The subgenus <i>Polynema</i> (<i>Doriclytus</i> Foerster, 1847), characterized by pronounced morphological conservatism, has historical taxonomic challenges due to reliance on external morphological characteristics. This study employed an integrative taxonomic approach, combining morphological and molecular analyses, to investigate <i>P.</i> (<i>Doriclytus</i>) diversity in the Oriental region of China.
