COMPARISON. New species is closely related to East Palaearctic species C. amurensis Ozerov, 2007 , but is distinguished from this species by colour of scutum and structure of surstyli. C. amurensis has scutum of thorax reddish yellow and longer surstyli ( Fig. 38 View Figs 33–41 ), undoubtedly curved in median part ( Fig. 37 View Figs 33–41 ). New species has scutum of thorax blackish and surstyli short- er and straight ( Figs 79, 80 View Figs 78–86 ).
