Abstract: The earwig family Anisolabididae (Dermaptera) remains taxonomically challenging due to the generic boundaries being largely defined by overlapping characters derived from male genital morphology. During a faunal survey conducted in the Qixia Mountain Scenic Area in Nanjing City, Jiangsu Province, China, a remarkable new species referable to genus Mongolabis Zacher, 1911 was discovered. The new species, Mongolabis qixiashana sp. nov., is distinguished by its unique male genital structure bearing a distinct rounded process within the groove between the dorsal and ventral membranes of the external parameres, which is an autapomorphic feature not found in any of its congeners or related genera. Although its overall paramere proportions and margins resemble those of Mongolabis, the generic placement of the new species is considered tentative pending a comprehensive phylogenetic reassessment of the family. This finding highlights the persistence of hidden earwig diversity within highly urbanized environments and underscores the need for an integrative revision of Anisolabididae combining morphology and molecular data.

摘要：肥螋科（革翅目）的分类学研究长期以来颇具挑战，这主要源于其属级鉴定特征（尤其雄性生殖器形态）存在大量重叠。在对中国江苏省南京市栖霞山风景区的动物区系调查中，作者发现了一种隶属于芒肥螋属（中文名新拟）的显著新物种，栖霞山芒肥螋Mongolabis qixiashana sp. nov.。该新种的独特之处在于其雄性生殖器结构：阳茎基侧突的背膜与腹膜之间的沟槽内，具一明显的圆形突起。此特征为该物种的独有衍征，未见于同属其他物种或近缘属中。根据雄性生殖器基侧突的比例与边缘特征，作者暂将此新种归入芒肥螋属。本发现揭示了在高度发达的城市环境中仍存在隐藏的生物多样性，并强调了结合形态学与分子证据对肥螋科进行整合分类学修订的必要性。
