description: Key to species of Utetes Foerster sensu stricto from NW China
1 Wing membrane brown; length of body (♂) about 5 mm; vein m-cu of hind wing present; [propodeum with a transverse carina and reticulate; medio-posterior depression of mesoscutum large and deep; hind femur 3.5 × as long as wide; first metasomal tergite 1.4 × as long as wide apically]........................................... U. breviculus Chen & Weng, 2005
– Wing membrane subhyaline, at most fore wing medially weakly infuscate; length of body 2.5–3.5 mm; vein m-cu of hind wing absent; [hind leg (except telotarsus) ivory, pale yellow and/or yellow]............................................ 2
2 Mesoscutum rounded anteriorly, without distinct “shoulders” (Figs 4, 43); malar space 0.5–0.7 × as long as basal width of mandible and with malar suture distinctly to slightly impressed; vein 1-SR of fore wing 0.4–0.5 × vein 1-M; setose part of ovi-
positor sheath 0.2–0.3 × hind tibia; [hind femur 3.9–4.5 × as long as wide; medio–posterior depression of mesoscutum shallower and more or less droplet-shaped].................................................................... 3 – Mesoscutum with sharply protruding “shoulders” (Figs 17, 30, 53, 54); malar space 0.8 × as long as basal width of mandible and flat; vein 1-SR of fore wing 0.6–0.7 × vein 1-M; setose part of ovipositor sheath 0.3–0.8 × hind tibia; [wing membrane subhyaline except near submedial veins; orbita partly orange or chestnut brown]................................... 4
3 Flat and smooth lateral areas of first metasomal tergite wide, about as wide as sculptured medial part (Fig. 5); apex of metasoma (including hypopygium) dark brown; face 1.6–1.8 × as wide as high medially (Fig. 9); precoxal sulcus coarsely crenulate (Fig. 3); ovipositor rather slender (Fig. 12).................................................... U. aharmus sp. n.
– Flat and smooth lateral areas of first metasomal tergite narrow, distinctly narrower than sculptured medial part (Figs 43, 44); apex of metasoma (including hypopygium) brownish yellow (Fig. 48); face about twice as wide as high medially (measured from ventral rim of antennal sockets; Fig. 46); precoxal sulcus finely crenulate (Fig. 42); ovipositor robust (Fig. 48)............................................................................................... U. stenotus sp. n.
4 “Shoulders” in front of notauli less protuberant (Fig. 30); first discal cell of fore wing strongly transverse (its maximum width about 3 × its height medially: Fig. 28); setose part of ovipositor sheath 0.8 × as long as hind tibia; precoxal sulcus largely absent and with only a few crenulae (Fig. 29); medio-posterior depression of mesoscutum shorter and more or less elongate droplet-shaped (Fig. 30).................................................................... U. karsius sp. n.
– “Shoulders” in front of notauli more protuberant (Figs 17, 54); first discal cell of fore wing less transverse (its maximum width about twice its height medially: Figs 15, 52); setose part of ovipositor sheath 0.3–0.6 × as long as hind tibia; precoxal sulcus wide and distinctly crenulate (Figs 16, 53); medio-posterior depression of mesoscutum long and linear (Figs 17, 54)....... 5
5 Setose part of ovipositor sheath 0.3 × as long as hind tibia (Fig. 61); scutellum densely setose posteriorly (Fig. 54); propodeum with short medio-longitudinal carina anteriorly (Fig. 55); precoxal sulcus somewhat wider end pointing posteriorly close to middle coxa (Fig. 53); ♀ with about 38 antennomeres........................................... U. subrosae sp. n.
– Setose part of ovipositor sheath 0.6 × as long as hind tibia (Fig. 24); scutellum sparsely setose posteriorly (Fig. 17); propodeum without short medio–longitudinal carina anteriorly (Fig. 18); precoxal sulcus more elongate and pointing to area in front of middle coxa (Fig. 16); ♀ with about 43 antennomeres........................................ U. elongisulcus sp. n.
