Allorhynchium van der Vecht, 1963: 57-58. Type species: Vespa argentata Fabricius, 1804, by original designation.

Archancistrocerus Giordani Soika, 1986: 143-146. Type species: Archancistrocerus diffinis Giordani Soika, 1986, by original designation.

Halysituberosus Dong & Wang, 2017: 184. Type species: Halysituberosus menglianensis Dong & Wang, 2017, by original designation (syn. nov.).

Diagnosis.

Anterior face of pronotum without foveae; tegula longer than wide, emarginated apically and not reaching posterior end of parategula; epicnemial carina present; dorsolateral margin of propodeum somewhat rounded and without teeth-like projections; T1 either evenly rounded or rather rectangular in lateral view, in some species T1 with somewhat transverse carina basally; in some species, S2 of male convex, or protruding medially into a transverse crest in lateral view; S7 of male with flat uplifted area or 1-3 teeth; metasoma sessile (Tan et al. 2018).

Notes.

Dong and Wang (2017) established the genus Halysituberosus by the three following characters: apical margin of clypeus widely emarginated (Figs 2, 12), vertex without cephalic foveae, and both S2 and S7 with tubercles in male (Figs 6, 7, 16, 17). After our examination of its type species, it is verified that Halysituberosus Dong & Wang, 2017 belongs to Allorhynchium van der Vecht, and Halysituberosus yingjiangensis Dong & Wang, 2017 is a new synonym of Allorhynchium lugubrinum (Cameron, 1900) and Halysituberosus menglianensis Dong & Wang, 2017 should be transferred to Allorhynchium .
