Thorax with mesonotum (scutum) and scutellum unmodified; postpronotal lobe and laterotergites bare. Wings hyaline to infuscate, mainly around the longitudinal veins; between Sc and R 1 sometimes, there is an inconspicuous dark macula pterostigma-like; between veins R 1 and R 2+3 there is a small and inconspicuous hyaline spot; R S stem vein curved upwards before the bifurcation of the radial sector; distal end of M vein transparent or whitish, covered by a dense microtrichia; cell m 3 closed at wing margin. Legs unmodified, long and slender, tibial spurs 1:2:2. Abdomen slender, with seven to nine visible segments; about as wide as thorax, only slightly tapered posteriorly in males, whereas in females the apical segments are moderately elongate and strongly narrowed posteriorly (ovipositor-like).</p></div>	https://treatment.plazi.org/id/03DA650DFFB8FFF2FF717466FEB05708	Public Domain	No known copyright restrictions apply.
