FIGURE 91. Geographic distribution of Eiphosoma sinecarenatum sp. nov. .Yellow circles represent new records. Coloration. Head yellow with interocellar area with a black mark; mesosoma yellow with black marks, mesoscutellum with two yellow marks in the anterior part of notaulus; scutellum yellow; mesopleuron with two yellow marks and a diagonal black stripe; metapleuron yellow with a black mark in the anterior part; propodeum yellow with a wide central black mark and lateral marks; fore leg yellow; hind legs brown darkened; fore wings completely hyaline, pterostigma black.

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. Habitat. The specimen was collected with Malaise-type flight interception traps at ground level in sugarcane ( Saccharum officinarum ) cultivation. The vegetation of the collection site corresponds to forests of the Andean-Amazonian foothills. 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.
