伪瘤姬蜂属(Pseudopimpla Habermehl), 1917隶属于膜翅目(Hymenoptera)姬蜂科(Ichneumonidae)瘤姬蜂亚科(Pimplinae)[1, 2]。该属全世界已知5种:西古北区2种:阿尔及利亚伪瘤姬蜂(P. algerica Habermehl, 1917)、点伪瘤姬蜂(P. propodeumpunctata Mazón & Bordera, 2010)[3, 4];东古北区2种:全脊伪瘤姬蜂(P. carinata He & Chen, 1990)、光腰伪瘤姬蜂(P. glabripropodeum He & Chen, 1990[5]);东洋区2种(光腰伪瘤姬蜂P. glabripropodeum He & Chen, 1990)、黑伪瘤姬蜂(P. nigricoxalis Sheng & Sun, 2017[5, 6])。该属世界已知种和中国已知种检索表可参考相关报道[4, 6]。
该属寄主已知为茎蜂科(Cephida)昆虫,包括细角茎蜂(Cephus fumipennis Eversmann, 1847)、单带哈茎蜂(Hartigia agilis Smith, 1874)、黑色哈茎蜂(H. nigra Harris, 1779)、扁简脉茎蜂(Janus compressus Fabricius, 1793)、古氏简脉茎蜂(J. gussakovskii Maa, 1949)[7-10]。
2019~2022年,利用集虫网[11]对四川省林木害虫寄生性天敌姬蜂多样性系统调查过程中,发现了伪瘤姬蜂属在四川省的新分布,并发现1新种:九寨沟伪瘤姬蜂(P. jiuzhaiensis Li & Sun, sp. nov.)。对该属进行了简要叙述,并对新种进行了详细描述,给出了鉴定特征图和世界已知种检索表。研究标本保存于国家林业和草原局生物灾害防控中心昆虫博物馆。
