Type material. HOLOTYPE ♀. COLOMBIA, Caquetá: Florencia, Vereda San Francisco San Pacho, finca El Recreo, 01°42’24”N, 75°36’36” W, 643 m, 04-18.I.2017, trampa Malaise en cultivo de caña (Saccharum officinarum), Y. Ramos-Pastrana (1♀, LEUA –53647).
New World geographical distribution. Colombia (Caquetá *). (Fig. 91).
Etymology. Of Latin ‘sine’ (= without), ‘carenatum’ (= carinae), the name refers to the propodeum devoid of carinae.

Hosts. Unknown.
Taxonomic notes. Eiphosoma sinecarenatum sp. nov. belongs to the Eiphosoma vitticolle species-group. Among the species that make up this group, the closest species is Eiphosoma laphygmae that presents smooth and polished propodeum, with anterior and present transverse carina; yellow mesoscutellum, completely punctate with two lateral black stripes and a central one that extends from the anterior part to the base of the scutellum; however, E. sinecarenatum sp. nov., has striate propodeum with absence of anterior and posterior transverse carina; mesoscutellum mostly black with two small yellow marks on the front of the notaulus, centrally punctate, lateral lobes weakly punctate on front.
