Promicrogaster Brues & Richardson 1913

The following, brief description is taken from Mason (1981). Ovipositor long to very long, straight, or sometimes abruptly decurved near apex; the tip always sinuate in a vertical plane; sheath hairy and long, 1.0-2.1 times length of hind tibia. Hypopygium sharply folded and striate medially, very long, often surpassing apex of abdomen; tip of hypopygium in lateral view very acute, the top and bottom converging at 20-30 degree. Tergite I smooth to rugulose, the sides parallel or moderately converging (rarely widening) apically; tergite II of similar sculpture, much wider than long and longer medially than laterally; tergum III sometimes sculptured dorsally; abdomen usually rather long and slim for a microgastrine, but not compressed. Propodeum with or without a median carina or with a median carina posteriorly and a median sharp groove anteriorly, otherwise variously sculptured; metanotum with poorly developed setiferous anterolateral lobes; scutellar disc longer than wide and usually sparsely punctate, the polished lateral lunules large and triangular, leaving only a narrow crenulate groove alongside the scutellar disc; scutum polished and closely set with distinct punctures; sides of pronotum with both dorsal and ventral grooves. Head usually thin anteroposteriorly, the temples almost always strongly receding and narrow; cheeks usually long to very long; clypeus strongly emarginate; mouthparts usually protruding, i.e. galea long and glossa protruding and apically bilobate. Radius curved, very much longer than intercubitus which it meets in a gentle curve, second intercubitus weak and attached to first, thus areolet small or very small, occasionally completely absent; margin of vannal lobe usually strongly concave and hairless but sometimes straight and rarely weakly convex and bearing some hairs; nervellus outwardly concave or straight and meeting the submediella at approximately a right angle.
