摘　　要：基于对世界柽麦蛾属昆虫外部形态和外生殖器的形态学研究, 选择了66个性状演变系列, 通过PAUP*4b10软件对柽麦蛾属51种昆虫进行了支序系统学分析。分析结果认为 heluanensis 种团并不是一个单系群, 柽麦蛾属被重新作了7个种团的划分。在支序系统学分析的基础上, 柽麦蛾属昆虫的14个地理分布区域等级关系被重建, 显示出古地中海地区复杂的历史, 同时说明在该属分布格局中扩散事件客观存在。Sixty-six character transformation series were selected based on the morphological study of fifty-one species of the genus Ornativalva Gozmny worldwide. The cladistic analysis of fifty-one species was performed using PAUP~*4b10. The result shows that heluanensis-group is not a monophyletic group. Hence the modified partition of seven species-groups was proposed: the heluanensis-group includes O. heluanensis, O. longiductella, O. rufipuncta, O. zonella, O. roseosuffusella; the erubescens-group includes O. levifrons, O. erubescens, O. lilyella, O. aspera, O. pulchella, O. ignota, O. frontella, O. arabica, O. sesostrella; the plicella-group includes O. plicella, O. undella, O. xinjiangensis, O. pharaonis; the tamariciella-group includes O. indica, O. misma, O. serratisignella, O. caecigena, O. macrosignella, O. heligmatodes, O. tamariciella, O. pseudotamariciella, O. kalahariensis, O. sattleri; the plutelliformis-group includes O. triangulella, O. antipyramis, O. singula, O. basistriga, O. plutelliformis, O. grisea, O. sieversi; the cerostomatella-group includes O. acutivalva, O. afghana, O. angulatella, O. cerostomatella, O. cornifrons, O. curvella, O. mixolitha, O. mongolica, O. novicornifrons, O. zhengi, O. zhongningensis; the ornatella-group includes O. ochraceofusca, O. ornatella, O. sinica, O. zepuensis, O. miniscula. Based on the result of the cladistic analysis, the relationships of fourteen areas were derived, which shows that the history of Old Mediterranean Region is complicated. It is also recognized that dispersal is an important process, through which the species of the genus Ornativalva achieved their geographic distribution.
