瘤(虫责)属Tyloperla系Sivec和stark(1988)所建立,模式种是Tylopyge attenuata Wu et Claassen。该属过去一直沿用属名Tylopyge Klapálek 1913,经zwick(1988)证实Tylopyge是纯(虫责)属Paragnetina Klapálek 1907的异名。瘤(虫责)属的种类中至大型,头部有3个单眼,雄性腹部5⒍7节背板未发生特化,第8背板中央有一骨化区,第9背板两侧骨化而中央大部区域膜质且有一小齿带,第10背板分为左右两叶,各有一指状突,基部有一瘤丘。该属已知3种,分布于亚洲南部地区。本文记述了我国广西一新种,模式标本保存在北京农业大学昆虫标本室。
