Rapid ecological assessment of wasp fauna (Hymenoptera: Aculeata) of the Serra do Divisor National Park, Acre, Brazil
O Parque Nacional da Serra do Divisor (PNSD), localizado a noroeste do Estado do Acre, é considerado uma das áreas de maior diversidade da Amazônia. A importância de se considerar insetos em programas de conservação tem sido muito enfatizada. Vespas solitárias e sociais são componentes muito importantes dos ecossistemas, devido à posição que ocupam nas redes alimentares. Esse trabalho teve como objetivo realizar uma avaliação ecológica rápida da fauna de vespas do PNSD, para subsidiar a elaboração de um plano de manejo do referido parque. A amostragem foi realizada em 12 sítios de coleta, situados no interior de oito tipologias de vegetação. Os insetos foram coletados através de armadilhas Malaise, as quais foram expostas em todos os sítios por 24 horas, totalizando 288 horas de amostragem. Foram consideradas nas análises vespas das famílias Chalcididae, Eucharitidae, Evaniidae, Mutillidae, Pompilidae, Crabronidae e Vespidae. Ao todo, foram coletados 366 indivíduos distribuídos em 40 gêneros e 85 espécies. Os gêneros Ephuta (Mutillidae), Trypoxylon (Crabronidae) e Conura (Chalcididae) foram os mais ricos em espécies. Os sítios localizados na região norte do PNSD, considerada zona intangível e zona primitiva, foram os mais ricos em espécies. Cerca de 65% das espécies foram exclusivas a um único sítio, o que significa que as amostras possuem pequena similaridade faunística. Algumas espécies coletadas são 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

Revision of the genus Siolicaris Jakobi, 1972, with redescriptions of S. sioli (Noodt, 1963) and S. jakobi (Noodt, 1963) from South America, and S. sandhya (Ranga Reddy, 2001) comb. nov. from India (Copepoda, Harpacticoida, Parastenocarididae)
Recent revision of the family Parastenocarididae has revealed the existence of different monophyletic groups within therepository genus Parastenocaris Kessler, 1913 sensu lato. Here, we redefine the genus Siolicaris Jakobi, 1972, arguingfor its monophyly. All the hitherto known Neotropical species of Siolicaris and also the Indian Siolicaris sandhya (RangaReddy, 2001) comb. nov., which are redescribed herein, share what we consider to be a unique constellation of synapo-morphies: in the female, thoracopod 3 enp is absent; in the male, thoracopod 4 enp is reduced; thoracopod 3 exp is robust,strongly incurved and with a very strong thumb, longer than apophysis; and in both sexes, thoracopod 5 is trapezoidal,with all the setigerous elements inserted on the very distal margin. In addition, the proximal position of furcal setae I–IIItogether with the extreme reduction of seta II and the reduction or complete absence of the proximal-most seta on thora-copod 5 exp are other good indications, justifying the inclusion of Siolicaris within a broader group of Neotropical Paras-tenocarididae. The genus is probably of Gondwanan origin, with its known members distributed in the northern SouthAmerica (Amazonian region) and southeastern India. Parastenocaris digitata Noodt, 1963a is treated here as a synonymof Siolicaris jakobi (Noodt, 1963a). Parastenocaris chelifer Delachaux, 1924 and Parastenocaris xyrophora Noodt & Galhano, 1969 are considered species inquirendae of the genus Siolicaris, pending their detailed redescription.</jats:p
