Description.

Female. Body length: 6.6 mm (Fig. 2A ). Body colour: head dark brown, including scape and pedicel; clypeus honey yellow; mandible honey yellow at base, turning dark brown at apex; palpi light yellow; mesosoma honey yellow, except for pro pleuron, which is slightly darker; fore coxa yellow, trochanter, trochantellus, femur and tibia brown, tarsi yellow; mid and hind legs brown, except mid tarsus, which is yellow; first to sixth metasomal tergites honey yellow, seventh tergite honey yellow anteriorly, turning dark brown distally; eight tergite dark brown; ovipositor sheath dark brown only in basal third, remaining area black; ovipositor dark brown, strongly sclerotized at apex; wings light brown, veins and pterostigma brown; tegula yellow.

Head: clypeus smooth, with a row of setae on its ventral margin and dorsally delimited by carina; face covered with setae inserted into punctations; remainder of head smooth, polished and covered with more widely spaced setae (Fig. 2B-C ); scape and pedicel covered with setae inserted into punctations; antenna with 44 flagellomeres; oral cavity oval, width 1.5 times length of malar space; ocellar-ocular distance three times diameter of lateral ocellus; occipital carina present, poorly marked in dorsal region and not meeting hypostomal carina.

Mesosoma: smooth and polished, almost with no clearly defined carinae (Fig. 2B-C ); pronotum densely setose posterolaterally, pronotal groove smooth and narrow; propleuron with setae over entire surface; mesoscutum covered with setae, notauli smooth and narrow, not converging, finishing before middle of mesoscutum (Fig. 2C ); scutellar disk smooth anteriorly, with setae posteriorly; mesopleuron with a smooth, polished and shallow precoxal sulcus, extending along half of mesopleuron; posteroventral area more setose than remaining part of mesopleuron; venter of mesosoma smooth, polished and with few setae; propodeum and metapleuron setose, propodeal lateral carinae poorly defined (Fig. 2F ).

Wings: fore wing vein r equal to 3RSa; m-cu in line with 2RS; 1cu-a slightly distal to 1M; first subdiscal cell open, 2cu-a absent; hind wing vein M+CU equal to 0.52 length of vein 1M (Fig. 2D ); m-cu vein clearly bifurcate at apex (Fig. 2E ).

Legs: smooth, polished and covered with setae; ventral and lateral areas of coxae more setose than dorsal area; hind coxa with a well defined anteroventral basal tubercle; tibiae and tarsi more setose than femora.

Metasoma: first metasomal tergite with two parallel longitudinal carinae, extending half length of tergite, area between two longitudinal carinae higher than tergite edges; dorsope distinct and deep; basal sternal plate 0.20 length of first tergum; suture between second and third tergites indistinct (Fig. 2F ); remaining part of metasoma smooth and polished; ovipositor length equal to metasoma.

Male.

Unknown.

Variation.

Propleuron yellow to dark brown; fore coxa yellow to brown; clypeus and face smooth to slightly striate; occipital carina even throughout or slightly sinuous laterally; propodeal areola poorly defined to absent.

Distribution.

French Guiana and Brazil (Amazonas and Pará states).

Etymology.

The specific name comes from the Greek leio (= smooth) and soma (= body), in reference to the smooth body of this species.
