Type material. HOLOTYPE ♀. COLOMBIA, Caquetá: Florencia, Vereda San Francisco San Pacho, finca El Recreo , 01°42’24”N, 75°36’36” W, 643 m, 26.IX.–09.X.2016, trampa Malaise en cultivo de caña ( Saccharum officinarum ), Y. Ramos-Pastrana (1♀, LEUA –53657).

New World geographical distribution. Colombia (Caquetá *). ( Fig. 63 ).

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.
