摘　　要：目的调查和了解西藏自治区(西藏)蚤类区系与分布状况,为进一步开展西藏地区蚤类区系的研究提供基础。方法以藏东南林芝市为调查研究的空间范围,不同海拔高度农耕区的小型兽类及其寄生蚤作为研究对象,应用大号鼠夹,于2018年10-11月对小型兽类及其体表寄生蚤进行调查取样,所获标本在实验室进行分类和鉴定。结果在该地蚤类区系调查中采获1批古蚤属(Palaeopsylla Wagner,1903)标本,经分类鉴定为海仑古蚤(P.helenae Lewis,1973)、内曲古蚤(P.incurva Jordan,1932)、中突古蚤(P.medimina Xie et Gong,1989)和多棘古蚤(P.polyspina Xie et Gong1989)4种,其中,中突古蚤和多棘古蚤为西藏地区首次发现,为该地区蚤类物种新纪录。该文将这两新纪录种的主要鉴别特征、分布区域、宿主动物及以实物作为凭证标本绘制的头部和生殖腹节图等内容分别进行了记述和报道。此外,对我国古蚤属的地理分布特征进行了讨论。结论迄今,西藏地区所知古蚤属物种数已达7种,其数量约占国内该属物种总数的23%。Objective To investigate and understand the fauna and distribution of fleas in Tibet autonomous region(Tibet),and to provide a basis for further research on the fauna of fleas in Tibet.Methods With Linzhi in southeastern Tibet as the spatial scope of investigation and research,small mammals and their parasitic fleas in farming areas at different altitudes were selected as the research objects.From October to November,2018,large rat traps were used for the investigation and sampling of the small mammals and their parasitic fleas,and the samples were classified and identified in the laboratory.Results A batch of Palaeopsylla Wagner,1903,specimens were collected and identified as P.helena Lewis,1973,P.incurva Jordan,1932,P.medimina Xie et Gong,1989,and P.polyspina Xie et Gong,1989,among which P.medimina and P.polyspina were found for the first time in Tibet,setting a new record for flea species in this region.This article recorded and reported the main identification characteristics,distribution areas,host animals,and the head and genital abdominal segments of the two newly recorded species.In addition,this article discussed the geographical distribution of Palaeopsylla in China.Conclusion Up to now,seven species of Palaeopsylla have been known in Tibet Autonomous Region,accounting for 23%of the total number of species in China.
