Cercion yunnanensis Zhu & Han, 2000 : 163 –166, figs. 1–10. syn. nov. Remarks. According to the original description, figures and type locality we believe Coenagrion dorothea is the same species as Paracercion impar . We propose a new combination for Paracercion dorothea ( Fraser, 1924 ) and treat P. impar ( Needham, 1930 ) as a junior synonym of P. dorothea . We discussed the status of Cercion yunnanensis with the late H. Q. Zhu in 2005, and she agreed with us in considering Cercion yunnanensis a junior synonym of Paracercion impar . Thus C. yunnanensis is also a new junior synonym of P. dorothea .
