In the last three decades some faunal surveys of Drosophilidae have been done in several environments Neotropical region, especially Brazil. But approximately 30 to 50% drosophilids Brazil not yet described, and degradation biomes causes a profound loss species diversity, as well information about present structureof their communities. This is situation with pampas biome, which covers southernmost Brazil, all Uruguay, central region eastern Argentina. For study, seasonal collections were...

Assemblages of drosophilids have been characterised in several environments the Brazilian territory, like Atlantic Rain Forest, urban areas, cerrados, Amazon and others. The present survey is first attempt to characterise fauna Drosophilidae mangrove forests, an environment typical tropical coasts worldwide. Twenty-eight samples were collected from three main forests Santa Catarina Island, southern Brazil, using banana-baited traps hung trees. Samples taken January (summer), April (autumn),...

Understanding patterns of ecological specialization, the processes underlying niche partitioning and how they translate into structure interaction networks is a persistent challenge in ecology. Advances on this regard are limited by prevalent focus single spatial scales, lack tests mechanisms scarce investigation some types interactions. Here we investigated between plants florivores (flower‐breeding drosophilids, FBD) at species‐ community‐level local regional tested relative importance...

Although studies on drosophilid (Diptera, Drosophilidae) assemblages have become relatively abundant in the past decades, many environments remain to be searched. The present study investigates composition, species abundances and richness of two localities municipality Cruz Alta, northwestern region state Rio Grande do Sul, a point contact between biomes Atlantic Forest Pampa: (i) an urban area (2007), constituted by domestic orchard with Citrus trees, (ii) forested area, Centro de Educação,...

The Brazilian Pampa (the southernmost end of the country) is currently a highly modified environment because increasing agricultural activities. In many places, only small parts grasslands remain inside an landscape. Drosophilidae (Diptera) have been widely used as potential bioindicators to monitor effects anthropogenic changes in natural environments. However, fauna Biome from and disturbed environments, still remains largely unknown. present study represents one first attempts fill this...

Brazilian fauna of drosophilids has been researched in various ecosystems, but those mangrove forests remain overlooked Brazil and elsewhere. The present study attempts to characterise the assemblages this environment, based on 28 collections taken three areas Santa Catarina Island, southern Brazil. mangroves surveyed were different their surroundings, which varied from highly urbanised conservation with natural vegetation. Overall, 69 species collected, no remarkable difference was detected...

The genus Rhinoleucophenga Hendel comprises 26 nominal species with New World distribution. In the present study, two new are described from samples in Pampa and Caatinga biomes Brazil, R. punctuloides sp. nov. trivisualis nov., respectively. is a sibling of punctulata Duda. Furthermore, females joaquina Schmitz, Gottschalk & Valente were found for first time description presented. A taxonomic dichotomous key pictures given recorded biomes. Neotropical open environments areas high...

Infections by the endosymbiotic bacterium Wolbachia developed a rapid global expansion within Old World Drosophila species, ultimately infecting also Neotropical species. In this sense, screenings are necessary to characterize new variants of or hosts, and in order map dynamics already known infections. paper, we performed double screening approach that combined Dot-blot PCR techniques reevaluate infection status species from willistoni subgroup Drosophila. Genomic DNA isofemale lines...

Diptera is a megadiverse order, reaching its peak of diversity in Neotropics, although our knowledge dipteran fauna from this region grossly lacking. This applies even to the most studied families, such as Drosophilidae. Despite prominence, aspects biology these insects are still poorly understood, especially those linked natural communities. Field studies on drosophilids highly biased towards fruit-breeding species. Flower-breeding drosophilids, however, worldwide distributed, tropical...

The present paper brings together survey data from nine collection sites in Santa Catarina state, southern Brazil. Samples were obtained during about four years forested, coastal and urban areas. Flies attracted by fermented banana baits captured traps. Among the species of genus Zygothrica Wiedemann 1830 collected, apopoeyi Burla 1956, Z. bilineata (Williston 1896), dispar (Wiedemann 1830), Z./ lanceolata nigropleura Grimaldi 1987, poeyi (Sturtevant 1921) recorded for first time state and,...

The genus Rhinoleucophenga Hendel comprises 18 nominal species and has a Neotropical Nearctic distribution.A new was found in collection Florianópolis, SC, Brazil, is described as joaquina sp.nov.The specimens were reared from fl owers of Dyckia encholirioides (Bromeliaceae), collected region restinga on the dunes.The use breeding site for never been reported before.

Abstract This list contains information on the Drosophilidae that occur in Brazilian state of Pará, Amazon biome, and an analysis current knowledge based museum material literature records. includes a detailed account deposited entomological collections Museu Paraense Emílio Goeldi de Zoologia da Universidade São Paulo, up to 2015. In total, 122 species were registered, including 27 new records for Pará 22 are Amazon; instance, genera Diathoneura Rhinoleucophenga, three Brazil, (Drosophila...

Abstract Cryptic species represent a substantial fraction of the diversity Drosophilidae, hampering studies on ecologies and their evolution. Anthophilous within Drosophila lutzii group encompass some most widely distributed Neotropical lineages. Nevertheless, ranges, ecologies, divergence times, phylogenetic relationships are largely unknown. In this study, we analyzed cryptic complex occurring in Southern Brazil shed light ecological evolutionary processes underlying current patterns...

The Pampas biome is a subtropical–temperate grassland region that presents striking climatic characteristics, such as temperatures below zero in the winters and up to 40°C summers. Hence, long sampling periods are necessary better understand structure of Drosophilidae assemblages through current conditions heterogeneous landscape Pampas. Samples drosophilids were taken natural urban areas during 12 periods. environmental influence on was temporally spatially analyzed nonmetric...

Abstract Despite the fact that Drosophilidae is a very diverse and well‐studied taxon, New World genus Rhinoleucophenga yet poorly understood even in regard to species distribution morphological variability pattern. In this sense, R. punctulata widely distributed Neotropical region. Specimens of were collected from different biomes Brazil: Pampa, Cerrado Caatinga sensu strictu , southern Amazonian savannah enclave area. Geographical variations external body morphology spermatheca noticed...

Abstract Diptera is a megadiverse order, reaching its peak of diversity in Neotropics, although our knowledge dipteran fauna this region grossly deficient. This applies even for the most studied families, as Drosophilidae. Despite position evidence, aspects biology these insects are still poorly understood, especially those linked to natural communities. Field studies on drosophilids highly biased fruit-breeders species. Flower-breeding drosophilids, however, worldwide distributed, tropical...

Rhinoleucophenga Hendel is an endemic genus of the New World with most species recorded in Brazil. obesa (Loew) seemed to be widespread species, being United States America, Mexico and In Neotropical region, identifications R. were commonly based on description non-type specimens determined by Costa Lima (1935) Malogolowkin (1946), although their identities doubtful. However, recent redescription from type-series Texas, USA, confirmed a long period misidentifications new cantareira Vilela...
