Diagnosis. Pterostigma evenly brown throughout; wing membrane hyaline; metacarp shorter than length of pterostigma, its distance from apex of the marginal only weakly shorter than its own length; T2 transverse; T1 with extremely small punctuation, together with further tergites shiny to polished; antennomeres 16–17 cubic to onethird times longer than wide; ocelli forming a rather high triangle, hind imaginary tangent to fore ocellus hardly touching hind two ocelli; disc of mesonotum punctured with faint satin sheen; and two spurs of hind tibia equal in length, nearly as long as hind tibia; and ovipositor sheath two-thirds of hind tibia.
