- Abstract
The external morphology and development of immature stages of Fidiobia dominica Evans & Peña (Hymenoptera: Platygastridae), a Neotropical solitary endoparasitoid of the eggs of Diaprepes spp. (Coleoptera: Curculionidae), are reported. This species behaves as a solitary idiobiont endoparasitoid. It has a stalked egg and two instars. The first instar is cyclopoid and seven-segmented, whereas the second instar is hymenopteriform and 11-segmented. Mandibulae are conspicuous in both instars. On completion of the larval development, the host egg turns amber transparent, making parasitized eggs easily recognizable. The pupa is exarate. F. dominica is a protandrous species and once emerged, males help females to emerge.
