A new species of the genus Multinervis Li & Li, 2013, Multinervis phongdienensissp. nov., is described from two locations in Central Vietnam, Thưa Thien-Hue Province: Bach Ma National Park and Phong Dien District. It represents a second species for the genus and for the fauna of Vietnam, where the type species, M. guangxiensis Li & Li, 2013, has also previously been recorded from Northern Vietnam. Illustrations, a differential diagnosis to distinguish the two Multinervis species and a distribution map are provided. Multinervis phongdienensissp. nov. is characterized by the absence of forewing crossveins in the claval region, the reduced subgenital plates being almost entirely fused, the absence of a subgenital angular projection and the unusual lateral flanges of the male connective.
