Female: — Length, 1.50 mm. 



Dark metallic green, the abdominal petiole, legs and antennal scape bright golden 

 yellow, rest of antennae black. Eore wings hyaline; discal cilia not arranged in regular lines;

 laterad at the middle, not short, with a distinct median and fainter lateral carina?. Axilla?
