Podium angustifrons Kohl 1902 is a species of solitary wasp which nests in pre-existing cavities, with neotropical distribution in Argentina, Bolivia, Brazil, Colombia, Guyana and French Guyana. The aim of this study was to investigate the nesting biology of P. angustifrons, discussing aspects of their life history. To capture its nests, wooden trap-nests were installed in the Parque Municipal das Araucárias, Guarapuava (PR), Brazil, from January 2003 to April 2009. A total of 29 nests were collected, all during the warmer months. These showed no vestibular and intercalary cells, and their closures were made up of chewed plants and mud mixed with organic materials and resin-coated surfaces, sometimes showing a layer of lichens. The cells were provisioned with various wild species of cockroaches (Chorisoneura sp, Riata sp and Helgaia sp) in the nymph stage and/or adults. The sex ratio was 4.6 females per male, significantly higher that the expected 1:1. Most pre-pupae entered diapause in winter with development time ranging from 187 to 283 days for females and 180 to 283 days for males. Deaths occurred in 41.66% of cells provisioned, 33.33% were attributed to faulty development and 8.33% to Chrysididae.

We reported a new record of Teratohyla midas for Northeast Brazil and extending its distribution in 1,200km east from the nearest reported area. Additionally we constructed a distribution map based on literature records. Previously to this study, this species was known to occur in Ecuador, Peru, Colombia, Brazil (states of Amazonas and Rondônia), and an isolated population in French Guyana. Also, this record represents the first for Centrolenidae in transitional forests between Cerrado and Amazon biomes.

<p><strong>Abstract</strong></p> <p>The BepiColombo spacecraft was launched on 20 October 2018 from the European spaceport in French Guyana and is currently on its way to Mercury. On its way, the spacecraft will swing-by Mercury six times in its stacked configuration, before releasing the Mercury Magnetospheric Orbiter (MMO) and the Mercury Planetary Orbiter (MPO) in their corresponding orbits around the target planet.</p> <p><strong>Introduction</strong></p> <p>Mercury is in many ways a very different planet from what we were expecting. On 20 October 2018 the BepiColombo spacecraft [1] started its 7 year journey to the innermost terrestrial planet to investigate on the fundamental questions about its evolution, composition, interior, magnetosphere, and exosphere.</p> <p>BepiColombo is a joint project between the Euro- pean Space Agency (ESA) and the Japanese Aero- space Exploration Agency (JAXA). The Mission con- sists of two orbiters, the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (MMO). From their dedicated orbits the two space- craft will be studying the planet and its environment.</p> <p>The mission has been named in honor of Giuseppe (Bepi) Colombo (1920–1984), who was a brilliant Italian mathematician, who made many significant contributions to planetary research and celestial mechanics.</p> <p>During the cruise phase, the spacecraft flies in a stacked configuration: the MMO and MPO are mounted ontop of the Mercury Transfer Module (MTM). As a consequence, most remote sensing instruments onboard the MPO are mounted towards the MTM and have a fully obstructed field-of-view. The MMO instrumentation is shielded by a protection shield (MOSIF) and several instruments still await the deployment on measurement booms.</p> <p>Despite the reduced instrument availability, scientific and engineering operations will be scheduled during the cruise phase, especially during the swing-bys.</p> <p><strong>Mercury Swing-bys</strong></p> <p>Following the Earth and two Venus swing-bys, six Mercury swing-bys are foreseen from October 2021 until 9 January 2025. The poster will discuss the flyby geometries and potential operation opportunities, in comparison with the three MESSENGER Mercury swing-bys from 2008 and 2009 [2][3].</p> <p><strong>References: </strong>[1] Benkhoff, J., et al.

For slightly more than a century only the type specimen has been known for Pyrgometopa penicillata, a monotypic genus of Drosophilidae whose sole species has an ocellar triangle distended into a bizarre tubercle bearing a tuft of large, spine-like bristles in both sexes. Here we report additional specimens of both sexes of the species, recently rediscovered from Brazil, Peru and French Guyana, allowing us to state that Pyrgometopa is a junior synonym for Stegana, a large cosmopolitan genus. A detailed redescription of Stegana penicillata (Kertész) new combination is provided, including new morphological information, like the male and female terminalia, the egg and a short discussion is provided about its hallmark feature.

Two new species of Sistotremastrum collected in French West Indies and French Guyana are described and illustrated. Morphological studies and molecular sequence data from two ribosomal DNA regions (ITS and 28S rDNA) support the recognition of S. fibrillosum and S. aculeocrepitans, two species characterized by their hyphal cords and basidia with 4 sterigmata.
