Taxonomic notes. Eiphosoma caqueta sp. nov. belongs to the E. nigrovittatum species-group. Among the species which make up this group, the closest is E. eneke sp. nov. transverse anterior carina barely visible in the central area of propodeum and posterior carina absent; ovipositor straight and short, equal to length of hind tibia; and pronotum with the upper extremity of the epomia strongly elevated. Eiphosoma caqueta sp. nov. has a complete and strong anterior transverse propodeal carina; ovipositor 1.7 × longer than hind tibia; and pronotum with the upper extremity of the epomia slightly elevated.
