The genus Nesaulax Roman, 1914 (Hymenoptera, Braconidae, Braconinae) is reported from China for the first time, and a new species (Nesaulax protuberator Li & van Achterberg, sp. nov.) is described and illustrated. Our pairwise genetic results indicated that four Nesaulax specimens from Thailand, Malaysia, and India in the BOLD system are conspecific with our newly described species. In addition, we report a new synonym: Nesaulax gracilis (Enderlein, 1920) syn. nov. of N. pravivena (Enderlein, 1920). A key to the species of the genus Nesaulax is provided for the first time.
