New species of Tyrannoraptor Mendes, Oliveira, Chamorro-Rengifo & Rafael, 2018 (Orthoptera: Tettigoniidae: Meconematinae: Phlugidini) with asymmetrical jaws from the Brazilian Amazon Rainforest.

Tyrannoraptor Mendes, Oliveira, Chamorro-Rengifo & Rafael, 2018 (Tettigoniidae: Meconematinae: Phlugidini) is currently a monotypic genus. The type-species Tyrannoraptor arboreus (Nickle, 2003) is recorded to Peru (Loreto) and Brazil (Amazonas). In this work, we describe the second species of the genus, Tyrannoraptor venator sp. nov., recorded to the Brazilian Amazon rainforest. The new species is described based on a male and three female specimens. A key to species of Tyrannoraptor and a distribution map of the genus are provided as well as comments on the natural history of the new species.

The Austral Predator Katydid-new species of Megatympanon Piza, 1958 (Orthoptera: Tettigoniidae: Listroscelidinae: Terpandrini) from the Brazilian Atlantic Rainforest.

Megatympanon Piza, 1958 (Tettigoniidae: Listroscelidinae: Terpandrini) is presently a monotypic genus and the only Terpandrini occurring in South America. The type-species M. speculatum Piza, 1958 is recorded in the Atlantic Forest biome in southeastern Brazil. In this work, we describe an additional species, Megatympanon austroraptorum sp. nov., the second species of the genus, occurring in the Southern Atlantic Forest biome. The new species is described based only on a single male; the female of the new species is unknown. A distribution map of the genus is provided as well as comments on the natural history of the new species.

New genus of Steirodontini Brunner von Wattenwyl, 1878 (Orthoptera: Tettigoniidae: Phaneropterinae) from the Brazilian Amazon Rainforest.

The tribe Steirodontini (Phaneropterinae: Tettigoniidae) currently comprises five genera and 56 species, with its distribution restricted to the Neotropical region. In Brazil, four genera and 20 species of this tribe are recorded, all with records restricted to the Brazilian Southeast and South regions. This fact is a strong indication that the Brazilian fauna of this group is underestimated. In this work, the new monotypic genus Coronophyllum gen. nov. and the new species Coronophyllum catarinae sp. nov. from Amazonas, Brazil, are described and illustrated. Additionally, a map and comments on its distribution in an endemic area of the Brazilian Amazon are provided.

Insect (Hexapoda) diversity in the oceanic archipelago of Fernando de Noronha, Brazil: updated taxonomic checklist and new records

ABSTRACT Hexapods, commonly known as insects, are a neglected taxonomic group in the Fernando de Noronha archipelago, with unanswered questions about their species richness and the ecological processes in which they are involved (e.g., colonization, introduction, establishment, and extinction). Herein, we provide an updated Hexapod checklist with current nomenclatural combinations. The entomofauna of the Fernando de Noronha archipelago is currently composed of 453 species in 21 orders. The orders, and their respective number of species, are: Blattaria (9), Coleoptera (118), Collembola (29), Dermaptera (3), Diplura (1), Diptera (134), Embioptera (1), Hemiptera (29), Hymenoptera (59), Isoptera (2), Lepidoptera (25), Mantodea (1), Neuroptera (3), Odonata (5), Orthoptera (11), Phasmatodea (1), Phthiraptera (6), Psocoptera (3), Siphonaptera (1), Thysanoptera (10), and Zygentoma (2). The archipelago has 263 new taxon records (family + genera + species). Thirty-eight species (3.39%) were described from local specimens and most of them are likely endemic species. This study more than doubles our knowledge (from the previous 190 records) of the entomofauna in this large Brazilian archipelago. This study also provides a baseline for studies on its conservation status and for implementing future environmental management programs.

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.

Studies on Brazilian Pseudophasmatidae (Phasmatodea) with the description of a new species of Agrostia Redtenbacher and new records for Metriophasma Uvarov and Parastratocles Redtenbacher

ABSTRACT Pseudophasmatidae currently includes 65 species recorded from Brazil. In this paper, we increase this number to 68 species by describing Agrostia flavimaculata sp. nov., based on male and female specimens from Acre and Amazonas states. Furthermore, Parastratocles multilineatus (Rehn) and Metriophasma (Metriophasma) diocles (Westwood) are recorded for the first time from Brazil based on specimens from Rondônia, Acre and Amazonas states. A key to species of Agrostia is also given.

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.

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.

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 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.

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.
