ABSTRACT The last instar nymph of Talipes appendiculatus (Fonseca) is described and illustrated, and biological data are given on the immatures and adults. The 5th instar nymph has the body covered with tuberculate chalazae; head and thorax without scoli; abdomen with terga III-VIII with single dorsal scoli, all different in size, III and VIII small, V the largest about 2x longer than wide. Descriptions of the adults (male and female) are also provided, with the addition of some new characters. The species (adults, immatures of various stages) has been collected on branches of Cassia fistula L. (Leguminosae: Caesalpinioidea), and is frequently attended by bees and wasps.

ABSTRACT 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.

Enchenopa luizae sp. nov. (holotype female from Brazil, State of São Paulo, municipality of São José dos Campos, Parque Natural Municipal Augusto Ruschi at 23°04'05°S", 45°56'22"W, 06.VIII.2011, R. La Rosa leg. deposited in DZUP) is described and diagnosed from the Atlantic Forest Vale do Paraíba, São Paulo, Brazil. The new species is very similar to Enchenopa monoceros (Germar, 1821) in overall aspects but much larger and with inconspicuous lateral secondary carinae. The fourth instar nymph is also briefly characterized.

A new species of Oeda Amyot & Serville, 1843 - Oeda (Oeda) mielkei sp. nov. from Peru, Madre de Dios, 12°52'S, 71°22'W - is described. It differs from the other species of O. (Oeda) in having the inflated pronotal process more elongate, and amber color; the suprahumeral horns are much more developed, club-shaped, about as long as the width of head, forming an arch with the tips touching each other; the metopidium, in lateral view, is almost vertical above head. A key, including images of all species (except O. mirandai Fonseca) are also provided.

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.

The tribe Talipedini Deitz is redefined and its boundaries are expanded with the inclusion of the following taxa: Erechtia Walker, 1858 (formerly placed in Membracini), Pseuderechtia gen. nov. (type species: Leioscyta neivai Fonseca, 1941), and Talipes Deitz, 1975 gen. reval. (formerly junior synonym of Trinarea Goding, 1926, the latter herein considered new synonym of Erechtia). Along with these taxonomic rearrangements, some nomenclatural changes are also introduced. The species treated in this paper are: Erechtia gibbosa (DeGeer, 1773), E. carinata (Funkhouser, 1922) comb. nov., E. cristalta sp. nov. (type locality: French Guyana, Saül), E. diminuta sp. nov.

Due to the inclusion of Erechtia in Talipedini, Tropidoscyta Stål, 1869 is reinstated (in Membracini), and 24 species previously included in Erechtia are considered as incertae sedis within Membracini. A key to genera and new distribution records of the treated taxa are also provided.
