Specimens examined. As listed in Dow et al. (2018: 279) . Notes. As noted in Dow et al. (2018: 279 , 281) the paraprocts of male D. hongkongensis possess short, blunt subbasal spurs. Also as noted in Dow et al. (2018: 279) specimens from Hong Kong and South China are very constant in their markings but some variation occurs in the markings of the prothorax and metepisternum of Vietnamese material, which is also larger. Also see the remarks under D. brownelli above. Distribution. China ( Fujian , Guangdong , Guangxi , Hong Kong ) and Vietnam (Ba Vi, Tay Thien) ( Fig. 13 ).
