Halysituberosus menglianensis Dong & Wang, 2017: 184.

Material examined.

Holotype, ♂, China, Yunnan Prov., Puer City, Menglian County, 22°19.746'N, 99°35.049'E, 962 m, 13.VI.1989, Dazhi Dong (KIZ 0101842).

Diagnosis.

Dong and Wang (2017) reported Halysituberosus menglianensis from China (one male). After our examination of the type specimen (Fig. 1), we verify that Halysituberosus menglianensis Dong & Wang, 2017 should be transferred to Allorhynchium, which is a new combination. It differs from A. lugubrinum and other congeners by the combination of the following characters: a yellow square central spot on clypeus (Fig. 2); A13 (Fig. 3) elongate, slightly curved and bent backward beyond the middle of A11; tegula dark black (Figs 4, 5); wings pale brown, without purple luster; T1 rather rectangular from lateral view (Fig. 8); apical bands of both T1 and T2 medially interrupted (Figs 1, 8); S2 of male with a large ridge in the middle (Fig. 6); S7 of male with a pair of triangular teeth (Fig. 7).

Distribution.

China (Yunnan).
