(Fig. 11)  
 Description. Female. Length of body (excluding ovipositor sheath) 6.4 mm, of setose part of ovipositor sheath 3.6 mm, of fore wing 4.8 mm.   
Head. Antennal segments 29(+), apical segments missing; length of third segment almost equal to fourth segment; length of third and fourth segments 2.8 and 2.8 times their width, respectively; length of maxillary palp 1.5 times height of head; head in frontal view 0.75 times as long as wide; length of eye in dorsal view 1.5 times temple (Fig. 11 H); length of malar space 1.2 times basal width of mandible and 0.4 times maximum width of eye; POL:OD:OOL = 14:6:20; vertex smooth and shiny; temple densely punctate; occipital carina complete and distinct; frons crest-shaped elevated and rugose-punctate laterally, medio-dorsally smooth and medio-ventrally striate, and medially with a strongly protruding lamelliform protuberance with a small carina from it to anterior ocellus; face coarsely rugose, two carinae present from protuberance to clypeus; clypeus convex, dorsally reticulate-punctate, ventrally smooth.  
Mesosoma. Length 2.2 times its height; pronope deep and wide; side of pronotum punctate, antero-medially crenulate and posteriorly rugose-punctate; notauli shallow, coarsely punctate, without a medial carina posteriorly; scutellar sulcus with one carina; scutellum sparsely punctate, lateral carinae absent; precoxal sulcus wide and shallow, densely reticulate-punctate; mesoscutum punctate and its lobes normally convex; metanotum with a complete median carina; propodeum coarsely rugose-reticulate, baso-laterally finely reticulate-punctate.  
Wings. Fore wing: 3.5 times as long as wide. 1-M curved; pterostigma 3.5 times as long as wide; r:3-SR:SR1 = 10:18:83; 2-SR:3-SR:r-m = 22:18:15; 1-M:m-cu = 36:15; SR1 straight; cu-a inclivous, postfurcal; 1-CU1:2-CU1 = 6:31; r-m inclivous. Hind wing: 1-M: 1r-m=10: 15; cu-a subvertical.  
Legs. Length of fore tarsus 0.6 times fore tibia; length of femur, tibia and basitarsus of hind leg 3.5 (excluding tooth), 7.5 and 5.0 times their width, respectively; hind femur robust and largely rugose ventrally; length of outer and inner hind tibia spur 0.21 and 0.17 times basitarsus, respectively; hind femur robust (Fig. 11 D), rugose ventrally and with a sharp ventral tooth.  
Metasoma. First tergite widened posteriorly, dorsal carinae distinct in basal 0.6 of tergite, between dorsal carinae with deep pits, lateral parts coarsely rugose-punctate (Fig. 11 C); length of first tergite 1.2 times its apical width; second tergite punctate baso-laterally and remainder smooth; length of ovipositor sheath 0.6 times body, 1.2 times metasoma, 1.5 times hind tibia, 1.2 times mesosoma and 0.75 times fore wing.  
Colour. Black; mandible reddish brown medially; palpi, fore and middle legs (except reddish brown coxae), hind trochanter and trochantellus and basal one-third of hind femur yellow; antennal scapus and pedicellus dark reddish brown; following segments yellowish brown; hind tarsus and basal fourth of hind tibia pale yellow; ovipositor sheath dark brown; tegulum and pterostigma brown; wing membrane faintly fumose and most veins dark brown.  
 Male. Unknown.   
 Material examined. Holotype, ♀, China, Zhejiang prov., Anji, Longwang Mt., 25.VI.1996, Baoxin Zhang, No. 963570 (ZJUH).   
 Comparative diagnosis. This new species is similar to H. dentator (Fabricius, 1804), but differs in having the length of eye in dorsal view about 1.5 times longer than temple (length of eye in dorsal view shorter than temple in H. dentator); the dorsal carinae of the first tergite distinctly elevated in basal 0.6 of tergite (dorsal carinae of first tergite weakly developed basally); propodeum coarsely rugose-reticulate and baso-laterally finely reticulatepunctate (propodeum rather weakly sculptured).   
 Host. Unknown.   
 Etymology. The name is derived from “ brachy ” (Greek for “short”) and “ gena ” (Greek for “temple”), because of its very short temple.   
 Distribution. China (Zhejiang).
