Stenomalina gracilis

Genus Stenomalina : The lower edge of the clypeus (face) usually has distinct teeth or is deeply notched in the middle. The antennae are typically inserted at or slightly above the level of the lower eye margins. Like most Pteromalids, the antennae have 13 segments, but in Stenomalina the flagellum is relatively slender and elongated with two ring segments (anelli) and six funicle segments. The neck area of the pronotum has a distinct, sharp ridge (carina) along the front edge. The propodeum (rear thorax) lacks a nucha (a neck-like projection at the back). Stenomalina gracilis : Length 2-3.5mm. Relatively elongate and slender compared to other pteromalids. Typically a brilliant metallic green. The legs often have pale yellow or testaceous (brownish-yellow) sections, the coxae usually match the metallic body color. The marginal vein is significantly longer than the stigmal vein. The anterior margin of clypeus normally with a median tooth and a projection on either side of it. Around 15 UK Stenomalina species, difficult to distinguish.

Endoparasitoid of various Diptera, mainly Agromyzidae, Cecidomyiidae and Chloropidae. The commonest member of the genus. Widespread but rarely recorded.
