Abstract Leurus Townes, 1946 is a small genus of Metopiinae (Hymenoptera: Ichneumonidae), consisting of 13 described species distributed in the Neotropics and the Nearctic region. The present work aims to contribute to the taxonomic knowledge of Leurus in Brazil. A total of 109 specimens were identified and 15 literature records were analyzed. The genus geographical occurrence was evaluated according to data obtained from the literature and labels of analyzed specimens. Five species of Leurus were identified for the Brazilian fauna: L. angustignathus, L. caeruliventris, L. discus, L. gracius and L. nostrus. New municipality records of occurrence were made for L. angustignathus in the state of São Paulo, L. caeruliventris in the states of Bahia, Distrito Federal, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná, Piauí and Rondônia; for, L. discus in the state of Alagoas and São Paulo, and L. gracius in the state of Minas Gerais, Rio de Janeiro, and São Paulo. Females of L. angustignathus and L. gracius were described for the first time in the present study. The genitalia of males of L. caeruliventris, L. discus and L. gracius were described and illustrated for the first time.

ABSTRACT Although the species richness of Stratiomyidae (Diptera) in Brazil (~340 species) is one of the highest for the family worldwide, we still do not know the actual number of species, the extent of their distribution, or the species seasonal dynamics for a single area in the Neotropics. The soldier fly fauna in the semideciduous seasonal forests, which cover a major area of the countryside of the state of São Paulo, is poorly known compared to the best-known areas in the Atlantic Forest for stratiomyids, such as the ombrophilous forests on the southeast coast. With the constant habitat fragmentation of the remnants of the semideciduous forests in the state for crops and pastures for cattle, we are losing valuable data about biodiversity. This study details the stratiomyids for a single area in the Neotropical Region, using a standardized collecting methodology with Malaise traps, from May 2010 to December 2011. Here, we provide a list of 41 stratiomyid species and 25 genera in eight subfamilies from a total of 1,533 specimens collected in the Reserva Biológica e Ecológica Augusto Ruschi, Sertãozinho, Brazil. The current number of species/morphospecies reported for the state of São Paulo is raised to 113, with Merosargus golbachi James, 1971 in James and McFadden, 1971 and M. tripartitus James, 1971 in James and McFadden, 1971 reported for the first time to Brazil. Our analyses estimate even higher richness in the studied area, probably between 48 to 114 species, indicating that further collection efforts are needed.

Abstract This study aimed to assess the diversity, abundance and seasonal dynamics of Ophioniformes wasps collected throughout a year, as recorded in Malaise traps set at the Reserva Ecológica da Universidade Estadual do Mato Grosso do Sul, a Brazilian Savanna area in Aquidauana city, MS. A total of 621 specimens of Ophioniformes belonging to 11 subfamilies, 30 genera and 106 species were sampled. Despite the impressive number of species found, in a pattern of a few relatively abundant species and many rare ones, our data estimate even higher richness, probably between 125 to 165 species in the studied area. The genera Diadegma, Nonnus, Diradops, Meniscomorpha, Syzeuctus, Ophiopterus and Thyreodon are recorded for the first time in Mato Grosso do Sul State. Among the climatic variables evaluated, mean temperature and relative humidity were positively and significantly correlated with richness and abundance. Our data highlights the huge unknown species richness of these parasitoids in Brazil and the need of taxonomic studies efforts in the future.

As principais lacunas do conhecimento para estes organismos no estado e as perspectivas para estudos futuros são discutidas.

ABSTRACT A checklist composed of 105 species of parasitic Hymenoptera, which includes the non-aculeate Apocrita, recorded in the state of Mato Grosso do Sul (MS), Brazil, is presented. A new list, containing 153 genera obtained in recent surveys is also presented; out of these 131 are new records. The major knowledge gaps for these organisms in the State and the prospects for future studies for these organisms are discussed.

ABSTRACT Cryptophion Viereck, 1913 is a small Neotropical genus of Campopleginae, with seven described species, two recorded from Brazil. In this paper, a new species from the Atlantic Forest of southeastern Brazil is described and illustrated. In addition, a key to the Brazilian species is provided. Cryptophion atlanticus sp. nov. (holotype female deposited in DCBU: Brazil, São Paulo, São Luiz do Paraitinga, Parque Estadual da Serra do Mar) is diagnosed by mesoscutum more or less uniformly punctate, except the notaular region with coarser and irregular rugae, scutellum bearing irregular lateral longitudinal rugae; forewing with areolet not distinctly petiolate above and hind tarsal claw pectinate, but with a large space in the middle, and distinctly longer than the arolium.

The aim of this study was to characterize the Eiphosoma Cresson, 1865 (Hymenoptera, Ichneumonidae, Cremastinae) fauna in areas of organic crops production, in relation to abundance, richness and diversity of species. Fourteen Eiphosoma species were identified, two new records to Brazil and three are new species identified. The system with median intensity management showed the highest values of abundance, richness and diversity in relation with higher and lower intensity of management. The climate variables showed less influence on the Eiphosoma fauna than the characteristics (composition and management) of the systems.

O objetivo deste trabalho foi caracterizar a fauna de Eiphosoma Cresson, 1865 (Hymenoptera, Ichneumonidae, Cremastinae) em áreas de agricultura orgânica, em relação à abundância, riqueza e diversidade de espécies. Foram identificadas quatorze espécies de Eiphosoma, das quais duas são novos registros para o Brasil e três são novas espécies. A horta com intensidade mediana de manejo e diversidade vegetal apresentou os maiores valores de abundância, riqueza e diversidade em relação às hortas com maior e menor intensidade de manejo. As variáveis climáticas demonstraram exercer menor influência na fauna de Eiphosoma do que as características (composição e manejo) das hortas.

Fauna de Campopleginae (Hymenoptera, Ichneumonidae) em hortas orgânicas em Araraquara e São Carlos, SP, Brasil. De março de 2006 a fevereiro 2007 foram realizadas doze amostragens utilizando armadilhas Malaise em cada uma das três áreas de cultivos orgânicos estudadas. Um total de 1773 espécimes foram identificados em dez gêneros de Campopleginae: Campoctonus Viereck, 1912, Campoletis Föster, 1869, Casinaria Holmgren, 1859, Charops Holmgren, 1859, Cryptophion Viereck, 1913, Diadegma Föster, 1869, Dusona Cameron, 1900, Hyposoter Förster, 1869, Microcharops Roman, 1910 e Venturia Schrottky, 1902. A riqueza e diversidade de gêneros foram semelhantes nos locais amostrados. Verificou-se baixa uniformidade, sendo Campoletis, Venturia e Casinaria os gêneros mais comuns e abundantes.

Campopleginae (Hymenoptera, Ichneumonidae) fauna in organic crops in Araraquara and São Carlos, São Paulo State, Brazil. From March 2006 to February 2007 twelve samples were performed using Malaise traps in each of the three studied organic crop areas. A total of 1773 specimens were identified in ten Campopleginae genera: Campoctonus Viereck, 1912, Campoletis Föster, 1869, Casinaria Holmgren, 1859, Charops Holmgren, 1859, Cryptophion Viereck, 1913, Diadegma Föster, 1869, Dusona Cameron, 1900, Hyposoter Förster, 1869, Microcharops Roman, 1910 e Venturia Schrottky, 1902. The richness and diversity of genera indices found were very similar. A low evenness was observed with Campoletis, Venturia and Casinaria being the most common and abundant genera.
