解剖制作瓢甲雄性外生殖器样本，观察了盔唇瓢虫属、食植瓢虫属、整臀瓢虫属、黄菌瓢虫属、褐菌瓢虫属、异斑瓢虫属、异色瓢虫属、小巧瓢虫属、宽柄月瓢虫属、盘瓢虫属10个属的16种瓢甲的雄性外生殖器的特征。结果表明，瓢甲的雄性外生殖器，尤其是弯管、侧叶、中叶等结构的形态特征在种、属间具有明显差异，瓢甲的雄性外生殖器形态多样、结构复杂，具有明显的种间差异，可作为物种鉴定，特别是区分近似种的重要依据。

Samples of male genitalia of lady beetle were dissected and made. The male genitals of 16 species of Lady beetles belonging to 10 genera of Lady beetles， including Chilocorinae， Epilachma， Afissa， Macroilleis， Vibidia， Aiolocaria， Harmonia， Oenopia， Menochilus， Lemnia were observed. The results showed that the morphological characteristics of the male external genitalia of lady beetle， especially the curved tube， lateral lobe and middle lobe， were significantly different among species and genera. The male external genitalia of lady beetle were diverse in morphology and complex in structure， and had obvious interspecific differences， which could be used as an important basis for species identification， especially for identifying similar species.
