 Pristaulacus excisus Turner 1922: 271; Hedicke 1939: 7; Smith 2001: 283; Turrisi et al. 2009: 57.   
 Type material examined. VIETNAM: holotype ♀, “Tonkin: Hoabinh., Aug. 1918, R.V. De Salvaza /Indo China, R.V. De Salvaza, 1919-25/ Pristaulacus excisus Turn., Type/Type/ B.M. Type Hym. 3.a.106.” (BMNH).   
 Additional material examined. In the BMNH there is another ♀ not belonging to the type series, having the same data as the holotype.   
 Redescription. FEMALE (holotype). Length: 12.5 mm; fore wing length: 9.1 mm; ovipositor length: 11.6 mm.   
 Colour blackish, except: clypeus extensively dark reddish orange; mandible except base extensively reddish orange, with apex darkened; maxillo-labial complex dark brown; antenna (A1–A3) dark brown; legs reddish brown to dark reddish brown, except coxa II and III dark brown; wing hyaline, extensively brown infuscate in the proximal half, below stigma and at the apex; metasoma dark brown, except apex of T1 and extensively basal half of T2 dark reddish; valvula 3 of ovipositor dark brown. Setae: light brown on head, goldish on mandible, whitish otherwise.   
 Head, from above, 1.3 × wider than long, shiny; occipital margin deeply grooved medially; temple, from above, well-developed, rounded; occipital carina wide, 0.8 × diameter of an ocellus, interrupted medially in the occipital groove; POL:OOL= 1.1; ocellar area 2.0 × wider than long; vertex and temple with fine, superficial and scattered punctures (distance between punctures 5.0 × or more puncture diameters); frons with fine, superficial and scattered punctures (distance between punctures 3.0 × puncture diameters); clypeus with coarse, deep and scattered punctures; malar area with coarse, deep and dense punctures in middle; occipital area with fine, superficial and scattered punctures (distance between punctures 3.0 × puncture diameters); (both antenna broken, partly missing); A3 3.8 × longer than wide; (A4–A5 missing). Setae: erect, short and scattered on vertex and most frons; erect or semi erect, long and scattered on temple (length of setae 0.8–1.0 × diameter of an ocellus); recumbent, long and dense on lower frons and on clypeus; recumbent, long and dense on malar area.   
 Mesosoma coarsely sculptured; pronotum areolate rugose, with one well-developed anterior tooth-like process on each lateroventral margin; propleuron polished and shiny with coarse, deep and dense punctures on most of dorsal surface, very fine, superficial and scattered on ventral surface (distance between punctures 3.0 × puncture diameters); prescutum triangular, not concave, areolate-rugose; mesoscutum transverse-carinate (anterior half) to areolate-rugose (posterior half) with anterior margin only slightly emarginate in middle, rounded (lateral view); notauli deep and wide; scutellum areolate-rugose; mesopleuron areolate-rugose, except subalar area, polished and coarsely and densely punctate; metanotum longitudinally carinate; propodeum areolate-rugose, except anterior margin longitudinally carinate; venter of mesosoma areolate-rugose; fore wing with vein 2-rs+m short (obliterate); coxa I polished, weakly punctate; coxa II transverse-carinate; coxa III transverse-carinate on dorsal surface, polished and punctate on ventral surface, punctures coarse, deep and dense (distance between punctures 1.0–1.5 × puncture diameters); spurs of mid tibia subequal in length; inner spur of hind tibia longer than outer spur; hind basitarsus 9.9 × longer than wide, and 1.0 × as tarsomeres 2–5; tarsal claw with four tooth-like processes. Setae: erect, short and scattered on dorsal surface; erect or semi erect, long and dense on pronotum; recumbent or semi erect, short and dense on sides and venter of mesosoma; erect, long and scattered on hind surface of propodeum; erect, moderately long and dense on propleuron (setae length about 0.5 × pretarsus length).   
 Metasoma pyriform (lateral view), strongly compressed laterally; petiole elongate, slender, 4.3 × longer than wide; segments 1 and 2 polished and shiny; remaining segments with fine, superficial and dense punctures; sculpture of S7 and T8 not well distinguishable; ovipositor 1.3 × longer than fore wing length. Setae: segments 1 and 2 glabrous; recumbent, short and dense on remaining segments.   
MALE unknown.  
 Distribution. Vietnam (Hoa Binh Province), known only from the type locality (Fig. 186).   
 Biology. Unknown.
