): S. frontaliana (Metcalf, 1955) comb. nov. (from the state of Bahia, NE. Brazil) and S. talitae Leal, Mejdalani &amp;amp; Cavichioli, 2005 (from the state of Espírito Santo, SE. Brazil). The former species, previously positioned in Amblyscarta Stål, 1869, is redescribed and a male specimen is selected as the lectotype. The previously unknown female of the latter species is described for the first time. Scoposcartula frontaliana can be distinguished from S. talitae by features of the male and female genitalia. The most remarkable difference is in the male pygofer, which has a conspicuously concave posterior margin in S....

A new species of Tipuana (Auchenorrhyncha: Cicadellidae: Cicadellini) from the state of Amazonas, Brazil, with a key to males of the genus
Provedor de dados: 103
Autores: Cavichioli,Rodney Ramiro; Mejdalani,Gabriel.
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.

A new species of the sharpshooter genus Cardioscarta (Hemiptera: Cicadellidae) from Bolivia and Peru
Provedor de dados: 103
Autores: 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.
