Diagnosis. Metacarp about 4× as long as its distance from apex of marginal cell; inner spur of hind tibia markedly longer than outer one; postscutellum with an emargination between its middle point and forwarding-pointing projection, phragma exposed; scutellar sulcus reduced to a fine groove in which there is no obvious foveolation; propodeum shining, punctate anteriorly, rugose posteriorly, two series of ridges converging from either side to nucha, their apices more or less connected by a series of transverse ridges; posterolateral areas weakly and irregularly sculptured; apical part of T1 and T2 densely rugose all over; T3 virtually entirely smooth, shining; T1 not much narrowed towards apex; T2 more nearly triangular; and hind coxa almost yellow.

Male. Similar to female, except for propodeum mostly polished, T2 less rugose and antenna much longer (penultimate antennomere at least 2.3× longer than wide) (Described here for the first time).

Host. Larvae of Pyralidae (new record); Cosmopterigidae , Gracillariidae , Tischeriidae , and Tortricidae ( Yu et al, 2012).

Distribution. China (Guizhou, Jiangsu, Zhejiang) new record; Finland, Netherlands, Norway, U.S. A, United Kingdom.

Note. This species is recorded from China for the first time. Characteristics of the specimens examined here mostly agree with the original species description of Mason (1959) except central basal third of T3 not longitudinally aciculate, at most a little uneven or rough anteriorly, and specimens from Jiangsu bred from pyralids in willow with reddish tergites (2+3).
