First Records of the Invading Species Drosophila Nasuta (Diptera: Drosophilidae) in the Amazon.

Invading species pose a growing threat to biodiversity, ecosystemic systems, regional economies, and public health. In recent decades, South America has received five exotic drosophilids species, some of which have invaded natural ecosystems and caused harm to agriculture. The most recent case is the Asian fly Drosophila nasuta Lamb. In the present study, we record D. nasuta in the Amazon, which is the largest and most biodiverse tropical rainforest in the world. Sampling of drosophilids was carried out between 2012 and 2017 in the Brazilian state of Pará. Drosophila nasuta was first detected on 1st July 2017, with 145 individuals of this species sampled among the 11,496 drosophilids caught. Although at low abundance, D. nasuta was recorded in forest fragments, anthropized fields, and urban environment. The records of the species occurred in the six municipalities of the state of Pará investigated at locations separated by approximately 700 km. In less than 10 years, D. nasuta has occupied approximately 2.5 million km2 in South America. The present findings assist in understanding the susceptibility of tropical forests to biological invasions.

The Program for Biodiversity Research in Brazil: The role of regional networks for biodiversity knowledge, dissemination, and conservation.

The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Revision of the Neotropical genus Domodon Reemer (Diptera: Syrphidae), with description of three new species.

The Syrphidae genus Domodon Reemer, 2013 so far included two species, D. zodiacus Reemer, 2013 and D. peperpotensis Reemer, 2014, both recorded only from Suriname. Additional specimens belonging to this genus have been collected in many other localities in South and Central America. In this paper, the genus is revised and three new species are described: D. caxiuana sp. nov. (northern South America), D. inaculeatus sp. nov. (northern South America), and D. sensibilis sp. nov. (Costa Rica). The distribution of D. peperpotensis is extended to include French Guiana. Photographs of the type material of the new species and illustrations of male genitalia of all species are provided, as well as a key to species.

New earthworm species of Righiodrilus (Clitellata, Glossoscolecidae) from eastern Amazonia.

Three new species of the glossoscolecid earthworm genus Righiodrilus are described from material collected in northern Pará and Maranhão States, Brazil. Rhigiodrilus gurupi n. sp. is characterized by four pairs of post-testicular spermathecae in xiv-xvii. Rhigiodrilus viseuensis n. sp. is distinguished by tubercula pubertatis in xix-xxiii and clitellum in xvi-xxiii. Rhigiodrilus moju n. sp. is the only species in the genus that lacks tubercula pubertatis. We provide an updated key and a distribution map for all species of Righiodrilus.

Drosophilidae (Insecta, Diptera) in the state of Pará (Brazil) / Drosophilidae (Insecta, Diptera) no estado do Pará (Brasil)

Abstract This list contains information on the Drosophilidae that occur in the Brazilian state of Pará, Amazon biome, and an analysis of the current knowledge of Drosophilidae based on museum material and literature records. This list includes a detailed account of the material deposited in the entomological collections of the Museu Paraense Emílio Goeldi and Museu de Zoologia da Universidade de São Paulo, up to 2015. In total, 122 species of Drosophilidae were registered, including 27 new records for the state of Pará and 22 are new records for the Amazon; for instance, the genera Diathoneura and Rhinoleucophenga, and three new records for Brazil, (Drosophila fasciola, Diathoneura flavolineata and Drosophila neochracea). The state of Pará is the third state in Brazil in terms of numbers of species of Drosophilidae, with 17% locally native species. Despite the high species richness, there is still a lot to be known about the states's Drosophilidae fauna. This study highlights the importance of scientific collections, particularly as an aid to study regional biodiversity.

Resumo As informações reunidas nesta lista referem-se à ocorrência de Drosophilidae no estado do Pará, bioma Amazônia com uma análise do estado de conhecimento do grupo. Este documento contém uma revisão detalhada do material depositado na Coleção Entomológica do Museu Paraense Emílio Goeldi e Museu de Zoologia da Universidade de São Paulo até 2015, bem como a análise de toda a literatura relevante. Um total de 122 espécies de Drosophilidae foi registrado, com 27 novos registros para o estado do Pará e 22 são novas ocorrências para a Amazônia. Entre estes o primeiro registro para os gêneros Diathoneura e Rhinoleucophenga, além de três registros novos para o Brasil (Drosophila fasciola, Diathoneura flavolineata e Drosophila neochracea). O estado do Pará é o terceiro maior estado brasileiro em termos de número de espécies registradas, com 17% das espécies com ocorrência exclusiva no Estado. Ainda assim há grandes lacunas para o conhecimento da fauna dos Drosophilidae do estado. Este estudo destaca a importância das coleções científicas, acima de tudo, como um elemento crucial para compreensão da biodiversidade regional.
