    A synonymyc catalogue for the species of Neotropical Crabronidae and Sphecidae is presented, including all synonyms, geographical distribution and pertinent references. The catalogue includes 152 genera and 1834 species (1640 spp. in Crabronidae, 194 spp. in Sphecidae), plus 190 species recorded from Nearctic Mexico (168 spp. in Crabronidae, 22 spp. in Sphecidae). The former Sphecidae (sensu Menke, 1997 and auct.) is divided in two families: Crabronidae (Astatinae, Bembicinae, Crabroninae, Pemphredoninae and Philanthinae) and Sphecidae (Ampulicinae and Sphecinae). The following subspecies are elevated to species: Podium aureosericeum Kohl, 1902; Podium bugabense Cameron, 1888. New names are proposed for the following junior homonyms: Cerceris modica new name for Cerceris modesta Smith, 1873, non Smith, 1856; Liris formosus new name for Liris bellus Rohwer, 1911, non Lepeletier, 1845; Liris inca new name for Liris peruanus BrĂšthes, 1926 non BrĂšthes, 1924; and Trypoxylon guassu new name for Trypoxylon majus Richards, 1934 non Trypoxylon figulus var. majus Kohl, 1883

    The males of Trypoxylon scrobiferum Richards and T. anapaike Amarante are described for the first time and their genitalia illustrated. These species are demonstrated to represent a monophyletic group, and the scrobiferum species group is established for them. The scrobiferum species group is assigned to the subgenus Trypoxylon. This represents a new subgeneric combination for T. scrobiferum Richards.Os machos previamente desconhecidos de Trypoxylon scrobiferum Richards e Trypoxylon anapaike Amarante sĂŁo descritos e a sua genitĂĄlia ilustrada. Ambas espĂ©cies sĂŁo transferidas do subgĂȘnero Trypargilum para o subgĂȘnero Trypoxylon, incluĂ­das em um novo grupo de espĂ©cies, grupo scrobiferum, aqui criado para abrigĂĄ-las

    O Parque Nacional da Serra do Divisor (PNSD), localizado a noroeste do Estado do Acre, Ă© considerado uma das ĂĄreas de maior diversidade da AmazĂŽnia. A importĂąncia de se considerar insetos em programas de conservação tem sido muito enfatizada. Vespas solitĂĄrias e sociais sĂŁo componentes muito importantes dos ecossistemas, devido Ă  posição que ocupam nas redes alimentares. Esse trabalho teve como objetivo realizar uma avaliação ecolĂłgica rĂĄpida da fauna de vespas do PNSD, para subsidiar a elaboração de um plano de manejo do referido parque. A amostragem foi realizada em 12 sĂ­tios de coleta, situados no interior de oito tipologias de vegetação. Os insetos foram coletados atravĂ©s de armadilhas Malaise, as quais foram expostas em todos os sĂ­tios por 24 horas, totalizando 288 horas de amostragem. Foram consideradas nas anĂĄlises vespas das famĂ­lias Chalcididae, Eucharitidae, Evaniidae, Mutillidae, Pompilidae, Crabronidae e Vespidae. Ao todo, foram coletados 366 indivĂ­duos distribuĂ­dos em 40 gĂȘneros e 85 espĂ©cies. Os gĂȘneros Ephuta (Mutillidae), Trypoxylon (Crabronidae) e Conura (Chalcididae) foram os mais ricos em espĂ©cies. Os sĂ­tios localizados na regiĂŁo norte do PNSD, considerada zona intangĂ­vel e zona primitiva, foram os mais ricos em espĂ©cies. Cerca de 65% das espĂ©cies foram exclusivas a um Ășnico sĂ­tio, o que significa que as amostras possuem pequena similaridade faunĂ­stica. Algumas espĂ©cies coletadas sĂŁo consideradas raras.The Serra do Divisor National Park (PNSD), located at the northwest of Acre State, Amazonia, is considered an area of great biodiversity. The question of considering insects in conservation programs. Solitary and social wasps are important components of the terrestrial ecosystems due to their position in trophic webs. The present study aimed at making a rapid ecological assessment of the wasps from the PNSD in order to support the elaboration of a conservation and management plan for that park. The insects were sampled in 12 sites located in eight forest types by Malaise traps that operated in each for 24 hours, totaling 288 hours of sampling. The results on the families Chalcididae, Eucharitidae, Evaniidae, Mutillidae, Pompilidae, Crabronidae and Vespidae are presented here. On the whole, 366 wasps were collected representing 40 genera and 85 species. The genera Ephuta (Mutillidae), Trypoxylon (Crabronidae) and Conura (Chalcididae) were the most specious. The sites situated at the northern region of the PNSD, the intangible and primitive zones, were the most species rich. Some collected species were considered rare and about 65% of species were exclusive to only one site. This means that the samples have little faunal similarity.Fundação S.O.S
