Bethylidae are cosmopolitan wasps, with about 100 valid genera and about 2,400 valid species around the world, with 39 genera recorded from the Afrotropical region. This study aimed to determine the genera of Bethylidae occurring in Madagascar. The specimens were collected in Madagascar with several traps. A total of 18,915 specimens were obtained and 27 genera recognized. Nine of them are already recorded from Madagascar: Epyris, Glenosema, Goniozus Laelius, Pilomesitius Pristocera, Rhabdepyris, Sclerodermus, Sulcomesitius, and 18 genera are recorded for the first time: Alloplastanoxus, Apenesia, Bethylus, Cephalonomia, Diepyris, Dissomphalus, Formosiepyris, Heterocoelia, Holepyris, Kathepyris, Odontepyris, Parascleroderma, Plastanoxus, Prorops, Prosapenesia, Pseudisobrachium, Trachepyris and Tuberepyris. The only genus not founded was Messoria.

-The generic richness and abundance of Bethylidae collected in four different hillside areas of Atlantic rain forest from Espírito Santo, Brazil were studied. The sites are Santa Maria de Jetibá (SMJ), Domingos Martins (DM), Pancas (P) and Atílio Vivacqua (AV). A total of 2,840 specimens of 12 genera were collected. Lepidosternopsis Ogloblin and Bakeriella Kieffer are fi rst recorded from the State. Richness of taxa was calculated using fi rst-order Jackknife richness with EstimateS program. Genera accumulation curves were ran to evaluate the samples. Abundance data were adjusted to the geometric distribution. Parameter k was used to compare areas. The generic profi le was not equal for the sites we studied. The areas were considered disturbed. SMJ and DM presented genera richness bigger than in P and AV. The differences in the sites refl ect the different preservation of each environment. Pseudisobrachium Kieffer and Dissomphalus Ashmead are most dominant genera in SMJ, DM and P, and Anisepyris Kieffer in AV. This study emphasizes the fact of Dissomphalus as the most abundant genus in rain forests. The generic profi le found in AV is similar to that of some areas of Brazilian savannah.KEY WORDS: Alpha diversity, fi rst-order Jackknife, Neotropical region, new record, parasitoid wasp RESUMO -Estudou-se a riqueza e abundância de gêneros de Bethylidae coletados em quatro áreas de mata de encosta da Mata Atlântica do Espírito Santo, com estados de preservação diferentes: Santa Maria de Jetibá (SMJ), Domingos Martins (DM), Pancas (P) e Atílio Vivácqua (AV). Foram coletados 2.840 espécimes alocados em 12 gêneros, sendo Lepidosternopsis Ogloblin e Bakeriella Kieffer citados pela primeira vez para esse estado. A riqueza dos táxons foi obtida através do procedimento Jackknife com auxílio do programa EstimateS. Curvas de acumulação de gêneros foram construídas para avaliar o esforço amostral. Os dados se ajustaram à distribuição geométrica e calculou-se o parâmetro k para comparar as localidades. O perfi l genérico não foi equivalente em todas as localidades, e todas foram consideradas perturbadas. SMJ e DM apresentaram riqueza de gêneros maior em comparação com P e AV. As diferenças relatadas neste estudo para as áreas amostradas refl etem o grau diferente de preservação das matas. Pseudisobrachium Kieffer e Dissomphalus Ashmead foram os gêneros mais abundantes em SMJ, DM e P e Anisepyris Kieffer em AV. Este estudo reforça o fato de Dissomphalus ser mais abundante em fl orestas tropicais úmidas e que o perfi l genérico encontrado em AV assemelhase a dados publicados para o cerrado. PALAVRAS-CHAVE: Diversidade alfa, Jackknife de primeira ordem, Região Neotropical, citação nova, vespa parasitóide Bethylidae são vespas ectófagas quando adultas e ectoparasitóides idiobiontes primárias quando imaturas. Seus hospedeiros são larvas de Lepidoptera e Coleoptera que vivem em situações crípticas, tais como solo, serrapilheira, madeira e sementes (Evans 1964). Corpo achatado, cabeça prognata, fêmures anteriores largos e au...

The Thai Dissomphalus classification is reviewed, and 29 species are recognized. Previously described species, D. browni Terayama, D. chiangmaiensis Terayama, and D. thaianus Terayama had their known distribution and taxonomic variations broadened. Dissomphalus wusheanus Terayama is newly recorded from Thailand. Twenty-four new species,

Three new species of the Afrotropical Tuberepyris are described and illustrated, T. nihilus Azevedo et Mugrabi, sp. nov. (Madagascar), T. codex Azevedo et Mugrabi, sp. nov. (South Africa), and T. hamus Azevedo et Mugrabi, sp. nov. (Central African Republic). The male of Tuberepyris is described for the first time. T. basibrevis Lanes et Azevedo from Tanzania is evaluated and the genus is redefined. A key to species of Tuberepyris is provided.

Here we describe the flat wasp genus Makeraia gen. nov., and its three species M. migueli sp. nov., M. clariceae sp. nov. and M. lacinia sp. nov. from Madagascar. The males of this genus are easily recognized among the other genera of Pristocerinae by having the antennae very long, about as long as the whole body, a condition unique in Bethylidae. Our findings emphasize the endemicity of the flat wasp fauna of Madagascar and its high potential of biodiversity.
