Perilampidae
Sign in to saveThe Perilampidae are a small family within the Chalcidoidea, composed mostly of hyperparasitoids. The family is closely related to the Eucharitidae, Chrysolampidae, and Eutrichosomatidae. As presently defined, six genera are described worldwide. They are often brilliantly metallic (especially blue or green), with robust mesosomae and a small, triangular metasomae. They are generally very strongly sculptured. The prothorax is typically very broad and disc-like, and the labrum is multidigitate, a feature shared with the Eucharitidae.

Euperilampus triangularis Perilampidae es una pequeña familia dentro de Chalcidoidea, compuesta principalmente de hiperparasitoides. La familia está muy emparentada con la familia Eucharitidae. Es posible que esta última haya evolucionado a partir de Perilampidae, en cuyo caso sería parafilética. Si ambas familias se unieran en el futuro, el nombre de Eucharitidae tendría precedencia. En el presente se considera que hay 15 géneros y alrededor de 270 especies distribuidas mundialmente. A menudo son de colores metálicos brillantes (especialmente azul o verde), aunque algunos son negros. Tienen un mesosoma robusto y un metasoma pequeño y triangular (hinchado y bulboso en Philomidinae). Generalmente tienen un fuerte diseño escultural. El protórax es aplanado, con forma de disco; el labro multidigitado, un rasgo compartido con Eucharitidae. Miden de 1.3 a 5.5 mm. Otro rasgo que Eucharitidae y Perilampidae comparten es que el primer estadio larval es un planidio con la función de encontrar a un huésped para parasitar. Es decir que tienen una metamorfosis compleja, llamada hipermetamorfosis. Las especies que son hiperparasitoides se entierran dentro del cuerpo del huésped secundario y bus

The Perilampidae are a small family within the Chalcidoidea, composed mostly of hyperparasitoids. The family is closely related to the Eucharitidae, Chrysolampidae, and Eutrichosomatidae. As presently defined, six genera are described worldwide. They are often brilliantly metallic (especially blue or green), with robust mesosomae and a small, triangular metasomae. They are generally very strongly sculptured. The prothorax is typically very broad and disc-like, and the labrum is multidigitate, a feature shared with the Eucharitidae.
A feature shared by the Eucharitidae, Perilampidae, Chrysolampidae, and Eutrichosomatidae is that the first-instar larvae (called "planidia") are responsible for gaining access to the host, rather than the egg-laying females. Those species which are hyperparasitoids burrow into a secondary host's body and seek out endoparasitoid larvae, such as tachinid flies or ichneumonoid wasps, and attack them.
