摘　　要：该文系统回顾和分析了朝鲜叉蚤DoratopsyllacoreanaDarskaya,1949的亚种形态和分类,结果表明:(1)朝鲜叉蚤的亚种♂抱器在长与宽之比上均存在较宽幅度变异,这种变异往往也与制片有关,在通常情况下,标本在薄压和没有薄压的条件下作对比,二者形态有很大差异,因此不能单纯用抱器长与中部宽之比来作为种间分类指标;(2)蚤类可动突与不动突,平时都当作一种“硬部位”来对待,而属于“软部位”诸如阳茎钩突和雌蚤受精囊管等,这些器官在压片时往往方向、形状都会出现差异和偏位。70年代以来,雄蚤阳茎钩突的形状在蚤类种间或种下分类中起到了比较重要的辅助作用,但必须有一个前提,即雄蚤的可动突和不动突是在种间和种下出现差异的情况下才适用;(3)通过所附11篇文献的叙述及附图的比较观察,再辅以有关标本的描绘,作者认为D.coreanasichuanensis与D.coreanacoreana在形态上并无区别;D.jii与D.coreanaaraea也无实质性差别。文后附亚种检索表。This paper is a systematic review and analysis of the morphology and classification of subspecies of the Doratopsylla coreana Darskaya, 1949. Results indicated that : (1) There is a great variation in the ratio between the length and middle width of clasper of the known subspecies of D. coreana Darskaya, 1949. These variations are often related to specimen preparation; usually there is significant difference when they were completely flattened or not. Therefore there is certain disadvantage simply using the ratio as an index for species classification; (2) Usually the movable process and immovable process are treated as “hard structure”, while for “soft structure” such as crochet of aedeagus and duct of spermatheca, when they are pressed during specimen preparation their direction and form may develop difference or deviation. Since 1970s form of the crochet of aedeagus has played an important supplementary role in the identification of flea species and subspecies. But there must be a prerequisite that it really shows the actual difference between the movable process and immovable process of the male flea. Furthermore, the filling status of digestive tract, the pressing direction of the body and other factors may also cause errors in classification; (3) Based on the discriptions of the eleven published papers and the comparison of the figures in them as well as examining the specimens collected by authors ourselves, it is found that there is no difference between the morphology of D. coreana coreana Darskaya, 1949 and D. coreana sichuanensis Wei, Chen et Liu, 1981. Moreover, there is no essential difference between the morphology of D. coreana araea Smit et Rosicky, 1976 and D. jii Xie et Tian, 1991. The same number of the subspecies of Doratopsylla coreana Darskaya, 1949 keeps, i. e, D. coreana coreana (=D. coreana sichuanensis ); D. coreana wissemani; D. coreana araea (= D. jii ); D. coreana jianchuanensis; D. coreana hubeiensis; D. coreana liui (=D. liui).
