Median lobe of mesoscutum (Fig. 4a) distinctly convex, smooth with uniformly long white setae; median portion in posterior with fine longitudinal carinae. Most portion of lateral lobe glabrous. Notauli with fine wrinkles, deep in anterior half and shallow in posterior half. Scutellar sulcus wide, with a high median carina, smooth, 0.3–0.4 × as long as scutellum. Scutellum flat, smooth with uniformly white setae. Metanotum conspicuously concave, with short wrinkles. Upper portion of mesopleuron (Fig. 5a) with obvious wrinkles and white setae, most of median portion glabrous, white setae in posterior area; speculum concave; prepectal carina complete, joining with anterior of mesopleuron; precoxal sulcus distinct with fine crenulate. Propodeum (Fig. 4a) roundly convex, median smooth except for anterior and posterior rugose areas; median carina strong, 0.6 × as long as propodeum, lateral areas of median carina obviously concave with transverse wrinkles.

Wings (Fig. 6). Fore wing (Fig. 6a): length about 3 × as long as its maximum width. Pterostigma 5.3–5.4 × as long as its maximum width. Vein M+CU1 straight; vein r-m present; vein 1-SR+M almost straight; vein r arising behind middle of pterostigma; 2-SR 2.3 × as long as r, 0.7 × as long as 3-SR, 0.5 × as long as SR1, 1.9–2.0 × as long as r-m; 1-CU1 0.3–0.4 × as long as 2-CU1. Hind wing (Fig. 6b): vein M+CU1 almost straight; 1-M 1.1–1.3 × as long as M+CU1; vein SR present; vein 3-M obvious and straight.

Legs (Figs 1, 5b). Hind coxa 1.9–2.0 × as long as wide, smooth with long white setae; hind femur 5.3–5.6 × as long as wide; hind tarsus 0.9 × as long as hind tibia; basitarsus 0.6–0.7 × as long as second-fifth segments combined; second segment of hind tarsus 0.5–0.6 × as long as basitarsus, 1.7–1.8 × as long as fifth segment (without arolium).

Metasoma (Fig. 4b). Length 0.8–0.9 × as long as head and mesosoma combined. Dorsope large, triangular. Apical half of first tergite uniformly convex, with finely striate and transverse sculpture between striae; apical margin with obviously oblique wrinkles; dorsal carinae strong, distinctly converging, length 0.5–0.6 × as long as first tergite; apical width 2.0–2.3 × as long as its basal width; length of first tergite 0.9–1.0 × as long as its apical width. Remaining tergites smooth, with uniformly white setae. Hypopygium large, triangular. Ovipositor sheath 0.6–0.7 × as long as metasoma and 0.3 × as long as fore wing (Fig. 1).

Colour. Dark brown to blackish brown (Fig. 1). Mandible (apically dark brown), palpi, pronotum, legs (but telotarsus and claws dark brown), tegulae and pterostigma brownish yellow; middle lobe of mesoscutum, scutellum and mesopleuron, dark brown with reddish brown pattern; wing membrane subhyaline, veins brown. Alternatively, head (but stemmaticum dark brown), mesosoma (propodeum blackish brown), palpi, legs (telotarsus and claws brown or dark brown), tegula and pterostigma yellowish brown; antenna dark brown; metasoma (but apical tergite yellowish brown) blackish brown. Second-fifth tergites laterally and sixth tergite may be yellowish brown.

Male. Length of body 2.5–3.1 mm, and of fore wing 2.2–3.2 mm. Antennal segments 28–33, length 2.6–4.0 mm. Length of mesosoma 2.0–2.6 × its height. Length of first tergite 1.0–1.2 × as long as its apical width and apical width 1.9–2.0 × as long as its basal width. Head, metasoma and antenna, dark brown; palpi, mesosoma (propodeum brown), legs (telotarsus and claw brown), tegula, pterostigma and veins, yellowish brown. Alternatively, face (median with little reddish brown), mandible (apical black brown), palpi, pronotum, legs (tarsus and claw, brown), tegulae, pterostigma, vein, yellowish brown; antenna (ventral of scope yellowish brown), dark brown; vertex, frons (lateral margin dark reddish brown), temple, scutellar sulcus, precoxal sulcus, dark reddish brown to dark brown; metanotum, propodeum and first tergite, blackish brown or first tergite dark yellowish brown and remaining tergites dark brown.

Setose part of ovipositor sheath about 0.7 × as long as hind tibia (its total length about 1.3 × tibia); clypeus and mesoscutum medially yellowish, with face and mesoscutum laterally dark brown; propodeum with closed, parallel-sided and laterally lamelliform areola, sculptured medio-posteriorly, without semicircular smooth and shiny convex area; notauli present posteriorly (Fig. 4a); mesoscutum finely sculptured medio-posteriorly; vein M+CU of hind wing 0.8–1.0 × as long as vein 1-M; mesoscutum steep anteriorly. This species was described by Belokobylskij (1994) as a subspecies of R. meditator (Haliday). It is treated here as a valid species because the differences in the ovipositor length, the shorter temples, the colour of the clypeus and the mesoscutum and the shape of the propodeal areola indicate that it is a separate species. Colour and shape of the propodeal areola are similar in R. setmus Papp, but the latter species has the head and the mesoscutum entirely brownish yellow, the first tergite largely smooth and a shorter ovipositor sheath.
