New World geographical distribution. Colombia (Caquetá *). ( Fig. 49 ).

Etymology. The word “Éneké” comes from the indigenous word Huitoto M+ka, which means wasp; this name is designated in honor of the Huitoto indigenous communities that inhabit a large part of the territory where the type material was collected. The name is considered as a noun in apposition.

Habitat. The specimens were collected with a Malaise and suspendable type flight intersection trap at ground level and canopy in secondary forest and sugarcane cultivation. The vegetation of the collection site corresponds to Amazonian lowland forest.

Hosts. Unknown.

Taxonomic notes. Eiphosoma eneke sp. nov. belongs to the E. nigrovittatum species-group. Among the species that make up this group, the closest is E. caqueta sp. nov. which has a complete anterior of propodeum and posterior transverse carina of propodeum present only centrally, pronotum with upper extremity of epomia slightly elevated, whereas in E. eneke sp. nov. the anterior transverse carina of the propodeum is weak and only present in the central area, and the posterior carina of the propodeum is absent; pronotum with the upper extremity of the epomia strongly elevated; short ovipositor equal to length of hind tibia.
