Antespathius Belokobylskij differs from the nominotypical subgenus Spathius Nees by the loss of the first radiomedial vein of fore wing and the antefurcal position of nervulus of fore wing; from subgenus Ambispathius by the antefurcal position of nervulus, the strongly curved medially mediocubital vein (to anal vein) and the densely transversely aciculate face (Belokobylskij, 1995). Additional important diagnostic characters of this subgenus include: parallel vein (2CUb) not interstitial, basoventral tubercles of the hind coxa absent, metasomal terga behind the petiole densely aciculate, and mediocubital vein (M+CU) distinctly curved toward the anal vein (1-1A) in its distal half (Long & Belokobylskij, 2011).
