Abstract

Illustrated descriptions of larvae, pupae and adult genitalia are provided for Eugenysa columbiana (Boheman) in Costa Rica. These represent the first such descriptions for the tribe Eugenysini. Females are reported as exhibiting guarding of larvae and pupae. Male presence with the female and larval group is also described. The distribution range is extended to Peru, and host plant data is recorded. A new character from the spermatheca is presented and its potential usefulness in deducing eugenysine relationships is discussed. /// Se presentan descripciones ilustradas de larvas y pupas y genitalia de adultos para Eugenysa columbiana (Boheman) en Costa Rica que constituyen el primer registo para la tribu. Se reporta el cuidado maternal de larvas y pupas. Se describe también la presencía del macho con la hembra y el grupo de larvas. El rango de distribución se extienda à Peru y se presentan datos de la planta hospedejera. Se presenta un nuevo caracter de la spermateca y se discute uso el potencial para clarificar las relaciones filogeneticas de los escarabajos eugenysines.
