ABSTRACT
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.

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.

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.

Planicapritermes Emerson, 1949 é um gênero de cupins da América do Sul com duas espécies nominais: Planicapritermes planiceps (Emerson, 1925) e Planicapritermes longilabrum Constantino, 1998. Os soldados deste gênero são caracterizados por ter mandíbulas fortemente assimétricas. Planicapritermes planiceps foi descrita com base em soldados e operários, e P. longilabrum somente em soldados. Aqui nós descrevemos e ilustramos os operários de P. longilabrum com base em espécimes coletados em Rondônia, Brasil. Também comparamos operários e soldados de P. planiceps e P. longilabrum, e descrevemos o ninho de P. planiceps.(AU)

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.
ABSTRACT
In this contribution, Colacus rubrofemoratus Sobral, Morais, Grossi new species (Coleoptera: Scarabaeidae: Dynastinae: Agaocephalini) is described and illustrated based on male specimens found in a transitional area of Caatinga, Atlantic Forest, and Cerrado in Brazil. In addition, the female of Colacus morio Ohaus, 1910 is redescribed, a distribution map for the genus is provided, and a new key to the species of Colacus is presented.

Two new species of Aegopsis Burmeister, 1847 (Coleoptera: Scarabaeidae: Dynastinae: Agaocephalini), Aegopsis diceratops Sobral Grossi new species and Aegopsis vazdemelloi Sobral Grossi new species, are described and illustrated based on specimens collected in Cerrado habitat in the Brazilian states of Minas Gerais and Mato Grosso. The new species are similar to A. bolboceridus (Thomson, 1860). A redescription of A. bolboceridus is provided along with remarks comparing characters among these three species. A distribution map and a male and female key to the species in the genus are provided.

The neotropical termite genus Neocapritermes Holmgren (1912) was revised by Krishna & Araujo (1968), who recognized 14 valid species. Two additional species were described by Constantino (1991), and another one by Bandeira & Cancello (1992). However, the imago of most species of Neocapritermes remain unknown. In this paper we describe for the first time the imago of Neocapritermes utiariti based on specimens from the State of Rondônia, Brazil. The examined material will be deposited in the Invertebrate Collection of the Instituto Nacional de Pesquisas da Amazônia, in Manaus, Amazonas, Brazil (INPA). Comparisons with other imagoes of Neocapritermes were made based on descriptions and figures from Krishna & Araújo (1968). The measurements were taken with an ocular micrometer following Roonwal's (1970) system of morphometric characters.

PURPOSE: Design a compact, ergonomic, and safe endoscope positioner dedicated to the sino-nasal tract, and the anterior and middle-stage skull base. METHODS: A motion and force analysis of the surgeon's movement was performed on cadaver heads to gather objective data for specification purposes. An experimental comparative study was then performed with three different kinematics, again on cadaver heads, in order to define the best architecture satisfying the motion and force requirements. RESULTS: We quantified the maximal forces applied on the endoscope when traversing the sino-nasal tract in order to evaluate the forces that the robot should be able to overcome. We also quantified the minimal forces that should not be exceeded in order to avoid damaging vital structures. We showed that the entrance point of the endoscope into the nostril could not be considered, as in laparoscopic surgery, as a fixed point but rather as a fixed region whose location and dimensions depend on the targeted sinus. CONCLUSION: From the safety and ergonomic points of view, the best solution would be a co-manipulated standard 6-degree of freedom robot to which is attached a gimbal-like passive remote manipulator holding the endoscope.
