Holotype, 1♀, China, Hebei, Chahar, Yangkiaping, 21.VII.1937, O. Piel, No. 201105603 (ZJUH). Paratype: 1♀, China, Hebei, Chahar, Yangkiaping, 21.VII.1937, O. Piel, No. 201105604 (ZJUH).
Body length (excluding ovipositor sheath) 16.5 mm. Fore wing length 12.2 mm.
Head. Antennal segments more than 33 (apical segments missing); third segment 1.3 times longer than fourth segment; length of third and fourth segments 4.0 and 3.0 times their width, respectively. Maxillary palp 4-segmented; labial palp 3-segmented; length of maxillary palp 0.7 times height of head. Head in dorsal view 0.6 times as long as wide. Eye 1.3 times as long as temple in dorsal view. Length of malar space equal to basal width of mandible, 0.3 times maximum width of eye. POL: OD: OOL=9: 10: 24. Vertex densely punctate. Temple punctate dorsally, densely reticulate-punctate ventrally. Frons slightly concave, medially almost smooth with some rugae, laterally with oblique striae. Face densely rugose-reticulate, medially with a triangular promience near antennal sockets. Clypeus reticulate-punctate, apical margin with median notch, ventrally with transverse striae.
Mesosoma. Length 1.6 times its height. Pronope deep, slit-shaped. Side of pronotum punctate, antero-medially, subdorsally and posteriorly crenulate, postero-medially almost smooth. Notauli narrow and deep, crenulate, its posterior area with median carina. Scutellum slightly convex and densely punctate, lateral carinae absent, with several striae posteriorly. Prepectal carina complete, weak, laterally obscure. Precoxal sulcus coarsely crenulate, anteriorly rugose-punctate. Metanotum without median carina. Propodeum coarsely rugose-reticulate.
Wings. Fore wing, r: 3-SR: SR1=17: 20: 60. 2-SR: 3-SR: r-m=15: 20: 21. 1-M: m-cu=40: 25. 1-CU1: 2-CU1=10: 51. r-m slightly curved below, without remnant vein. Hind wing, marginal cell widened apically, its apical width 2.5 times minimum width of cell below vein R1. 1-M: 1r-m=20: 14. cu-a inclivous, posteriorly slightly curved towards wing base.
Legs. Length of hind femur, tibia and basitarsus 6.4, 13.7 and 10.7 times their width, respectively. Hind tibia 1.8 times as long as hind femur.
Metasoma. First tergite robust and widened posteriorly, densely rugose, smooth apically, dorsal carinae obscure. Length of first tergite 1.8 times its apical width. Second and following tergites smooth and shinny. Ovipositor sheath twice as long as metasoma, 2.5 times as long as hind tibia, 2.7 times as long as mesosoma, and 1.3 times as long as fore wing.
Colour. Body dark reddish brown. Face, clypeus and mandible yellowish brown. Antennal scapus and pedicel yellowish brown, 8th-14th flagellomeres and palpi yellow. Tegula, metasoma (except first tergite) and legs reddish-brown. Ovipositor sheath dark brown. Pterostigma yellowish brown, veins dark brown to light brown, wing membrane faintly brown.
Body length (excluding ovipositor sheath) 12.8-16.5 mm, fore wing length 10.3-12.2 mm. First tergite dorsal carinae obscure or only visible basally.
This new species is similar to Brulleia flavibasalis He and Chen, but differs in having the frons medially almost smooth with some rugae, laterally with oblique striae (in latter concave medially, with sparse, fine and obsolete punctures laterally); the length of maxillary palp 0.7 times height of head (in latter 0.5 times) and dorsal carinae of first tergite obscure or only visible basally (in latter present in basal half).
The tarsus of left hindleg of holotype missing. Most of the flagellomeres of paratype missing.
After dense punctation of scutellum.
