ABSTRACT. Survey of the hymenopterous parasitoids (Insecta, Hymenoptera) from the Parque Estadual da Fonte Grande, Vitória, ES, Brazil. Parasitoids Hymenoptera were collected in a trail inside the Parque Estadual da Fonte Grande (20º17'51.7''S; 40º20'13.1''W), located in an area of the Atlantic Forest, during the period of June 2000 to July 2001. A total of 4,595 specimens, belonging to 28 families, have been collected. Braconidae, Eulophidae, and Scelionidae, were the most common families, with relative abundance of 22.5%, 14.32%, and 13.12%, respectively. Sixteen families showed the relative frequency lower than 1%. A preliminary list with 47 genera of some of the families is included.

ABSTRACT. Parasitoid Hymenoptera (Insecta, Hymenoptera) collected in a cotton (Gossypium hirsutum L.) (Malvaceae) plantation at the municipal district of Ribeirão Preto, SP, Brazil. Parasitoid Hymenoptera were collected by using Moericke trap placed in a cotton plantation (Gossypium hirsutum L.) of the variety Delta Pine 90, during the period of February 23 rd to April 3 rd , 2001. A total of 16,166 specimens of parasitoids, belonging to eight superfamilies and 22 families, were collected. Encyrtidae, Trichogrammatidae, Mymaridae and Scelionidae were the most common families, being responsible for 45.14%, 19.11%, 14.33% and 6.57% of the total number of parasitoids collected, respectively. Other eigthteen families showed the relative frequency lower than 5%.

ABSTRACT. Parasitoid Hymenoptera collected in a soybean plantation (Glycine max (L.)) Merril (Fabaceae) at the municipal district of Nuporanga, SP, Brazil. Parasitoid Hymenoptera were collected by using Moericke trap placed in a soybean plantation (Glycine max (L.) Merril) (Fabaceae) of the variety Conquista, during the period of March 24 th to April 7 th , 2000. A total of 4,969 specimens of parasitoids, belonging to seven superfamilies and 15 families, were collected. Scelionidae, Encyrtidae, Aphelinidae and Trichogrammatidae were the most common families, being responsible for 41. 66%, 19.42%, 11.19% and 7.35% of the total number of parasitoids collected, respectively. Other eleven families showed the relative frequency lower than 5%.

Abstract.A new species of Ismarus Haliday (Hymenoptera: Ismaridae) from Brazil is described, illustrated and a key to females of Ismarus of the New World is given. The geographic range of Ismarus gracilis Masner, 1976, is extended about 5,200 km farther to southeast.

Hemerobiidae (Insecta, Neuroptera) is a cosmopolitan clade that comprises about 600 described species distributed into 26 genera. Since the publication of revisions to Hemerobius, Megalomus, Nusalala and Nomerobius, new records have been added in literature and taxonomic modifications have occurred at the genus level. The aim of this study was to update a checklist of Hemerobiidae species from Brazil and of specimens deposited at Coleção de Invertebrados do Instituto Nacional de Pesquisa da Amazônia (INPA), Manaus, Brazil; in order to summarize the geographical data of species in Brazilian states and in the Neotropical Region and to present new distributional data. The INPA collection holds 19 nominal species (55.2% of the all specimens identified at species level) of hemerobiids into eight genera and six subfamilies, mainly from the Neotropical Region; the remaining studied specimens were identified to the genus level. Checklist dos Hemerobiidae (Neuroptera) do Brasil e novos registros de distribuição para a Região Neotropical RESUMOHemerobiidae (Insecta, Neuroptera) é um clado cosmopolita com cerca de 600 espécies descritas e distribuídas em 26 gêneros. Eles são predadores de afídeos, coccídeos e outros insetos de corpo macio. Após a publicação das revisões de Hemerobius, Megalomus, Nusalala e Nomerobius ocorreram modificações taxonômicas em nível de gênero e novos registros de distribuição geográfica. O objetivo deste estudo é produzir uma lista das espécies de Hemerobiidae do Brasil e dos espécimes depositados na Coleção de Invertebrados do Instituto Nacional de Pesquisa da Amazônia (INPA), Manaus, Brasil, de forma a sumarizar os dados geográficos das espécies em estados brasileiros e na Região Neotropical e, apresentar novos dados de distribuição geográfica. No INPA existem 19 espécies nominais de Hemerobiidae (55,2% dos exemplares estudados) de oito gêneros e seis subfamílias; o restante dos espécimes estudados foi identificado em nível genérico. Megalomus marginatus é relatada pela primeira vez para o Brasil e Nusalala dispar para o Equador (Celica). Além disso, dez novos registros para os estados brasileiros são apresentados: dois para Nusalala tessellata e Hemerobius, um para Megalomus impudicus, Notiobiella maculata, Sympherobius ariasi, Megalomus, Nusalala e Sympherobius.
