Abstract

In this study, Halysituberosus Dong & Wang, 2017 is treated as a synonym of Allorhynchium van der Vecht, 1963 (syn. nov.). Halysituberosus yingjiangensis Dong & Wang, 2017 is a new synonym of Allorhynchium lugubrinum (Cameron, 1900) (syn. nov.) and Halysituberosus menglianensis Dong & Wang, 2017 is transferred to Allorhynchium as a new combination (comb. nov.). Based on additional COI gene sequencing and morphological characters including genitalia characters, both Allorhynchium diffinis (Giordani Soika, 1986) and Allorhynchium radiatum Li, Barthélémy & Carpenter, 2019 are confirmed to be valid species, and their males of the two species are described for the first time. Allorhynchium quadrimaculatum Gusenleitner, 1997 is newly recorded from China. A key to the Chinese species of Allorhynchium are also updated.
