Type material examined. The type material consists of two specimens (both ♀), the holotype (not examined) and the paratype (examined), the latter labelled: “ Paratype / Pristaulacus porcatus Sun & Sheng /Lingshan, Henan, 1999.5.24, M-L. Sheng/ 400–500 m, 1999.5.24 ” ( SFPS) .

Redescription. FEMALE (paratype). Length: 10.3 mm; fore wing length: 7.5 mm; ovipositor length: 8.7 mm.

Colour black, except: clypeus reddish black; mandible extensively dark reddish; maxillo-labial complex dark brown with palpomeres lighter; antenna with A1 light orange and A2 dark reddish; legs mostly reddish orange with coxae and hind femur (except articular parts) and tarsi (except articular base and apical fourth) dark brown and fore tarsus reddish brown; wings hyaline, yellowish with veins orange to light brown and stigma brownish; fore wing with a moderately wide irregular brown spot below stigma (as wide as more than half of stigma length), extended posteriorly to hind margin of cell SM2, and a very small brown spot on apex of cell D2; metasoma with side of T1, most of segment 2 and side of T3 irregularly orange. Setae: mostly whitish, light brown on frons and vertex, partly goldish on mandible.
