Genus Euphaea Selys, 1840

Males usually have dark bodies and colorful HW or both wings. In many species these colored wings are also partially iridescent, creating additional flashes of color. Females are mostly dull and simple in wing color, which is usually hyaline but occasionally ochreous. In Vietnam, nine species have been recorded, including two new species, Euphaea saola Phan & Hayashi, sp. nov. and E. sanguinea Kompier & Hayashi, sp. nov., described below.
