Resumen

The genus Labena Cresson is composed of parasitoid wasps that attack wood-boring Coleoptera. In Chile, two species have been recorded, and neither fits into any known Neotropical species-group. We propose two new species-groups: the canelensis group, to include L. canelensis Porter, and the pucon group, to include L. pucon Porter and the newly described L. barrigai sp. nov. In addition, a taxonomic key for all Chilean species is provided.
