The family of Platycnemididae is a species relatively few in number.The researchers can only rely on identification and classification of the morphological features to conduct relevant studies.This paper has overviewed the research history and domestic research status of Platycnemididae,as well as the classification errors or disputes.The paper proposed that Platycnemis pierrati Navas,Copera.tokyoensis Asahina and Platyc-nemis.foliosa Navas is the junior synonym of Copera.marginipes Rambur,Copera.rubripes Navas and Platyc-nemis.foliacea Selys,respectively.The classification of Coeliccia cyanomelas Ris,Coeliccia didyma Selys,and C.sexmaculatus Wang should be promoted for further study.%扇蟌科是蜻蜓目均翅亚目的一个种类相对较少的科，主要依赖形态学特征分类方法进行鉴定分类研究。综述了扇蟌科蜻蜓研究历史和国内研究现状，对文献中提出的分类错误或争议问题进行了归纳整理：Platycnemis pierrati Navas、东京狭扇蟌（ Copera．tokyoensis Asahi-na）和Platycnemis．foliosa Navas分别是黄狭扇蟌（ Copera．marginipes Rambur）、黑狭扇蟌（ Cop-era．rubripes Navas ）和白扇蟌（ Platycnemis．foliacea Selys ）的次定同物异名；黄纹长腹扇蟌（ Coeliccia cyanomelas Ris）、四斑长腹扇蟌（ C．didyma Selys）以及六斑长腹扇蟌（ C．sexmaculatus Wang）分类问题需进一步研究。
