Revision of the South American species of Neralsia (Hymenoptera: Figitidae) with the description of eight new species

ABSTRACT

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.

RESUMEN

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.
