ABSTRACT
Three new species of Stilobezzia Kieffer, 1911 are described and illustrated from the Brazilian Amazon, two in the nominotypical subgenus Stilobezzia: S. (Stilobezzia) brasiliensis n. sp. and S. (Stilobezzia) campinaranensis n. sp., and one in the subgenus Acanthohelea: S. (Acanthohelea) medialuna n. sp. We also redescribe and re-illustrate S. (Stilobezzia) maculata Lane based on the examination of type material and additional specimens. In addition, S. (Eukraiohelea) proxima Cazorla & Felippe-Bauer, S. (Eukraiohelea) quasielegantula Cazorla & Felippe-Bauer, S. (Stilobezzia) chaconi Macfie, S. (Stilobezzia) glauca Macfie, and S. (Stilobezzia) maculata are recorded for the first time from the state of Amazonas, northern Brazil. The number of Stilobezzia species in Brazilian Amazon increases from 11 to 19.

In the present study, three new species of Tanytarsus, collected in Brazilian Amazonia, are described and illustrated as adult males: T. pollicis sp. nov., T. marianae sp. nov. and T. rafaeli sp. nov. Tanytarsus pollicis is placed in kiche species group due to its bilobed superior volsella. Tanytarsus marianae and T. rafaeli are not placed in any known species group, and although these two new species share characters that suggest they may be closely related, we do not propose that they form a new species group for Tanytarsus without prior phylogenetic analysis.

Tanytarsus is a highly diverse genus of Chironomidae (Diptera), distributed worldwide. In the Neotropics, 84 species are known, but only five have been recorded from Central America to date. In the present article, two new species of the Tanytarsus ortoni species group are described and illustrated based on male specimens collected from Costa Rica, T. braini sp. nov. and T. costarica sp. nov.

We assessed the immature stages of Ceratopogonidae (Diptera) in artificial containers in an urban forest fragment in Manaus (Brazil), including their behavioral, biological and ecological information. In addition, we evaluated the effects of deforestation in an open and forested area on Ceratopogonidae communities. Immatures were sampled between August 2012 and July 2014 in artificial containers installed in both habitat types. We collected 685 immatures of seven morpho-species of Bezzia Kieffer, Culicoides Latreille, Dasyhelea Kieffer, Forcipomyia Meigen, and Palpomyia Meigen. In the open area, we recorded higher temperature and electrical conductivity values than in the forested area; however, these variables did not differ between seasons. Water volume was higher in open area and in rainy season, while pH was similar in both areas and seasons. Species richness was higher in forested area, but did not differ between seasons. We did not record differences in abundance between areas or seasons. Community composition differed between areas, but not between seasons. We provide the first records of Culicoides (Hoffmania) insignis Lutz and C. (Haematomyidium) quasiparaensis Clastrier in artificial containers from the state of Amazonas. Our results suggest that the preservation of forested areas in Amazonas is fundamental for the maintenance of the life cycle of some species of Ceratopogonidae.

A new species from Manaus, Amazonas, Brazil, Dasyhelea eloyi Díaz & Ronderos, is described, illustrated and photomicrograph as larva, pupa and male and female adults based on examination with binocular and scanning electron microscopes. This new species, a typical member of the Dasyhelea grisea species group, is compared with the most similar congeners D. necrophila Spinelli & Rodriguez and the Nearctic D. pseudoincinsurata Waugh & Wirth.

A catalog of type specimens of Heteroptera (Insecta: Hemiptera) deposited in the Instituto Nacional de Pesquisas da Amazônia (INPA), Manaus, Brazil, is presented and updated to May, 2012. A total of 37 holotypes and 61 lots of paratypes of 78 species are listed in their families: Miridae and Reduviidae (infraorder: Cimicomorpha); Mesoveliidae and Velfidae (Gerromorpha); Belostomatidae, Naucoridae, and Notonectidae (Nepomorpha); and Coreidae, Geocoridae [the older sense of "Lygaeidae"], and Pentatomidae (Pentatomomorpha). The taxa are presented alphabetically by infraorders, families, and genera, followed by epithet, bibliographic citation, type category, collection number, method of preservation, and present data on the labels. When necessary, we added localities data, and changes in taxonomic status of some species

A new species from the Neotropical Region, Stilobezzia (Stilobezzia) pseudopunctulata Cazorla & Ronderos, is described and illustrated based on male and female adults and pupal exuviae. Adults were collected in the Argentinian provinces of Chaco, Formosa, Corrientes and Buenos Aires, and in Santa Cruz, Bolivia. The pupa was collected from mats of floating aquatic macrophytes in a lagoon in Ilha da Marchantería, in the vicinities of Manaus, Brazil. This new species is compared with its similar congener Stilobezzia punctulata Lane, from which it can be mainly distinguished by the wing with only two dark spots, the parameres longer and hook-shaped, the pupal respiratory organ with 11-12 pores and the very short apicolateral processes of the anal segment.
Uma espécie nova da Região Neotropical, Stilobezzia (Stilobezzia) pseudopunctulata Cazorla & Ronderos, é descrita e ilustrada a partir de adultos macho e fêmea e exúvia pupal. Os adultos foram coletados nas províncias argentinas de Chaco, Formosa, Corrientes e Buenos Aires e em Santa Cruz, Bolívia. A pupa foi coletada em tapetes de macrófitas aquáticas flutuantes em um lago na Ilha de Marchantaria, nas proximidades de Manaus, Brasil. Esta espécie nova é comparada com a sua congênere semelhante Stilobezzia punctulata Lane, a partir da qual pode ser distinguida principalmente pela asa com apenas duas manchas escuras, parâmeros mais longos e em forma de gancho, órgão respiratório da pupa com 11-12 poros e processo apicolateral do segmento anal muito curto.
ABSTRACT
The previously unknown pupa and adult male of Neobezzia fittkaui Wirth & Ratanaworabhan (Diptera, Ceratopogonidae). The pupa of Neobezzia fittkaui Wirth & Ratanaworabhan, 1972, collected from a mat of floating fern (Salvinia auriculata Aubl., Salviniaceae) in Ilha da Marchantaria near Manaus, Brazil and the reared adult male are described, photographed and illustrated for the first time. This is the first detailed pupal description for the genus Neobezzia Wirth & Ratanaworabhan.

ABSTRACT
Adults of Tabanidae may become serious pests wherever they occur due to their attack to humans and others animals. Tabanids were captured near ground, water surface and at 25 m high on primary forests and forest gaps of anthropogenic origin, to understand their abundance, seasonality, diversity and similarity on such environments. Collections were carried out in the Base II of the War Instruction Center in the Jungle (CIGS) located at 54 km from Manaus municipality, Amazonas state. Two Malaise flight interception traps and four attraction traps (two suspended at 25 m high and two above the water surface of igarapé) were installed in forest gap and primary forest, areas for 10 consecutive days, during 15 months. A total of 2,643 specimens of 66 species were captured. Diachlorini (35 species /11 genera) was the most abundant tribe, followed by Tabanini (19 species /three genera), Chrysopsini (seven species /one genus) and Scionini (five species /two genera). Seventeen species were captured only in the primary forest, 11 in the anthropic clearing, and 38 species were common to both environments. The most abundant species were Phorcotabanus cinereus (Wiedemann), Tabanus occidentalis L, Chrysops laetus Fabricius and Tabanus angustifrons Macquart. The greatest richness was found in drier months (September/October) in both areas. Theforest gap showed higher abundance of specimens (1,827) than the primary forest (816). Traps suspended above the water surface were the most efficient (1,723 specimens) probably due to the dispersion of horseflies over small streams.
