中文摘要：【目的】本研究对黯螽的右前翅进行定量分析，探讨将翅脉及翅室用于黯螽属Anabropsis昆虫分类的可行性。【方法】选13种黯螽的右前翅翅脉、脉序进行主成分分析、判别分析和聚类分析。【结果】（1）主成分分析显示，13种黯螽属昆虫的前右翅翅脉差异主要集中在Sc、R、Rs、CuA和A脉；（2）典型变量分析能够将13种昆虫区分开；（3）5类数据的判别分析中，基于翅室测量值数据联合数据集的判别效果较好，而基于翅形态测量值进行判别的正确率最低；（4）在聚类分析中，除了马关黯螽Anabropsis (Pteranabropsis) maguanensis和卡氏黯螽Anabropsis (Pteranabropsis) carli与Carnabropsis亚属聚在一起外，其余各亚属的物种均分别聚在一起，与形态划分结果一致。【结论】翅的形态特征可作为黯螽属分类的辅助依据。
英文摘要：[Aim] To investigate the value of the tegmen for taxonomic research on the genus Anabropsis. [Methods] The right tegmen veins and cells of thirteen Anabropsis species were quantitatively analyzed using principal component analysis (PCA), canonical variable analysis (CVA), discriminant analysis, and cluster analysis. [Results] (1) Principal component analysis showed that differences among the 13 species were mainly in the veins Sc, R, Rs, CuA and A. (2) Canonical variable analysis accurately distinguished all 13 species. (3) Discriminant analysis of five datasets (including the dataset combining wing morphometric data and cell measurement values) was the most discriminant; accuracy of discrimination based on tegmen measurement values was the lowest. (4) Except for Anabropsis (Pteranabropsis) maguanensis and Anabropsis (Pteranabropsis) carli, which clustered with Anabropsis (Carnabropsis), species from each subgenus clustered together, a result consistent with the classical morphological classification. [Conclusion] In summary, the morphological characteristics of the tegmen can serve as auxiliary evidence for the classification of Anabropsis.
