Enicospilus plicatus – Townes et al. 1961: 276 . Diagnosis Interocellar area reddish brown; clypeus weakly to moderately convex, ventral margin subacute; mandible twisted 70°–80°, outer surface without a diagonal setose groove; fore wing fenestra without any sclerites or with weakly linear proximal and distal sclerites present, vein 2rs&RS strongly sinuous, vein 1m-cu&M strongly sinuous, sometimes with short ramellus, CI = 0.50–0.73.

Remarks In comparison with specimens examined by Gauld & Mitchell (1981) , Vietnamese specimens have more strongly twisted mandibles (60°–80° vs 25°–40°) and shorter fore wings (16.0–21.0 mm vs 19.0– 22.0 mm). Their terminal tergites are entirely reddish brown to blackish. Fig. 61. Enicospilus plicatus ( Brullé, 1846 ) , ♀ (IEBR). a . Habitus. b . Head, frontal view. c . Head, dorsal view. d .
