Yellow circles represent new records and red represent previous records. Etymology. In tribute to the parents of the main author Rubén Cuéllar Castaño and Milley Ramírez Godoy, for unconditional support in all processes. The name must be considered as a noun in apposition. Habitat. The specimen was collected with Malaise-type flight interception trap at ground level in cultivated sugarcane. The vegetation of the collection site corresponds to forests of the Andean-Amazonian foothills. Hosts. Unknown. Taxonomic notes. Eiphosoma rumi sp. nov. belongs to the E. nigrovittatum species-group. The species closest is E. bogan having a mostly black mesosoma, and the posterior carina of propodeum absent; but in E. rumi sp. nov. the face is completely yellow except for the interocellar area; scutellum yellow with a black mark in the posterior area and with an elevated lateral longitudinal carina; mesoscutellum black, with two yellow marks on the lateral lobes in the anterior part of notaulus; fore wing completely hyaline to apex, while E. bogan has a black stripe in the central area of the face attached to the interocellar mark; scutellum and mesoscutum completely black; fore wing with darkened apex.
