A new genus of katydid from the Amazon Rainforest (Orthoptera: Tettigoniidae; Phaneropterinae; Steirodontini): Ninth contribution to the suprageneric organization of the Neotropical phaneropterines

Emsleyfolium diasae n. gen. et n. sp., from the Brazilian, Colombian, Ecuadorian and Peruvian Amazon is described in this contribution. This new genus is morphologically very similar to Stilpnochlora, but is distinguished from the other Steirodiontini genera by its cone-head (similar to some genera of subfamily Conocephalinae, e.g. Neoconocephalus and Bucrates), modification of the tenth tergite into three lobes and absence of styles on subgenital plate. Thanatosis behavior is described as a defense mechanism.

The tribe Dysoniini part IV: New species of Quiva Hebard, 1927 (Orthoptera: Tettigoniidae: Phaneropterinae) from Brazilian rainforest and some clarifications

Two new species of the genus Quiva: Quiva buhrnheimi n. sp. and Quiva gutjahrae n. sp. from Brazilian Amazon are described. Determinations for distributional data previously published by Sovano & Mendes (2013) are clarified and the synonymy of Ituana dorisae under Q. abacata is confirmed. In this paper, an updated key to subgenus Quiva is provided.

Two new genera of predatory katydids (Orthoptera: Tettigoniidae: Meconematinae) from the Amazon rainforest

Meconematinae comprise small predatory katydids. There are currently seven genera and 58 species recorded for the Neotropical region. Two new genera of Phlugidini are described from the Amazon region, Arboraptor gen. nov., type species Arboraptor viridis sp. nov., and Tyrannoraptor gen. nov., type species Tyrannoraptor arboreus (Nickle, 2003) n. comb. A key to the Neotropical genera of Phlugidini is included and we provide a map showing the known distribution plus comments on their behavior observed during fieldwork.

New species and new behavioral data of Phlugiola Karny, 1907 (Orthoptera: Tettigoniidae: Meconematinae) from the Brazilian Amazonian Rainforest

Phlugiola Karny, 1907 is a genus of small predatory katydids with six included species distributed in Brazil, Bolivia, Colombia, Peru and Suriname. In this paper two new Brazilian species are described, Phlugiola longipedes sp. nov. (type locality: Amazonas, Tefé) and Phlugiola igarape sp. nov., (type locality: Acre, Bujari) both from tropical rainforests. Behavioral data and natural history notes are provided.

Description of the female and new characteristics of the male of Phlugis gracila Nickle, 2003 (Orthoptera: Tettigoniidae: Meconematinae) with new behavioral data

A new genus of predatory katydids (Orthoptera: Tettigoniidae: Listroscelidinae) from the Amazonian Rainforest

Most of the predatory katydids Listroscelidini species known were described from the Brazilian Atlantic Forest. Here a new genus and species from the Amazonian Rainforest is described. Based on its morphological characteristics, this new genus represents an intermediate form between two closely related genera, Listroscelis Serville and Monocerophora Walker.

Description of a new species of Lutosa Walker, 1869 (Orthoptera: Anostostomatidae: Lutosinae) from the Brazilian Atlantic Forest, with biological and behavioral information

Lutosa horribilis sp. nov., a new species of Anostostomatidae is described from a Brazilian Atlantic Forest environment. Notes on defensive behavior and diet are also provided.

Description of the male and redescription of the female of Agaurella mirabilis (Brunner von Wattenwyl, 1891) (Orthoptera: Tettigoniidae) with new behavioral data

The description of the male of Agaurella miriabilis is provided as well as the redescription of the female with additional characters. It is recorded for the first time the geographical occurence to Brazil, within the states of Amazonas and Rondônia, and behavioral data.
