Dysphaea gloriosa Fraser, 1938

They are similar in the size of D. basitincta, the body robust built and more colourful. Males of the species are deep black with dark orange marking on the thorax and the abdomen. The wings are narrow and long, their colour is amber hyaline and make the wings are brighten in sunlight. The wings usually are folded at rest; particularly they are sometime open as perching above the water. The females are less colourful than the males with their wings are more hyaline.

                               

Their habitats are similar to those of D. bastitincta but D. gloriosa is much more widespread in the country. They have been found at streams or rivers in open secondary forests or lowland areas. They do not live far from their breeding habitats and usually perch on vegetations around streams.

Dysphaea basitincta Martin, 1904

This species was described by R. Martin in 1904 base on specimens collected from Tonkin, Vietnam.

They are medium-large sized damselflies and the heavy body is unicolour shining black. Their elongate wings are dark at haft base and tip.

They live in open opaque rivers with mud and sand bottom layer; the males are active and highly territorial. They fold their wing at rest but many times the clap or open the wings under strong sunlight above the water surface. Mostly the damselflies fly not far from their breeding habitats but some time they fly very high and perch high above on vegetation beside the rivers.
