ABSTRACT. Contributions to the knowledge of the Vietnamese Spheciformes fauna are presented. The genus Liris Fabricius consisting of eight species (L. aurulentus (Fabricius, 1787), L. deplanatus (Kohl, 1884), L. difficilis Tsuneki, 1983, L. festinans (F. Smith, 1858), L. laboriosus (F. Smith, 1856), L. larriformis (William, 1928), L. robustoides (William, 1928), and L. subtessellatus (F. Smith, 1856)), Isodontia elsei Hensen, 1991, and I. nigella (F. Smith, 1856) are reported for the first time from Vietnam. Two species of the genus Tachysphex (T. changi Tsuneki, 1967 and T. puncticeps Cameron, 1903), four species of the genus Trypoxylon (T. maculipes Tsuneki, 1979, T. prominens Tsuneki, 1979, T. schmiedeknechtii Kohl, 1906, and T. sextum Tsuneki, 1979) which are omitted in the distributional checklist produced by Pham et al. [2015], and thirteen species of other six genera recorded between 2015 and 2021 are added to a Spheciformes fauna list of Vietnam rising a total of 73 species and subspecies belonging to 3 families, 9 subfamilies, and 24 genera. Keys to species of the genus Liris are also produced.
