First of all I am awfully sorry for late reply because I have to waiting for new sequences.
Thank you very much for your kind suggestion. For your asked me the question, The SK2 to SK9 are not Thai ornamenta but they are Phacaspis mitis of Songkhla province.
The specimens codes SK.7, SK.8, SK.9 are your specimens that you gave me before and other specimens were confirmed by Mr. Abdullah as well.
By the way, as you said the bootstrap between the species are very low. Dr. Singtoe suggested that might be the specimens of Genus Phacaspis were analyzed with ornamenta.
However, those sequences will be confirmed the results using Baysian phylogram again.
