A new species of Gibbauropoda (G. vietnamica sp. nov.) is discovered and described based on four females and one male from Vietnam. The new species differs from its congeners in having a triangular prolongation of the lateral depression on the dorsal shield, as well as in the setation and sculptural pattern of the dorsal and ventral idiosoma. An updated diagnosis of the genus, accompanied by a new list of known species, is given.
