NOTES. The type specimens of G. formilis could not be examined but considering the characters mentioned in the key by Alekseev (1995) and the redescription by Zhao et al. (2012) it concerns a melanic form of G. hastator . Gasteruption formilis is morphologically very similar, but G. formilis has the head (as most of the body) dark brown (largely red in typical G. hastator ). Other differences are the more or less transverse sculpture of the mesoscutum and the extend of the depression of the clypeus, but both are variable in examined series from Central Asia.
