摘　　要：在有瓣蝇类中,多数种类只有雄性的描述,在秽蝇属分类工作中也是一块空白状态,这对于蝇类防治、利用和系统分类学研究都有重要影响。因此,根据斑股秽蝇Coenosia punctifemorata Cuiet Wang,1996的交尾标本进行了补充描述,完善了对雌性鉴定的科学性,提高了该种雌性描述的可靠性,可为上述领域的研究解决亟待解决的问题。文中列出了斑股秽蝇的种类鉴别特征,描述了雌性的外形特征,绘制了腹部和尾器的特征图,并补充了该种雄性的腹部特征图。该种的观察标本保存于沈阳师范大学昆虫研究所。In this paper the female of Coenosia punctifemorata Cui et Wang is found and supplemented and figured.A pair of coital specimens are deposited in the Diptera collection of the Institute of Entomology,Shenyang Normal University（IESNU）.In 1996,only male of Coenosia punctifemorata Cui et Wang was reported,but its coital specimens were collected in 2008.Female of the species herein is recorded and supplemented for the first time.Diagnosis of male： Antenna black,without cone process apically;1＋3 dorsocentral setae,2 proepisternal setae,basal scutellar seta as long as apical scutellar seta,all strong;costa reaching tip of M,lower calypter longer than upper one;coxae,femora and tibiae yellow,mid and hind femora with brown dorsal spots apically,tarsi brown black,pulvilli yellow;hind tibia with av and ad,not parallel;total length of abdominal tergites 7 to 9 nearly equal to length of abdominal tergite 5 in dorsal view.Female： Body length 4.5 mm;genal height about 1/7 of eye height;scutum with faint median and paramedian stripes;mid femur with 1 row of anterior setae in basal 3/5,1 basal pv,1 subbasal pv,1 supermedian pv,and 1 subapical pv,in which the supermedian one long;claws as long as pulvilli or tarsomere 5;abdomen oviform,without dark vitta（Fig.1b）,becoming narrow apically,otherwise characters of figure are similar to those of the male.Specimens examined： a pair of coital specimens,Liupanshan Mountain,2500-2700 m,Ningxia,22.ⅵ.2008,collected by Ming-fu Wang.
