Abstract: Two new species of the earwig genus Forcipula Bolivar, 1897 (Dermaptera, Labiduridae), F. banauensis sp. nov. and F. ifugaoensis sp. nov., are described from riparian habitats in Banaue, Ifugao Province, Luzon Island, Philippines. Both species are diagnosed and illustrated based on external morphology and male genital structures. A shared diagnostic feature is the absence of an acute spiniform epimerite at the apex of the external paramere, a character rarely observed in the genus. The sympatric occurrence of two congeners at a single locality underscores the underestimated diversity of Dermaptera in the Philippine archipelago and highlights riparian forest systems as important reservoirs of endemic earwig diversity.

摘要：本文描述了采自菲律宾吕宋岛伊富高省巴纳韦（Banaue）河岸带生境中的钳螋属Forcipula Bolivar, 1897两个新种：巴纳韦钳螋Forcipula banauensis sp. nov. 与伊富高钳螋F. ifugaoensis sp. nov.。基于外部形态及雄性外生殖器结构，对二新种进行了鉴别并提供了形态特征图。二者共有的鉴别特征为阳茎基侧突末端缺端部刺突，该特征在钳螋属内极为少见。此两个同属物种在同一地点的同域分布，表明菲律宾群岛革翅目昆虫的多样性被严重低估，同时突显出河岸森林系统是特有蠼螋多样性的重要储库。
