Remarks. In Lelej’s (2005) catalog, this species was known from China and Thailand only, but according to comments by B. Petersen, the putative male for this species was also found in Laos, Cambodia, Vietnam, and Thailand. Our examination of females of C. guangdongensis from Cambodia and Vietnam supports Petersen’s hypothesis. We aim to describe this male in an upcoming treatment of males from Thailand.
