ABSTRACT
A new species of Zamischus (Hymenoptera, Cynipoidea, Figitidae) from Brazil. A new species of Zamischus from Brazil is described and diagnosed. The species is closely related to Z. brasiliensis but differs in the morphology of antennae and scutellum. Z. aquilesi sp. nov. was collected via Malaise trapping in a tobacco field in Santa Cruz do Sul, Rio Grande do Sul.

ABSTRACT
Four new species of Alloxysta Förster are described (A. andrewsi Ferrer-Suay & Pujade-Villar n. sp., A. costaricensis Ferrer-Suay & Pujade-Villar n. sp., A. hansoni Pujade-Villar n. sp. and A. luismii Ferrer-Suay n. sp.) from Costa Rica being the first records of this genus in this area. Their morphological features and diagnostic characters are illustrated. We provide a diagnosis of Apocharips hansoni Menke with a detailed description of the radial cell, which expands the characteristics of the genus Apocharips.

Neralsia is a genus of Figitid hymenopterans present in both the Neartic and the Neotropical regions. In this work, material from several museums (including all types of the South American species of Neralsia) was analyzed with light and electron microscopy. The South American species are studied as a whole, reviewing 26 previously cited species and describing eight new species. A key for their identification is included and the characters to differentiate species here considered are illustrated. Rev. Biol. Trop. 56 (2): 795-828. Epub 2008 June 30.
Neralsia es un género de himenópteros de distribución americana, presente tanto en la región Neártica como en la Neotropical. En este trabajo se estudian, usando microscopia de luz y electrónica, las especies sudamericanas en su conjunto, 26 anteriormente citadas y ocho especies nuevas, que se describen aquí formalmente. Se presenta, además, una clave para su identificación; y se ilustran los caracteres que permiten definir las especies consideradas en este estudio.

This work reports the first occurrence of Zaeucoila incompleta (Kieffer) as a parasitóid of Diptera in Brazil. Weekly samples were taken with water traps, five placed at the pastures and five in the nearby native vegetation. These traps were made of yellow buckets measuring 30 cm in diameter and filled with 2l of trap water, 2 ml of detergent and 2 ml of formaldehyde. During the year 1998 thirty five examples of Z. incompleta were collected in April, June and July. These data contribute to the knowledge of parasitoids fauna in Brazil.
Este trabalho relata a primeira ocorrência de Zaeucoila incompleta (Kieffer) como parasitóide de Diptera no Brazil. Semanalmente foram realizadas coletas usando armadilhas de água, cinco foram colocadas nos pastos e cinco na mata. Essas armadilhas constavam de bacias amarelas de aproximadamente 30 cm de diâmetro onde era depositada uma mistura de 2 litros de água, 2 ml de detergente e 2 ml de formol. Durante o ano de 1998 trinta e cinco exemplares de Z. incompleta foram coletados, em abril, junho e julho. Esses dados contribuem para o conhecimento da fauna de parasitóides no Brasil.
