摘　　要：花绒寄甲Dastarcus helophoroides是重要的天敌昆虫。为深入研究其形态学,在实体显微镜下,对外寄生的花绒寄甲成虫进行形态研究,利用绘图仪绘制形态特征轮廓。花绒寄甲成虫口器(上唇、上颚、下颚、下唇),小盾片,后翅为首次绘制。对其头、前胸、鞘翅(雌雄虫鞘翅端角区)、腹部(雌雄虫腹末腹面)进行了重新描述和绘图。文中附有形态图24幅,研究标本存放于河南科技学院(新乡)昆虫标本馆。本研究对寄甲类昆虫的比较形态学和功能形态学研究有重要参考价值。Dastarcus helophoroides is an important natural enemy.In order to study its morphology further,under stereomicroscope with drawing tube,the adult sketches of ectoparasitoid D.helophoroides were drawn and shaded by stippling traditionally,and the study on adult morphological was carried out.Some features were firstly described,such as the mouthparts(labrum,mandible,maxilla and labium)and scutellum.The hind wing was first drawn.Moreover,head,prothorax,elytra(including apical trigonal zone of both sexes),and abdomen(including apical venter of genital segments of both sexes)were redescribed and illustrated.Twenty-four illustrations are provided and the specimens are deposited in the Insect Museum of Henan Institute of Science and Technology,Xinxiang,Henan,China.This study is beneficial to the related comparative or functional morphology of this unique group.
