The species-rich earwig family Forficulidae remains relatively understudied in China. This study reports a new species of Chelidura Latreille, 1825 (Forficulidae: Anechurinae), Chelidura siguniangshana sp. nov., from central Sichuan Province of China, and provides detailed descriptions and illustrations. Notable characteristics of the new Chelidura species include slender and medially straight forceps, shallow lateral tubercles on the ultimate tergite, elongated genitalia, and slender, asymmetrical parameres in males. In addition, Parachelidura liui gen. et sp. nov. is described based on a male specimen also found in Sichuan Province. The new genus is distinguished by the complete absence of tegmina and wings, coupled with a robust molar-tooth in the basal quarter of the male forceps.
种类丰富的蠼螋科在中国仍相对较少受到研究。本研究报告了采自中国四川省中部的1825年拉特雷尔氏（Latreille）的Chelidura属（蠼螋科：异螋亚科）一新种，即四姑娘山Chelidura siguniangshana sp. nov.，并给出了详细描述及插图。新的Chelidura物种的显著特征包括：尾铗细长且中部笔直、末节背板上有浅的侧瘤、生殖器延长，以及雄性的阳茎基侧突细长且不对称。此外，基于同样在四川省发现的一个雄性标本，描述了新属Parachelidura liui gen. et sp. nov.。该新属的特征是完全没有翅和翅鞘，同时雄性尾铗基部四分之一处有一个粗壮的臼齿。
