Abstract

Description

A new and morphologically very distinct species of Pediobius from Costa Rica is described. The new species (P. nishidai) is unique among New World species of Pediobius in having the propodeum elongated and extended backwards (i.e. with an elongated nucha). The entire type series (15 females, two males) was reared from a single prepupa of Epilachna mexicana and it has been concluded that the new Pediobius species is a gregarious endoparasitoid that pupates inside its host. The possible use of this new species as a biological control agent against “the Mexican bean beetle” (E. varivestis) should be tested.
Se describe una nueva especie de Pediobius de Costa Rica. La nueva especie, P. nishidai, es única entre las especies ya descritas en el Nuevo Mundo porque tiene el propodeo alargado y extendido hacia atrás. La serie tipo (15 hembras, dos machos) fue criada entera de una prepupa de Epilachna mexicana. La nueva Pediobius es un endoparasitoide gregario que pupa dentro de su hospedero. Se especula que es posible usar esta nueva especie para el control biológico del escarabajo mexicano del frijol (E. varivestis).
