Revisão dos Lekiini (Diptera, Tachinidae) neotropicais

The Leskiini (Diptera : Tachinidae, Tachininae) is a cosmopolitan tribe found in all geographic regions. It comprises 49 genera throughout the world, 18 of them occurring in the neotropics: Beskioleskia Townsend, Galapagosia Curran, Genea Rondani, Geneodes Townsend, leskia Robineau-Desvoidy, Metamyobia Townsend, Mintholeskia Townsend, Parthenoleskia Townsend, Proleskiomima Townsend, Spathipalpus Rondani, Stomatodexia Brauer & Bergenstamm, Tapajoleskia Townsend, Tipuloleskia Townsend, Trichopyrrhosia Townsend, Trochiloglossa Townsend, Trochiloleskia Townsend, Uruleskia Townsend and Urumyobia Townsend. National and foreign collections were studied and type-material of almost all genera were examined. This revision of the neotropical Leskiini the taxonomic changes proposed resulted in 1O valid genera to this region: Genea Rondani; Leskia Robineau-Desvoidy; Proleskiomima Townsend; Spathipalpus Rondani; Stomatoderia Brauer & Bergenstamm; Tipuloleskia Townsend; Uruleskia Townsend; Eumyobia Townsend and Sipholeskia Townsend, (both included in Leskia Robineau-Desvoidy synonymy had their status revalidated) and Murya gen.nov. . The other genera received the following treatment: Beskioleskia, Mintholeskia and Trichopyrrhosia were transferred to Dexiinae subfamily based on their characteristic hinged distiphallus, the second one (Mintholeskia) being a misindentification of Neosolieria Townsend. Trochiloleskia was included in the synonymy of Eumyobia and Trochiloglossa in the synonymy of Sipholeskia. Three monotypic genera: Parthenoleskia, Tapajoleskia and Urumyobia Townsend were synonymized with Leskia, while Galapagosia, Geneodes and Metamyobia were synonymized with Stomatodexia. Besides the taxonomic changes this paper revises Eumyobia; Sipholeskia and Uruleskia, with the redescription of their species, including the type-species; description of four new species of Uruleskia from the north of Brazil: U. alba spec. nov., U. extremipilosa spec. nov., U. infima spec. nov. and U. parcapilosa spec. nov. and describes Murya gen.nov. for one new species Murya bicolor spec. nov. One new combination Sipholeskia tropica (Townsend) comb. nov. is proposed. Illustrations of the morphological characterers especially the male terminalia, keys to genera and species are also presented.CAPESA tribo Leskiini (Diptera: Tachinidae, Tachininae) é cosmopolita e é encontrada em todas as regiões geográficas. Ela compreende 49 gêneros em todo o mundo, 18 deles ocorrendo na região neotropical: Beskioleskia Townsend, Galapagosia Curran, Genea Rondani, Geneodes Townsend, Leskia Robineau-Desvoidy, Metamyobia Townsend, Mintholeskia Townsend, Parthenoleskia Townsend, Proleskiomima Townsend, Spathipalpus Rondani, Stomatodexia Brauer & Bergenstamm, Tapajoleskia Townsend, Tipuloleskia Townsend, Trichopyrrhosia Townsend, Trochiloglossa Townsend, Trochiloleskia Townsend, Uruleskia Townsend e Urumyobia Townsend. Coleções nacionais e estrangeiras foram estudadas e material tipo de quase todos os gêneros foi examinado. Neste trabalho sobre os Leskiini neotropicais as mudanças taxonômicas propostas resultaram em 10 gêneros válidos para esta região: Genea Rondani; Leskia Robineau-Desvoidy; Proleskiomima Townsend; Spathipalpus Rondani; Stomatodexia Brauer & Bergenstamm; Tipuloleskia Townsend; Uruleskia Townsend; Eumyobia Townsend e Sipholeskia Townsend, (ambos incluídos em sinonímia com Leskia Robineau-Desvoidy tiveram seus status revalidados) e Murya gen. nov. Os outros gêneros receberam o seguinte tratamento: Beskioleskia, Mintholeskia and Trichopyrrhosia foram transferidos para a subfamília Dexiinae baseado em seu distifalo característico, o segundo (Mintholeskia), é uma identificação errônea de Neosolieria Townsend. Trochiloleskia foi sinonimizado com Eumyobia e Trochiloglossa foi sinonimizado com Sipholeskia. Três gêneros monotípicos : Parthenoleskia, Tapajoleskia e Urumyobia Townsend foram sinonimizados com Leskia, enquanto Galapagosia, Geneodes e Metamyobia foram sinonimizados com Stomatodexia. Além das mudanças taxonômicas este trabalho revisa os gêneros Eumyobia; Sipholeskia e Uruleskia, com a redescrição de suas espécies, inclusive a espécie tipo; descrição de quatro espécies novas de Uruleskia da região norte do Brasil: U. alba spec. nov., U. extremipilosa spec. nov., U. infima spec. nov. e U. parcapilosa spec. nov. e descreve Murya gen. nov. para uma espécie nova Murya bicolor spec. nov.

Revisão de Chrysotachina Brauer & Bergenstamm (Diptera, Tachinidae) da América do Sul

Revision of the Chrysotachina species with occurrence in South America. The species belonging to this genus are easily distinguished from most of the other tachinids by their metallic colour - green, blue or purple, although grey species are known. From the fifteen species cited in the literature for South America, twelve are redescribed: C. aldrichi Nunez et alli, in press; C. braueri Townsend, 1931; C. currani Nunez et alli, in press; C. equatorialis (Townsend, 1912); C. panamensis Curran, 1939; C. peruviana Townsend, 1919; C. purpurea Curran, 1939; C. tieta Nunez et alli, in press; C. townsendi Curran, 1939; C. tropicalis Nunez et alli, in press; C. viridis Nunez et alli, in press; C. willistoni Curran, 1939. The following three species - C. ornata (Townsend, 1927); C. ruficornis (Walker, 1852) and C. tatei Curran, 1939 - are not íncluded in this revision as none material of them was examined. C. ruficornis is cited in the catalogue of GUIMARÃES (1971) as ''unrecognized". The type material of C. peruviana and C. equatorialis was examined. Illustrations of the male terminalia and of two larvae are presented. An identification key for the species from South America is also presented.

Revision of neotropical genea rondani (Diptera, Tachinidae, Tachininae, Leskiini)

The Neotropical species of Genea Rondani, 1850 (Diptera, Tachinidae, Tachininae, Leskiini) are revised by the examination of type-material of almost all species and a large material deposited in many scientific collections. G. australis (Townsend), G. brasiliensis (Townsend), G. gracilis James, G. jaynesi (Aldrich), G. major (Townsend), G. pellucens (Curran), G. tenuirostris (James), G. trifaria (Wiedemann) were keyed and redescribed with the first descriptions of male terminalia. G. longipalpis (Wulp) was not included in this study as no material was examined and the available data are restricted to the original description. G. glossata (Townsend) is proposed as a junior synonym of G. trifaria. G. paulistana sp. nov. from São Paulo is proposed as a new species

Uruleskia Townsend (Diptera, Tachinidae): redescription of the type-species, description of new species and key to identification

The unique species of Uruleskia Townsend, 1934 (Diptera, Tachinidae) - U. aurescens Townsend, 1934 - is recorded only from Brazil. Its holotype and paratypes are herein redescribed with illustration of male terminalia. The examination of a material mainly from Instituto Nacional de Pesquisa da Amazônia (INPA, Manaus, Brazil) enabled the description of four new species - Uruleskia alba sp. nov., Uruleskia extremipilosa sp. nov., Uruleskia infima sp. nov. and Uruleskia parcapilosa sp. nov. A key to the identification of all five species is also presented

Efficiency of capture of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) with mosquito killer light traps

Tuta absoluta (Meyrick) is a cosmopolitan pest that affects leaves and fruits, causing damage to crops. Various control techniques are used to eliminate adults and larvae; however, none of themis completely effective. Thus, this study tested the use of a light trap with an ultraviolet lamp and an electrical device to control T. absoluta in a tomato greenhouse (‘Grazianni’) located in Paty do Alferes (Brazil) and recorded the best capture period. For this, three FIX model mosquito traps were placed inside the greenhouse (2.4 m high, 1.2 m apart) during one lunar cycle. The catch was evaluated in the following time periods: from 7:00 pm to 10:30 pm, from 10:30 pm to 02:00 am, and from 02:00 to 05:30 am. A total of 6,886 specimens were collected. The time interval from 7:00-10:30 pm resulted in the highest abundance captured (54.3%), similar to previous data on the flight period of T. absoluta. These results contribute to the Integrated Pest Management of the tomato crop, an alternative to the exclusive use of chemical control methods which fail to efficiently control the tomato moth

Belvosia sp. (Diptera: Tachinidae) Parasitizing Halysidota sp. (Lepidoptera: Arctiidae) caterpillars on Ficus benjamina (Moraceae) in Brazil

Ficus benjamina L. (Moraceae) is an exotic ornamental plant in Brazil. The aim of this study was to identify a defoliator and its parasitoid on F. benjamina plants in Viçosa, Minas Gerais, Brazil and to determine the number of pupae and the emergence of lepidopteran and a dipteran. Four Halysidota sp. (Lepidoptera: Arctiidae) groups, with 158, 144, 137 and 129 last-instar caterpillars aggregated on the trunks of 4 F. benjamina trees. These caterpillars were collected, held in plastic containers with ficus leaves until development and emergence were completed. Adults of 1 undescribed lepidopteran species (Halysidota) and 1 dipteran species [Belvosia (Tachinidae)] emerged from the Halysidota pupae. An average of 118 viable Halysidota pupae per group were formed, and an average of 62.5 Belvosia individuals emerged from these host pupae per Halysidota group. From a grand total of 472 Halysidota pupae only one adult emerged. Halysidota sp. damaged F. benjamina plants in Viçosa, Minas Gerais, Brazil, but this defoliator was parasitized by Bel- vosia sp. The findings reported here indicate that Belvosia sp. appears to have the potential to reduce populations of Halysidota sp. and possibly protect F. benjamina in ornamental plantings.Ficus benjamina L. (Moraceae) é uma espécie ornamental exótica cultivada no Brasil. O objetivo foi identificar um desfolhador e seu parasitoide em plantas de F. benjamina em Viçosa, Minas Gerais, Brasil e determinar o número de pupas e a taxa de emergência dos Lepidoptera e dos Diptera. Quatro grupos de Halysidota sp. (Lepidoptera: Arctiidae), com 158, 144, 137 e 129 lagartas de últimos estádios agregadas sobre os troncos de 4 árvores de F. benjamina foram coletados. Uma espécie não-descrita de Lepidoptera (Halysidota) e outra de Diptera [Belvosia (Tachinidae)] foram obtidas. Os números de pupas foram, em média, de 118 por grupo. A taxa de emergência do Diptera foi de 62,5 indivíduos por grupo de lagartas. Halysidota sp. danificou plantas de F. benjamina em Viçosa, Minas Gerais, Brasil, mas foi parasitada por Belvosia sp. Isso mostra a importância desse Tachinidae para reduzir populações deste desfolhador de F. benjamina, a qual é cultivada como ornamental
