Cladomorphus trimariensis sp. nov. é descrita de Três Marias, Minas Gerais. A nova espécie difere de C. phyllinus Gray, 1835 principalmente pelo opérculo e placa micropilar do ovo, ausência de espinhos nas pernas médias e posteriores e pelas projeções distais nos tergos IV e V, que são menos desenvolvidas.

Cladomorphus trimariensis sp. nov., from Três Marias, Minas Gerais, is described and illustrated. The new species is different from C. phyllinus Gray, 1835 mainly for the operculum and micropylar plate of egg, absence of spines on the mid and hind legs, for the preopercular organ and distal projection of terga IV and V, that are less developed.

N. ferruginea sp. nov., is described from Brazil and a key of identification of the species is presented. The new species is from Paraná (São José dos Pinhais, Jundiaí do Sul).

The ichneumofauna of Capão 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 (1985-1986), 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: Pimpla semirufa Brullé, 1846, Pimpla caerulea Brullé, 1846, Neotheronia aff. hespenheidei, Pimpla golbachi (Porter, 1970), Pimpla sumichrasti Cresson, 1874, Flacopimpla sulina Graf & Kumagai, 1997 and Pimpla tomyris Schrottky, 1902.

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.

Flacopimpla was described with one species, F. varelae by Gauld (1991) from Costa Rica (only females, Guanacaste National Park). This genus is recorded for the first time in Brazil and a new species, F. sulina, is described and the distribution in southeast and south of Brazil is mapped (Minas Gerais: Belo Horizonte; Paraná: Telêmaco Borba, Ponta Grossa, Curitiba, Colombo, Antonina).

Jomine, new genus and the new species J. una from South Brazil and J. tagoauna from Rondonia, Brazil, are described.

Epelaspis renatoi sp.n. and E. ketiae sp.n. (Phygadeuontinae, Hemitelini) from Jundiaí do Sul, Fênix, Telêmaco Borba, Ponta Grossa, Colombo, Curitiba, São José dos Pinhais, Morretes (Paraná), Tenente Portela and Quaraí (Rio Grande do Sul) are described.

A new name, Tiphiallen nom.n. is proposed for Allenella Genise, 1992 (Hymenoptera, Tiphiidae), preoccupied by Iredale, 1944 (Mollusca, Gastropoda).
