( Figure 3c,d View Figure 3 )
Diagnosis
Head and body chestnut brown to dark brown, metasoma often somewhat paler, 1.2– 1.6 mm, marginal cell elongate, approximately 3 times as long as wide. The species is most likely to be confused with R. strobigena , from which it can be distinguished by the longer marginal cell and less humped mesonotum, and by the antennae, which are considerably longer in females and with more elongate flagellomeres in males.
Description
Female antenna the same size as body, 13-segmented, scape, pedicel, flagellomeres 1–3 yellow or light brown, flagellomeres 4–13 brown. Flagellomeres subequal in size, F1 slightly shorter. Indistinct club of 7 articles, bearing rhinaria, each not much wider than pre-club flagellomeres, F4 often a transitional shape and colour. Male antenna 1.8× body size, 15-segmented, light brown or brown. Flagellomeres 1 and 2 somewhat paler, flattened on outer side, second flagellomere longer than neighbour articles, moderately curved, with rhinaria on about two-thirds of its extent. Compound eyes and ocelli large.
Mesonotum, smooth, with a few scattered setae, weakly arched. Pronotal plate with lateral bridges, foveae confluent in the middle forming a transverse furrow ( Figure 2c View Figure 2 ).
Scutellar plate elongate, elliptical, flat to slightly convex with a distinct margin and large posterior glandular pit. A few smaller pits present anteriorly, sometimes with a seta in the middle. Foveae of average size and depth. Lateral bars longitudinally striate basally. Dorsal scutellar surface with striation irradiating from scutellar plate ( Figure 6b View Figure 6 ) and running more or less longitudinally, sculpture sometimes irregular near the rim. Dorsal surface with a line of setae along its rim, separated from lateral surface by a carina.
Mesopleural line present as a ridge. Lateral surface of metapleura glabrous, except for 2 or 3 long setae on dorsal region. Anteroventral cavity round, filled with hair ( Figure 1b View Figure 1 ). Surface mostly smooth, sometimes 1 or 2 small ridges arising from posterior margin and running anterodorsally. Posterior margin weakly depressed above ventral callus. Posterior incision of metapleura absent.
Propodeum, more or less pubescent laterally, with tuft of hair behind posteroventral depression on metapleura. Propodeal carinae straight, converging dorsally.
Hairy ring often incomplete dorsally, interruption larger in males. Dense in females, more sparse in males.
Legs yellow, metacoxae elongate, with a small posteroproximal tuft of short hair.
Wings broad, hyaline, pubescent, hair fringe not particularly long. Marginal cell closed, rather deep, elongate, almost 3 times as long as deep, vein 2r sometimes slightly arched, subequal to or slightly shorter than Rs, Rs straight. Venation brown, some accessory veins lightly coloured.

Biology
Specimens collected from end of May to beginning of August. In Sweden, specimens were captured in a meadow along a forest edge. One specimen was collected in a boggy birch grove surrounded by oak. Probably a parasitoid of Chloropidae (Diptera) , like other Rhoptromeris species.
