Anteromesuscutum coarsely and densely punctate, scutellar disc sparsely and shallowly punctate. Mesopleuron mostly smooth, with coarse punctures on anterior margin (and a bit dorsally); metapleuron smooth on anterior 0.6, with punctures on posterior 0.4. T1 widening towards apex, its posterior margin not straight, sinuate; T2 posterior margin slightly concave centrally; T1-T2 coarsely sculptured, T3 with anterior 0.1-0.2 sculptured, rest smooth, T4+ smooth; T2 separate from T3 by relatively deep, crenulate sulcus. Vein r arising centrally from pterostigma and very slightly inclined forward.
[Additional Note: The description provided by Papp (1987, part X of European ‘Apanteles’) is a bit misleading about the shape of T1].
