Abstract

Labena Cresson is a large Gondwanan genus best represented in the Neotropical area. We describe three new species in the Neotropical Labena striata species group: Labena gauldianasp. nov. from Costa Rica and Mexico, Labena yucatanicasp. nov. from Mexico, and Labena iquitosicasp. nov. from Peruvian Amazonia. These species are among the largest and most spectacular Neotropical Ichneumonidae ever collected. We also provide additional descriptive remarks regarding Labena striata Townes and Townes (including intraspecific variation) and an identification key to the six species of the striata group.

Résumé

Le grand genre gondwanien Labena Cresson est surtout bien représenté dans la région néotropicale. Nous décrivons trois espèces nouvelles appartenant au groupe néotropical d'espèces de Labena striata, soit Labena gauldianasp. nov. du Costa Rica et du Mexique, Labena yucatanicasp. nov. du Mexique et Labena iquitosicasp. nov. de l'Amazonie péruvienne. Ces espèces comptent parmi les plus grandes et les plus spectaculaires d'Ichneumonidae néotropicaux jamais récoltées. Nous fournissons aussi des renseignements descriptifs additionnels sur Labena striata Townes et Townes (y compris sur la variation intraspécifique) ainsi qu'une clé d'identification des six espèces du groupe striata.
