Distinguished from other species by the following combination of characters: general body color dark brown to black (Figs
Female (holotype): length, 2.3mm. General body color dark brown to black dorsally, being paler toward head, scape and pedicel, axilla, metanotum, apex of tibiae and tarsi, propodeum and base of first tergite of gaster; entire body lighter ventrally, femora and metasoma slightly darker than the rest; setae on dorsum of mesosoma translucent (Figs
Head 1.3× as broad as high.
Mesosoma with fine, raised, polygonally-reticulate to imbricate-reticulate sculpture on mesoscutum (Figs
Metasoma 1.5× as long as broad. Hypopygium very nearly reaching apex of metasoma; apically with a pair of short lateral processes either side of a wide, shallow, median invagination; with about 6 hypopygial hairs (Fig.
Variation. The length of the female varies between 2.2–2.6 mm. The coloration in some specimens are darker than holotype, otherwise very little variation in material examined.
Male. Similar to female except for following: The length of the male varies 1.7–1.9 mm. General body color and head darker than female (Figs

Two species were previously recorded from Argentina,
Concerning the parasitoidism data, it was not possible to separate the parasitoidism of both species; there were few occasions when the host were found so the rate of parasitoidism is only an estimation and correspond to both species combined: five to eight adults per diapausing
