Résumé : Nasutitermes aurantius sp. nov. , is described from Central Panama. The soldier is unique among Central American Nasutitermes by its small size and orange head capsule coloration. The enteric valve armature is also unique among congeners. The new species constitutes the seventh Nasutitermes species in the region for which the soldier is described. We provide a key to all Central American Nasutitermes soldiers. Our phylogenetic reconstructions indicate that N. aurantius sp. nov. is more closely related to the Afrotropical Nasutitermes lujae than to any other Neotropical Nasutitermes .
