No it is not Coptomnma but a Ceresium or genus very close, I do not remember the name, I will look in my collection that I finally came out of the boxes and it seems to me that I have this Ceresium N Caledonia , I tell you this quickly.
Hi Anders Yes Pseudoceresium sorry! I had not changed the label of determination under my insect. Yes personally I had seen the syntypes (2) and Eduard Vives also at the IRSNB in the Fauvel collection. There are now 8 or 10 years? You could ask for a photo of the type at A Drumont.
