Two new species of Dentridactylus Günther (Orthoptera: Tridactylidae) are described and illustrated: Dentridactylus quadratus sp. nov. and Dentridactylus truncatus sp. nov. The new species represent the first record of the subfamily Dentridactylinae from Colombia and the second record for the Americas. Both come from the south of the country and are readily separated from congeners by their larger body size; D. quadratus sp. nov. is further delimited by the quadrate outline of the epiproct, and D. truncatus sp. nov. by the epiproct with lateral lobes and lateral margin of epiproct not indented. Keys for the identification of species in the Americas are provided.
描述并图示了齿指蝗属（直翅目：三指蝗科）的两个新物种：方齿指蝗Dentridactylus quadratus sp. nov.和截齿指蝗Dentridactylus truncatus sp. nov.。这些新物种是齿指蝗亚科在哥伦比亚的首次记录，也是美洲的第二次记录。二者均来自该国南部，且因其较大的体型易于与同属其他物种区分；方齿指蝗D. quadratus sp. nov.进一步由肛上板的方形轮廓界定，而截齿指蝗D. truncatus sp. nov.则由具侧叶且肛上板侧缘无凹痕的肛上板界定。提供了美洲物种的鉴定检索表。
