The SISBIOTA-Diptera Brazilian Network: A long-term survey of Diptera from unexplored Brazilian Western Arc of Amazon, Cerrado, and Pantanal

ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.

Intraspecific wing venation and phallosome taxonomy updates in species of Loneura Navs (Psocodea, Ptiloneuridae), with one new species from cave and key to Loneura species from Brazil.

cavernicola sp. nov. is here described and illustrated, based on male and female specimens collected in caves located in an ecotone region between the Brazilian Savannah (Cerrado biome) and the Atlantic Forest, in Minas Gerais state, southeastern Brazil. Illustrations are provided of 19 types of variation in the fore and hindwings veins of males and females. Illustrations are presented of the holotype of L. maracaensis Garca Aldrete, along with illustrations of 18 types of variation in the fore and hindwing veins of males and females. Additionally, a new methodology applied in some specimens of L. maracaensis to process the genital pieces allowed us to know the arrangement and delimitations of each of the sclerites and their possible position during copulation. We therefore propose a phallosome taxonomic update. In these everted male genitalia, the spermatic sac and attached glands were identified for the first time. An identification key is presented to the Brazilian species of Loneura, based on males.

Insect (Hexapoda) diversity in the Oceanic Archipelago of Fernando de Noronha, Brazil: Seasonality and Populational Density of Tabanidae (Diptera) / Diversidade de insetos (Hexapoda) no Arquipélago Oceânico de Fernando de Noronha, Brasil: Sazonalidade e Densidade Populacional de Tabanidae (Diptera)

Abstract: The seasonal population density is informed for two epidemiologically important species of bloodsucking Tabanidae, Tabanus occidentalis Linnaeus and T. pungens Wiedemann, recorded at the Fernando de Noronha archipelago that was never connected to the continent. The two species are widespread in the Neotropical Region, have not been recorded from any other oceanic island, and have most likely been introduced accidentally in the archipelago. Tabanus occidentalis dominated the samples, encompassing 99.6% of the specimens collected in the two local seasons, rainy and dry. Tabanus pungens was rarer, encompassing 0.4% of the specimens collected mainly in the dry season. The tabanids of Fernando de Noronha are able to transmit blood pathogens, bringing risks to the health of the livestock. They also pester the tourists, which brings losses to the local tourist industry. Larvae of both species were already collected in the water lettuce Pistia stratiotes Linnaeus and it is highly recommend that this introduced aquatic plant be removed from the ponds of Fernando de Noronha to control tabanid populations.

Resumo: A densidade populacional e a sazonalidade é informada para duas espécies epidemiologicamente importantes de Tabanidae, Tabanus occidentalis Linnaeus e T. pungens Wiedemann, registradas no arquipélago de Fernando de Noronha, o qual nunca foi conectado ao continente. As duas espécies estão amplamente distribuídas na Região Neotropical, não foram registradas em nenhuma outra ilha oceânica e provavelmente foram introduzidas acidentalmente no arquipélago. Tabanus occidentalis dominou as amostras, englobando 99,6% dos exemplares coletados nas duas estações locais, chuvosa e seca. Tabanus pungens foi mais rara, abrangendo 0,4% dos espécimes coletados principalmente na estação seca. Os tabanídeos de Fernando de Noronha são capazes de transmitir patógenos do sangue, trazendo riscos à saúde do gado. Eles também incomodam os turistas, o que traz prejuízos para a indústria turística local. Larvas de ambas as espécies já foram coletadas na alface d'água Pistia stratiotes Linnaeus e é altamente recomendável que esta planta aquática, introduzida no arquipélago, seja removida das lagoas de Fernando de Noronha para o controle de populações de tabanídeos.

Insect (Hexapoda) diversity in the oceanic archipelago of Fernando de Noronha, Brazil: updated taxonomic checklist and new records

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.
