ABSTRACT. Lepidopterans visiting the flowers of Stachytarpheta cayennensis (Rich.) Vahl (Verbenaceae) in Atlantic Forest remnants, Minas Gerais, Brazil. The composition and seasonality of the lepidopteran community visiting inflorescences of S. cayennensis at Estação Ambiental de Peti, were analyzed. The visits of 445 lepidopterans belonging to 98 species, distributed in 6 families, were registered. Hesperiidae (81,8%), Pieridae (10,8%), Lycaenidae (3,6%), Nymphalidae (2,2%), Papilionidae (1,3%), and Sesiidae (0,3%). Skippers presented the highest species richness, with 70 species. Only four of these had a relative abundance above 5% (Pyrgus orcus (Stoll, 1780), Pompeius pompeius (Latreille, [1824]), Urbanus dorantes dorantes (Stoll, 1790) and Corticea corticea (Plötz, 1882)). According to Palma classification, two species were common, 12 intermediary and 84 were considered rare. Diversity and evenness value were high (H'= 3.98 and E = 0.87). There was a sharp difference in the composition and abundance of the species throughout the year, attributed mainly to a higher richness and abundance during the rainy season. Accordingly, the similarity between rainy and dry season was relatively low, with 18 common species, 25 present only in the dry season and 93 during the wet season. The period of highest foraging activity corresponded to temperatures between 23 and 32ºC and the highest abundance were registered about 10:00h.KEYWORDS.

Vahl (Verbenaceae) em remanescente de Mata Atlântica, Minas Gerais, Brasil. Foram analisadas a composição e sazonalidade da comunidade de lepidópteros visitantes florais de S. cayennensis na Estação Ambiental de Peti. Registrou-se a visita de 445 lepidópteros pertencentes a 98 espécies, distribuídos em 6 famílias: Hesperiidae (81,8%), Pieridae (10,8%), Lycaenidae (3,6%), Nymphalidae (2,2%), Papilionidae (1,3%) e Sesiidae (0,3%). Os hesperídeos também apresentaram a maior riqueza, com 70 espécies amostradas. Das espécies amostradas, apenas quatro tiveram abundância relativa acima de 5% (Pyrgus orcus (Stoll, 1780), Pompeius pompeius (Latreille, [1824]), Urbanus dorantes dorantes (Stoll, 1790) e Corticea corticea (Plötz, 1882)). De acordo com a classificação de Palma, duas espécies foram comuns, 12 intermediárias e 84 foram consideradas raras. Os valores de diversidade e uniformidade foram altos (H'= 3,98 e E = 0,87). Existe nítida diferença na composição e abundância das espécies ao longo do ano, onde foi observado que a maior riqueza de espécies e número de indivíduos estiveram concentrados na estação chuvosa. A similaridade entre as duas estações foi relativamente baixa, 25 ocorreram na estação seca, 93 na chuvosa e apenas 18 ocorreram nas duas estações. Os lepidópteros apresentaram maior atividade de forrageamento em temperaturas entre 23 e 32 ºC, sendo a maior abundância registradas por volta das 10:00 horas.

ABSTRACT. The Ichneumonidae (Hymenoptera) of the Estação Ecológica of the Universidade Federal de Minas Gerais, Belo Horizonte, with emphasis on the Pimplinae species. In one annual cycle 83,712 insects were captured, of which 2,339 were Ichneumonidae, belonging to 17 subfamilies; they were collected by a Malaise trap placed in a montane semidecidual seasonal forest, inside the campus. Among the collected ichneumonids there were 13 genera and 30 species of Pimplinae, of which Pimpla croceiventris was the most frequent species. The species richness of Pimplinae was greater in the ecological station in Belo Horizonte, MG than in other localities studied.

ABSTRACT. Biodiversity of Ichneumonidae (Hymenoptera) and monitoring of the species of Pimplinae and Poemeniinae from Capao da Imbuia, Curitiba, Parana. The ichneumofauna of Capao da Imbuia was studied during three years of capture, using Malaise traps. 114,469 specimens were captured, of which 3,603 belong to 20 subfamilies of ichneumonids. Pimplinae and Poemeniinae in the wood contains 14 genera and 48 species. In the first sample (1978)(1979), 23 species were captured; in the second (1985-) 986),21 species were obtained, 13 of which had been previously captured, with an addition of eight species. And in the last sample (1995)(1996) , 39 species were obtained, of which 17 had not previously been captured. The dominant species, considering the number of individuals, were:

The taxonomy of Neotropical species of Stauropoctonus is reviewed, with redescriptions of S. bicarinatus and S. excarinatus, the description of four new Brazilian species, S. amazonensis sp. n., S. leotacilioi sp. n., S. michelle sp. n., and S. rectus sp. n., and for the first time with a detailed study of the male genitalia of the genus. Additionally, we provide a key to the world Stauropoctonus species.
