( Figs 11–14 ) Type material . Holotype male, CHINA : Hainan Province , Changjiang County , Bawangling Nature Conservation Area , 11.v.1989 , light trap , X.H. Wang ( BDN No. 1431). Etymology . From Latin, tuber , swelling, bulb, referring to the tubercle on the margin of tergite IX. Diagnostic characters. The new species differs from C. nervosus (Meigen) in the banding pattern of the tergites. It can be distinguished from other members of the genus by the unique wing pattern and by the presence of a tubercle on tergite IX. FIGURES 7–10.
