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.

A new species of Timnewia García Aldrete (Psocodea: 'Psocoptera': Ptiloneuridae), from Brazil.

A new species of Timnewia from the Brazilian state of Roraima, is here described and illustrated. It differs from T. greeni (New) in details of the forewing and in hypandrium and phallosome morphology.

A new species of Brasineura Silva-Neto & García Aldrete (Psocodea, 'Psocoptera', Ptiloneuridae), with comments on morphological variation in B. troglophilica and a revised generic diagnosis.

Brasineura serranortensis sp. n. is here described and illustrated. This is the third known species of Brasineura and differs from the other species in the genus in phallosome, hypandrium and paraproct structure. Comments on variation in fore wing venation, and new records for B. troglophilica are included. A revised generic diagnosis is also presented.
