Eight specimens of frilled swamp tree frogs of Genus Kurixalus were collected from Pingle Town, Qionglai County, Chengdu Prefecture, Sichuan Province, China in April to May 2020. Based on morphological and molecular evidence, we describe these specimens as a new species of Kurixalus. Kurixalus silvaenaias sp. Nov., which are similar to K. idiootocus in appearance and phylogenetically are sister to each other, but morphologically the former can be distinguished from K. idiootocus and other congeners by the following combination of characters: body size 29.6-32.9 mm in males; single internal vocal sac; snout obtuse and rounded with no obvious dermal prominence on tip; vomerine teeth present; nuptial pads less developed, present on the base of first finger in males; throat coarsely granulated; tuberculated dorsal and lateral skin; outer metacarpal tubercles present; dorsal surface yellowish brown with a large hourglass shaped dark brown marking and without any green speckles; pair of large symmetrical dark blotches on chest; and abdomen dark purple. The new species is the first record of Kurixalus in Sichuan, China.
