Genus Dysphaea Selys, 1853

Members of this genus have a largely black and robust body in males and females. Wings almost as long as abdomen and are parallel sided and often distinctly colored in the males. Male anal appendages are black, cerci are twice as long as S10, separated widely at base and hollowed out interiorly in the apical half. Their apices are curved and positioned close or overlapping. The left and right tips of male genital ligula curl greatly. Species of this genus are found at large open streams and rivers. In Vietnam, three species of Dysphaea have been recorded: D. basitincta Martin, 1904 , D. haomiao Hämäläinen, 2012 , and D. gloriosa Fraser, 1938 .
