Allorhynchium van der Vecht, 1963

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 .

Distribution.

Oriental, Australian and Palearctic regions.
