After I got a Dr. Asahina's paper on Thai prodasineurids last few years, I've been always wondering what is Prodasineura auricolor like. It said that P. auricolor is similar to P. croconota (from China, Hong Kong, Taiwan and Vietnam) and only one drawing of male's caudal appendages (compare with those of P. croconota) is included. Finally, I found it in Petchabun, a new provincial record!

Male is black with broad orange yellow antehumeral stripes. Ocular stripe is orange yellow.  A pair of yellow juxtaposed triangular spots are on prothorax. Abdomen is black with white basal ring. Dorsum of S-10 and superior appendages are blue. Female is black with narrow antehumeral stripes. Dorsum of S9-10 has blue  unique markings. Anal appendages are also blue.

You can see this species in June-July in mountains of Chiang Mai, Kanchanaburi and Petchabun.
