 Description. Specimen MNHN.F. A43720 (Figs 1–2): Body visible from below, 13.0 mm long (14.5 mm with ovipositor); head 1.2 mm long, 2.0 mm wide; antenna not preserved; thorax 5.5 mm long, 3.0 mm wide; abdomen 5.5 mm long, 2.0 mm wide; ovipositor sheath large, 5 mm long, 1.4 mm wide; ovipositor 1.7 mm long, 0.8 mm wide; six legs visible but poorly preserved. Wings without trace of coloured spots (maybe originally hyaline or uniformly coloured); fore wing 10.5 mm long, 4.0 mm wide, pterostigma brown, rather broad, 2.5 mm long, 0.5 mm wide, with its base 5.5 mm from wing base; subcosta completely fused with R; area between costal margin and R very narrow, 0.2 mm wide; Rs emerging from R 3.3 mm from wing base, with basal portion slightly curved, 1.1 mm long, rather long before its fusion with M; M+Cu basally curved and straight in its distal part; M and Cu separating 3.8 mm from wing base; basal free part of M short, 0.5 mm long; straight Rs+M 0.9 mm long; distal Rs+M forking into Rs and M slightly before 1m-cu; distal part of Rs between Rs+M and 1r-rs straight, 0.6 mm long; 1r-rs 0.6 mm long; 2r-rs 0.4 mm long, emerging from pterostigma in its basal half, 1.0 mm from its base; 2r-m absent but 3r-m clearly present and slightly curved, 0.8 mm long; cell 1R1 elongate, 2.3 mm long, 1.1 mm wide; cell 2R1 0.9 mm long, 0.65 mm wide; cell 3R1 3.0 mm long, 1.0 mm wide; cell Rs(+1Rs2) 2.8 mm long, 0.85 mm wide; cell 1M 1.1 mm long, 0.6 mm wide; cell 2M 2.4 mm long, 1.2 mm wide; crossvein cu-a present just distal of base of free part of M, 0.5 mm long; cell 1Cu 3.5 mm long; cell 2Cu larger and broader than cell 1M, 1.3 mm long, 0.8 mm wide; cell 3Cu 2.8 mm long; crossvein a present at 2.5 mm from wing base; basal part of 2A present; vein 1A fused at apex with vein 2A+3A; cell 1A 2.6 mm long, cell 2A 1.8mm long. Hindwing only partly preserved, probably hyaline or uniformly coloured, with apico-costal part preserved, basal part of Rs very long, 2.0 mm long, distal part of Rs 1.9 mm long, cell R1 closed, 3.8 mm long, 0.6 mm wide; 1r-m 0.6 mm long, basal part of M 1.1 mm long, no crossveins 2r-m or 3r-m.   
 Specimen SMNS 66301 (Figs 4–5): Total body length 10.3 mm (9.44 mm without ovipositor). Head 1.17 mm long, 1.66 mm wide; antennae nearly completely preserved (apart from proximal portion); limits of scape and pedicel indiscernible; first flagellomere 0.69 mm long, 0.20 mm wide; second flagellomere 1.21 mm long, 0.18 mm wide; third flagellomere 1.10 mm long, 0.18 mm wide; limits of remaining flagellomeres not clearly indicated, total number of antennomeres 13 – 15 (Fig. 5). Thorax 2.60 mm long, 1.34 mm wide; metascutellum 0.29 mm long, 0.46 mm wide. Wing venation (Fig. 4) identical to that of specimen MNHN.F. A43720. Abdomen 5.89 mm long, 2.50 mm wide; ovipositor 0.86 mm long, 0.47 mm wide.   
 Specimen SMNS66698 (Figs 6–10): Imprint (SMNS 66698a, Figs 6 – 7) and counterimprint (SMNS 66698b, Figs 8 – 10) preserved. Total body length 11.0 mm. Head 1.52 mm long, 1.66 mm wide, eyes large, ocelli partly preserved in counterimprint (Fig. 9); antennae incompletely preserved; first flagellomere 0.74 mm long, 0.21 mm wide; remaining flagellomeres indiscernible. Posterior limit of thorax indiscernible, thorax 1.96 mm wide. Wing venation identical to that of specimen MNHN.F. A43720 (Figs 7, 10).
