In Vietnam, it is recorded, at least, from Huu Lien Nature Reserve in Lang Son province; Tam Dao National Park in Vinh Phuc Province; Viet Vinh community, Vi Xuyen district and Tay Con Linh Nature Reserve in Ha Giang Province; Ba Vi National Park in Hanoi and, recently, from Xuan Son National Park in Phu Tho Province (Do & al, 2011).
Hämäläinen (2014) transferred Calopteryx coomani to the genus Atrocalopteryx. The other Atrocalopteryx known in Vietnam (North only) are atrocyana, laosica and auco, the latter described in 2014.
