中文摘要：

属名Iragoides Hering长期被视为Phlossa Walker的同物异名，两者全世界已知12种。通过解剖我国已有的种类，发现它们的外生殖器结构并不相同，两个属的模式种各代表一个类型，因此，本文复用Iragoides Hefing为有效名。奕刺蛾属Phlossn的雄性外生殖器具有刺蛾科的典型结构；雌性外生殖器的囊导管端部多少有些呈螺旋状，囊突1枚呈新月形。奕焰刺蛾属Iragoides的雄性外生殖器在阳茎端基环两侧有膜质小突起或尾端有微刺突；雌性外生殖器有相连的2枚囊突，囊突上有许多微齿突。共整理出中国奕刺蛾属Phlossa4种、焰刺蛾属Iragoides5种，后者包括1新种—线焰刺蛾I.lineofusca Wu et Fang，及1新记录种—别焰刺蛾I.elongata Hefing。编制了两个属已知种的检索表，提供了成虫彩色照片和外生殖器特征图。模式标本保存在中国科学院动物研究所。

英文摘要：

The genus lragoides Hering has been considered as a junior synonym of Phlossa Walker. The both genera contain 12 species together. However, the type species of Phlossa does not accord with that of lragoides in the male and female genitalia. Therefore, the genus name lragoides Hering is available and restored here. In lragoides, the juxta has minute spines in the posterior portion or a pair of membranous processes bearing hair at each side in the male genitalia, and the corpus bursae has two signa which usually are trigonal plates bearing minute spines in the female genitalia. In Phlossa, the juxta is typical, without any spines or processes in the male genitalia, and the corpus bursae has a crescent signum in the female genitalia. Four species of the genus Phlossa Walker and five species of the genus lragoides Hering are recognized from China, including 1. lineofusca, a new species described herein. lragoides elongata Hering is reported for the first time in China. The photographs and the genital illustration of the examined species are given. Keys to the Chinese species of both two genera are provided. The type specimens of the new species are deposited in the Institute of Zoology, Chinese Academy of Sciences, BeiJing, China.
