Noguchiphaea yoshikoae Asahina, 1976

Asahina (1976) described a new calopterygid genus Noguchiphaea based on two male specimens of N. yoshikoae Asahina, 1976 from Doi Inthanon in Chiang Mai Province in the northern part of Thailand. Subsequently Asahina (1981) described the female of this species, which was collected in the same area - Doi Suthep in Chiang Mai - as the type, and provided additional characters for the genus. In a third paper, Asahina (1985) described further characters of both sexes and considered N. yoshikoae as endemic to Thailand.

Recently, the species has been found in north of Vietnam, Tam Dao National Park and Xuan Son National Park. This is a small-medium sized damselfly; the head and body are metallic green with cream-yellow patches on lower synthorax. As well as it of the female, the male prothorax has distinct structure dorsal posterior lobe. The inferior anal appendages are undeveloped in the male. The wings are hyaline with apical fade spot and both fore and hind wings are petiolate at very base. They fly in the end of rain season in good forests of high mountains and do not live far from the breeding sites. They are weak flying insects and usually perch on vegetations near clean running water.
