Abstract
Three yeast isolates were obtained from soil and rotting wood samples collected in an Amazonian rainforest biome in Brazil. Comparison of the intergenic spacer 5.8S region and the D1/D2 domains of the large subunit rRNA gene showed that the isolates represent a novel species of the genus Saccharomycopsis. A tree inferred from the D1/D2 sequences placed the novel species near a subclade containing Saccharomycopsis lassenensis, Saccharomycopsis fermentans, Saccharomycopsis javanensis, Saccharomycopsis babjevae, Saccharomycopsis schoenii and Saccharomycopsis oosterbeekiorum, but with low bootstrap support. In terms of sequence divergence, the novel species had the highest identity in the D1/D2 domains with Saccharomycopsis capsularis, from which it differed by 36 substitutions. In contrast, a phylogenomic analysis based on 1061 single-copy orthologs for a smaller set of Saccharomycopsis species whose whole genome sequences are available indicated that the novel species represented by strain UFMG-CM-Y6991 is phylogenetically closer to Saccharomycopsis fodiens and Saccharomycopsis sp. TF2021a (=Saccharomycopsis phalluae). The novel yeast is homothallic and produces asci with one spheroidal ascospore with an equatorial or subequatorial ledge. The name Saccharomycopsis praedatoria sp. nov. is proposed to accommodate the novel species. The holotype of Saccharomycopsis praedatoria is CBS 16589T. The MycoBank number is MB849369. S. praedatoria was able to kill cells of Saccharomyces cerevisiae by means of penetration with infection pegs, a trait common to most species of Saccharomycopsis.

Abstract
Ten yeast isolates representing four candidate novel species of the genus Teunomyces were obtained from different species of mushrooms and drosophilids collected in an Amazonian Forest biome in Brazil. Sequence analyses of the ITS 5.8S region and the D1/D2 domains of the large subunit rRNA gene showed that four isolates were phylogenetically related to Teunomyces stri, two isolates related to Teunomyces atbi, two isolates related to Teunomyces aglyptinius, and another two isolates related to Teunomyces aglyptinius, Teunomyces barrocoloradensis, Teunomyces gatunensis and Teunomyces stri. The four novel species differ by 3 % or more of sequence divergence in D1/D2 domains from their closest relatives. These species were isolated from basidiocarps of the mushrooms Marasmiellus volvatus, Tricholomopsis aurea, Hydropus sp. and Favolus tenuiculus, or drosophilids feeding on these substrates. The names Teunomyces gombertii f.a., sp. nov. (holotype CBS 16168T; Mycobank MB849065), Teunomyces landelliae f.a., sp. nov. (holotype =CBS 16169T; Mycobank MB 849066), Teunomyces ledahaglerae f.a., sp. nov. (holotype CBS 16170T; Mycobank MB 849067) and Teunomyces paulamoraisiae f.a., sp. nov. (holotype CBS 16120T; Mycobank MB 849068) are proposed for these species.

Abstract
INTRODUCTION French Guiana is a French territory bordering Brazil and Suriname where the COVID-19 pandemic has severely strained the French Guianese health system. The people working on illegal gold mining sites in French Guiana, also known as garimpeiros, are mainly of Brazilian origin. Their health conditions are precarious, they live under the radar of the surveillance system and therefore, assessment of their health is quite challenging.. The objective of this study was to describe their knowledge, attitudes and practices regarding COVID-19 and vaccination against this infection. METHODS We conducted an international multicenter cross-sectional survey between 1 March 2022 and 30 April 2022 in French Guiana and Suriname, using a structured questionnaire. RESULTS Eighty persons were included, 95.0% of whom were Brazilian. Most had good general knowledge of COVID-19. Antibiotic prophylaxis had been practiced by 10.0% of participants. Forty-three people thought they had been infected with COVID-19 (53.8%). Self-medication was frequent, often with antibiotics (32.6%, mostlychloroquine, ivermectin or azithromycin) and most had not consulted a physician for symptoms of COVID-19. A majority (62.5%) had received at least one dose of vaccine. Those who were ever tested for COVID-19 were the most likely to be vaccinated (PR = 1.98, p = 0.009). CONCLUSIONS Garimpeiros have a good level of knowledge about COVID-19 but the high consumption of antibiotics raises concerns about the selection of resistant bacteria. The vaccination rate was higher than that of the Guianese population. The most vaccinated individuals were those who had already taken a COVID test suggesting that these individuals had more exposure to the disease, were more health conscious, or had easier access to health centers.

Abstract
Sixteen yeast isolates representing two novel species of the genus Sugiyamaella were obtained from passalid beetles, their galleries and rotting wood collected in three sites of Amazonian Forest in Brazil. Sequence analyses of the ITS-5.8S region and the D1/D2 domains of the large subunit rRNA gene showed that the first species, described here as Sugiyamaella amazoniana f. a., sp. nov. (holotype CBS 18112, MycoBank 847461) is phylogenetically related to S. bonitensis with these species differing by 37 nucleotide substitutions and six gaps in D1/D2 sequences. S. amazoniana is represented by nine isolates obtained from the guts of the passalid beetles Popilius marginatus, Veturius magdalenae, Veturius sinuosus and Spasalus aquinoi, a beetle gallery and rotting wood. The second species, Sugiyamaella bielyi f. a., sp. nov. (holotype CBS 18148, MycoBank 847463), is most phylogenetically related to several undescribed Sugiyamaella species. S. bielyi is described based on seven isolates obtained from the guts of V. magdalenae and V. sinuosus, a beetle gallery and rotting wood. Both species appear to be associated with passalid beetles and their ecological niches in Amazonian biome.

Abstract
This paper provides an overview of the taxonomy of New World primates from proposals of the 1980's based on morphology to the great number of studies based on molecular data aiming for the elucidation of the phylogeny of New World monkeys. The innovations of the first molecular phylogeny presented by Schneider et al. (1993) positioned Callimico as a sister group of Callithrix and Cebuella; Callicebus as a member of the pitheciids; Brachyteles as sister to Lagothrix; and the night monkeys (Aotus), capuchins (Cebus) and squirrel monkeys (Saimiri) in the same clade with the small callitrichines. These results were subsequently confirmed by dozens of subsequent studies using data from DNA sequences. Some issues difficult to resolve with the phylogenetic analyses of DNA sequences, such as the diversification of the oldest lineages (pitheciids, atelids and cebids), and the confirmation of Aotus as a member of the Cebinae clade (together with Cebus/Saimiri), were clarified with new molecular approaches based on the presence or absence of Alu insertions as well as through the use of phylogenomics. At this time, all relationships at the intergeneric level had been deciphered, with the exception of the definition of the sister group of callitrichines (whether Aotus or Cebus/Saimiri are sister to callitrichines, or if Aotus, Saimiri and Cebus form a clade together). Future studies should prioritize the alpha taxonomy of most Neotropical primate groups, and the use of phylogenetic and geographic data, combined with reliable estimates of divergence times, to clarify the taxonomic status at species and genus level, as well as to help understand the evolutionary history of this remarkable and highly diversified group.
