Nine new species of Horismenus Walker (Hymenoptera: Eulophidae) in Brazil, with an emphasis on the fauna of one of the largest tropical forests on the planet, the Atlantic Forest.

Horismenus Walker (Hymenoptera: Eulophidae) is one of the largest genera in Eulophidae, and additional collecting in tropical America will undoubtedly add numerous new species. Here we describe nine new species of Horismenus from material collected in Brazil, mainly in Atlantic Forest remnants: H. amplicavus sp.

A survey for potential biological control agents of Miller (Cactaceae) in Brazil reveals two new species of Walker (Hymenoptera: Eulophidae).

This paper deals with the description of two new species of Horismenus Walker (Hymenoptera: Eulophidae) from Brazil, parasitoids of larvae of Adetus analis (Haldeman) (Coleoptera: Cerambycidae). Both species are similar to Horismenus steirastomae (Girault), a species that also parasitizes cerambycids. Adetus analis is a pest of Sechium edule (Jacq.

Paracrias pluteus (Hymenoptera, Eulophidae) in Brazil: new distribution and host records, and with a new host group for Paracrias.

Bruchines damage agricultural crops and trees, reducing the quantity and quality of the seeds. The aim of this study is to record, for the first time, Paracrias pluteus as a parasitoid on the immature stages of Sennius spodiogaster and Sennius cupreatus on seeds of Melanoxylon brauna in Teixeiras, Minas Gerais State, Brazil. Paracrias pluteus is a parasitoid without previous host records and known only from Costa Rica.
