Species Name: Libellago lineata
Family: Chlorocyphidae
I have not seen this species in Borneo yet but as I have just taken some photos of this pretty damselfly in Kelantan (Peninsular Malaysia) I decide to feature it in this post.
Photos - Top : Male

Bottom: Female

The male is beautifully marked with yellow-orange and black with white-stockinged legs which it displays during its courtship dance. The female is of a paler and more greenish colour.
I found them in a fast flowing stream in a young oil palm plantation near Gua Musang in Kelantan.
