中文摘要：

记述了毛翅目等翅石蛾科2新种,即波缘缺叉等翅石蛾（Chimarra fluctuata）和刺枝合脉等翅石蛾（Gunungiella acanthoclada）。产于河南省的波缘缺叉等翅石蛾（Chimarra fluctuata）与产于浙江天目山的Chimarra senticosa Sun ＆ Malicky相似,但其第8节后缘背面观呈波浪状;第9节侧面观前缘上方强烈向前方凸出呈齿状;肛上附肢下叶由基部向端部逐渐加宽;可与后者相区别。刺枝合脉等翅石蛾（Gunungiella acanthoclada）在合脉等翅石蛾属中雄外生殖器独特,具有如下综合特征区别于该属内的其他成员：第10节背板端缘切入深,呈双叶状,且每叶突端部着生一小的刺突;双叶突下方具一骨化较弱的长突起;具一对细长边缘具齿的突起分别连接在每一下附肢基节的上前侧角处。

英文摘要：

The paper describes 2 new species of Philopotamidae from China ： Chimarrafluctuata n. sp. and Gunungiella acanthoclada n. sp.. Chimarrafluctuate n, sp. from Henan Province, resembles Chimarra senticosa Sun ＆ Malicky, from Mt. Tianmushan in Zhejiang Province, China, in the structure of male genitalia, but can be easily recognized by the following characters： distal margin of segment Ⅷ fluctuated in dorsal view ; upper portion of each anterior margin of segment Ⅸ projecting forth strongly ; and lower lobe of each preanal appendage in lateral view with a narrower base and slight thickened to distal end. Gunungiella acanthoclada n. sp. from Guangdong Province, differs from other members of the genus in following combined characters： segment X constituted of two parts： upper portion with apex excised deeply into two lobes and each lobe with stylus at distal end; lower portion less sclerotized, long, apex slightly concaved, Each basal joint of inferior appendages with long process densely covered with spines at base. The type specimens are deposited in the Insect Museum of Nanjing Agricultural University.
