摘　　要：报告了我国花蝇科泉蝇属种团研究,中国泉蝇属分为6个种团,为膝角泉蝇种团Pegomya ackland-group,高山泉蝇种团Pegomya alticola-group,变色泉蝇种团Pegomya versicolor-group,毛笋泉蝇种团Pegomya phyllostachys-group,天仙子泉蝇种团Pegomya hyoscyami-group以及中华泉蝇种团Pegomya chinensis-group,并给出了每个种团的特征及种类。膝角泉蝇种团后气门大形,侧尾叶末端分叉,外枝长于内枝,后阳基侧突具变形毛;高山泉蝇种团翅前鬃缺如,第6背板通常裸,第5腹板侧叶内缘常具隆起,端阳体简单;变色泉蝇种团第五腹板通常宽,肛尾叶端缘通常平,后阳基侧突无明显的毛;毛笋泉蝇种团侧尾叶较长,第5腹板侧叶长,较宽地分开,第6背板裸;天仙子泉蝇种团肛尾叶小,第5腹板单纯,长条形,前胫仅具1个后腹鬃,翅前鬃显然短于后背侧片鬃;中华泉蝇种团侧尾叶后面观具细而长的内枝,其端部几乎与宽大的外枝等齐,外枝基部内缘常具指状或角状突起。This paper reports the groups of Pegomya from China,there are six groups of Pegomya from China,namely Pegomya ackland-group,Pegomya alticola-group,Pegomya versicolor-group,Pegomya phyllostachys-group,Pegomya hyoscyami-group and Pegomya chinensis-group,gives the species and features of the groups.Pegomya ackland-group posterior spiracle big,surstyli with outer terminal process distinctly longer than the narrower inner terminal process,postgonite with deformation setula;Pegomya alticola-group prealar seta obsent,tergita 6 bare,sternite 5 with projection in the inner margins of the processes,distiphallus uniformly;Pegomya versicolor-group sternite 5 broad,apical margin of cerci usually flat,postgonite without hairs;Pegomya phyllostachys-group surstyli long,lateral lobe of sternite 5 long,separate widely,tergita 6 bare;Pegomya hyoscyami-group cerci small,sternite 5 uniformly,long strip-shaped,fore tibia with 1 posteroventral bristles,prealar seta longer than postnotopleural seta distinctly;Pegomya chinensis-group surstyli with fine and long inner terminal process in posterior view,the apical part and the broad outer terminal process in level,the inner margin of outer terminal process with hornlike projections.
