摘　　要：记述采自辽宁、黑龙江和新疆的3个跳小蜂属:卡丽跳小蜂属Charitopus Forster、裂脖跳小蜂属Rhopus Forster和塞克跳小蜂属Sakencyrtus Hayat,均为我国首次记录。共记述4个种,其中卡丽跳小蜂属有1中国新记录种,即暗色卡丽跳小蜂Charitopus obscurus (Erdoes);裂脖跳小蜂属2新种,即短翅裂脖跳小蜂Rhopus brachypterous Xu, sp. nov.和黄色裂脖跳小蜂Rhopus flavus Xu, sp. nov.;塞克跳小蜂属1新种,即长尾塞克跳小蜂Sakencyrtus longicaudus Xu, sp. nov.。This paper presents three encyrtid genera collected from Liaoning, Heilongjiang and Xinjiang, i.e. Charitopus Forster, Rhopus Forster, Sakencyrtus Hayat, which are first recorded from China. Four species in total, among them, Charitopus obscurus (Erdoes) is newly recorded from China, Rhopus brachypterous Xu, sp. nov., Rhopus flavus Xu, sp. nov. and Sakencyrtus longicaudus Xu,sp. nov. are proposed new to science. All the specimens are deposited in the Institute of Applied Entomology, College of Agriculture & Biotechnology, Zhejiang University. 1. Charitopus obscurus (Erdoes, 1946), new record (Figs. 1~3) Host: unknown. Distribution: Liaoning(Fuxin),Heilongjiang (Jingbohu),Xinjiang(Changji). Specimen examined: 1♀,Fuxin, Liaoning Province,20-Ⅶ-1995,LOU Ju-xian,C9506-76;1♂,Jingbohu Heilongjiang Province,16-Ⅷ-1995, LOU Ju-xian,C9506-27;1♂,Maoergou Changji, Xinjiang Vygur Autonornus Region, 02-Ⅶ-1988, WANG Ming. 2. Rhopus brachypterous Xu, sp. nov. (Figs. 4~6) Host: unknown. Distribution: Liaoning(Fuxin). Holotype: ♀, Fuxin(420'N,12136'E), Liaoning Province,27-Ⅶ-1994, LOU Ju-xian, C9505-73。 Diagnosis: The species is similar to Rhopus stepanovi Liao, 1961, but can be distinguished with the latter by: 1)antennal funicular segments dark brown, the latter with the first to third funicular segments brown, the fourth to sixth funicular segments white; 2)antenna with the first funicular segment quadrate, the latter with the first funicular segment longer than wide; 3)fore wings not reach apex of gaster, the latter wit fore wings over apex of gaster. 3. Rhopus flavus Xu, sp. nov. (Figs. 7~8) Host: unknown. Distribution: Liaoning(Dalian)。 Holotype: ♀, Dalian (389'N,12136'E), Liaoning Province,15-Ⅷ-1994, LOU Ju-xian,C9505-105. Diagnosis: The species is similar to Rhopus stepanovi Liao, 1961, but can be distinguished with the latter by: 1)antennal funicular segments dark brown, the latter with the first to third funicular segments brown, the fourth to sixth funicular segments white; 2)head 1.
