摘　　要：The Asian mayfly species of Habrophlebiodes differ from their North American congeners in male genitalia. Among the 4 known Asian species, H. prorninens Ulmer is unique in longer apical segments of labial palpi, venation of hindwings and pigments of wings. H. gilliesi Peters has thinner and basal 2/3 fused penes. H. zo＇inensis You ＆ Gui has short, wide and half-fused penes, each penis has large apical appendage. In redescription on its nymphs, H. zo＇inensis has more and clearer tracheal branches than those of//. gilliesi, and some deeply forked gills and tracheae, and a paler body than in H. tenella Kang ＆ Yang. This genus is similar to Paraleptophlebia and Neoleptophlebia in nymphs, but can be distinguished by setal tufts on lingua of hypopharynx. The exact relationships between members in Leptophlebiinae await more materials.柔裳蜉属Habrophlebiodes蜉蝣的亚洲种类因两阳茎在端部明显分叉而与北美种类有显著区别。本属在亚洲地区现已知4种,其中出众柔裳蜉H.prominens Ulmer的下唇须末节较长、后翅脉相独特以及翅面着色明显而易识别;吉氏柔裳蜉H.gilliesi Peters阳茎较细,两阳茎叶的基部2/3愈合;紫金柔裳蜉H.zijinensis You&Gui阳茎短粗,两阳茎叶在基部1/2愈合,端部突起也较大。与吉氏柔裳蜉相比,紫金柔裳蜉稚虫的鳃具有多而明显的气管分支;与娇弱柔裳蜉H.tenella Kang&Yang相比,紫金柔裳蜉的鳃分叉较深、气管分支更近基部,体色也较浅。柔裳蜉属稚虫的主要特征与拟细裳蜉属Paraleptophlebia和新细裳蜉属Neoleptophlebia相似,但其中舌叶具细毛簇。本属所在的细裳蜉亚科Leptophlebiinae各属之间的系统发育关系重建需要对更多材料进行更深入的研究。
