Figs 8–14

Diagnosis. Female. Fully stippled body; pronotum fully punctate; mesopleuron with a diagonal black stripe, central area strongly striate; propodeum with rear transverse carinae present only centrally; scutellum loosely punctate in front only; fore wing with distal region of vein M absent.

Description. Female (Holotype). Fore wing 4.8 mm. Mandible with upper tooth a little longer than the lower, clypeus moderately convex, malar space 0.6 × greater than the basal length of the mandible ( Figs 8–10 ); pronotum fully punctate with epomia weakly elevated; mesoscutum densely punctate, notauli faintly impressed; mesopleuron completely punctate, central area striate ( Figs 8–9 ); sternaulus strongly impressed and punctate; metapleuron completely punctate and pubescent, pleural carina weak and incomplete, submetapleural carina short and deep ( Fig. 9 ); scutellum smooth and polished with some punctures in the anterior area ( Fig. 11 ); propodeum completely puncto-striate, strong and complete anterior transverse carina, posterior transverse carina present only in central area ( Fig. 12 ); hind coxa pubescent ventrally and leathery in appearance, hind tibia with a sharp ventral spine; hind tarsal claw curved and pectinate; first segment of metasoma narrow and smooth, widening posteriorly, other pubescent tergites; ovipositor straight, 1.3 × longer than hind tibia, with an apical notch, pubescent ovipositor sheaths; fore wing completely hyaline, with vein 3 rs -m present; 1 m -cu vein located under the upper extremity of vein 3 rs-m; distal part of vein M absent; vein cu-a vein ending at the base of vein Rs & M ( Fig. 13 ); hind wing with four hamuli.

Coloration. Head yellow with black mark on interocellar area; mesosoma yellow with black marks, mesoscutum with two yellow marks that extend beyond the tegula; scutellum yellow with a black mark in the posterior area; mesopleuron black with a yellow mark over the sternaulus; metapleuron yellow with a diagonal black mark in the central part; propodeum yellow with a broad black mark centrally and lateral markings; fore leg yellow; hind leg blackened and central part of femur reddish, coxa with a large black mark; wings completely hyaline; pterostigma brown.

Male. Similar to the female in structures and coloration, but the scutellum has a black triangle-shaped mark on the front; anterior transverse carina of propodeum inclined upwards.

New World geographical distribution. Colombia (Caquetá *). ( Fig. 14 ).

Etymology. From Latin ‘ inter ’ (= between), ‘ punctum ’ (= puncture), referring to the intensity of punctures on the body.

Habitat. The specimens were collected with Malaise-type flight intersection traps at ground level in secondary forest and sugarcane. The vegetation of the collection site corresponds to the Amazonian lowlands.

Hosts. Unknown.

Taxonomic notes. Eiphosoma interpunctum sp. nov. it belongs to the E. dentator species-group. Among the species that make up this group, the closest is E. dentator , which has the transversal posterior carina of propodeum present; pronotum punctate only in the upper part, this is fully punctate in E. interpunctum sp. nov., and with the punctures denser.
