Two new species of Sundarion (Hemiptera: Membracidae: Darninae) and taxonomic notes on two congeneric taxa

Two new species of Sundarion Kirkaldy, 1904 - Sundarion flavopiceum sp. nov. (from Brazil, state of Pará, Serra Norte) and Sundarion marmoratum sp. nov. (from French Guiana, Montagne des Chevaux) - are described. The first species differs from S. flavum (Fairmaire, 1846) in having smaller supra-humeral horns, and being dark brown with a large yellow spot on each side of the posterior process. In this aspect, it resembles Alcmeone picea (Fairmaire, 1846). The second species is similar to S. flavum except for being variegate yellowish-brown. Taxonomic comments are provided for S. notabile Souza & Rothéa, 2005, which was previously known only from males, and for S. compressicornis (Fairmaire, 1846) comb. nov., originally described in Hemiptycha Germar, 1833 and latter transferred to Hemikyptha Metcalf, 1927. New geographical distribution records are provided for both species.

Alcmeone robustus (Hemiptera: Membracidae: Darninae): description of the last-instar nymph and biological notes

The last-instar nymph of Alcmeone robustus (Butler, 1877) (Membracidae, Darninae, Darnini) is described and illustrated, and some biological and behavioral notes are provided. The nymphs were observed on Pera sp. (Euphorbiaceae) in the locality of Jacareí, state of São Paulo, Brazil, until they became adults. The newly emerged adults, male and female, are also briefly re-described.

Duas espécies novas de membracídeos (Hemiptera, Membracidae) da Mata Atlântica do Estado de São Paulo, Brasil

Two species are described: one belonging to the genus Antonae Stål (Smiliinae, Ceresini), Antonae brasiliensis sp. nov., and another to Hypheodana Metcalf (Darninae-Darnini), Hypheodana gargionei sp. nov., both from Campos do Jordão, São Paulo. The genus Antonae Stål is recorded for the first time in Brazil, and Hypheodana, on the other hand, in the Atlantic Forest.
