摘　　要：描述了产自辽宁北票上园地区黄半吉沟上侏罗统义县组下部膜翅目昆虫化石 1新属新种Sinowestratia communicata gen.et sp.nov.,归入原举腹蜂科 (Praeaulacidae)中的白垩细腹蜂亚科 (Cretocleistogastrinae)。这是原举腹蜂科在我国的首次发现 ,也是白垩细腹蜂亚科在晚侏罗世的首次报道。新化石的发现表明 Cretocleistogastrinae与 Praeaulacinae关系密切 ,而与Anomopterellinae关系较远。Praeaulacidae is an extinct hymenopterous family in the Late Mesozoic, including 3 subfamilies: Praeaulacinae, Anomopterellinae and Cretocleistogastrinae. The preceding 2 subfamilies are present in the Late Jurassic (pre Tithonian) strata of Karatau, South Kazakhstan (Rasnitsyn, 1972,1975,1980,1986,1990a,b) and the third is in the Lower Cretaceous of Russia, Mongolia and Australia (Rasnitsyn, 1975,1980,1986,1999a,b;Jell & Duncan, 1986). From the lower part of the Upper Jurassic Yixian Formation (generally regarded as latest Jurassic in age) at Huangbanjigou Village in the Shangyuan area, Beipiao, Liaoning Province, a new genus and species is described here and referred to the subfamily Cretocleistogastrinae. The Praeaulacidae is discovered in China and Cretocleistogastrinae in the Jurassic Period for the first time.
