Diagnosis.

Dong and Wang (2017) reported Halysituberosus yingjiangensis from China (one male). After our examination of the type specimen (Fig. 10), Halysituberosus yingjiangensis Dong & Wang, 2017 is identified to be new synonym of Allorhynchium lugubrinum (Cameron, 1900). It differs from A. quadrimaculatum and other congeners by the combination of the following characters: clypeus rugose-punctate medially, almost yellow (Fig. 12); apex of pronotum with yellow band (Figs 10, 13); tegula reddish brown (Fig. 14); wings pale brown, without purple luster; T1 rather rectangular from lateral view, yellow apical bands of both T1 and T2 medially interrupted (Fig. 15); S2 slightly convex, not protruding medially into a crest in lateral view (Fig. 16); S7 of male with a pair of flat lobe-shaped protuberances (Fig. 17).
