I suppose it could be Marumba dyras but there couple of more species in this genus very similar to this. M.dyras I think is most common of those.

It seems to be Marumba cristata, but the photo and specimen quality is rather poor. I don't think it is M. dyras. Which part of Thailand does it come from?

Paul is right, M. dyras is generally the commonest species in Thailand, but not always.

Having second look at the forewing lines I agree with Adam’s suggestion.

An indication of size would help (dyras is smaller), and also it would be useful to see the underside. The shape of the forewing doesn't seem right for Marumba dyras as well as the bands.

Yes, I have been checking photos on the web, and have noticed too that the moth is in a poor state, maybe I left it in the relaxing chamber too much. How much time would you recommend for relaxing moths this size?. I'll try to send better photos today including underside (flash made the photo look darker too), and I'll measure it. But identifying the genus has helped me lots. Thank you so much both. I'll post more photos of the rest of Thailand moths I need to identify after the weekend, some of them are in the relaxing chamber right now. I really appreciate the amazing help of experts in this forum.

I could be wrong as the photo quality is not at high but your specimen looks like it is greased. If so acetone bath would help to restore natural colours.

Sphinx are large moths, but I usually keep them in relaxing box no more then 48hrs and then inject them with warm water into thorax near wing joints, wait about 1 to 2 hrs and gently start to manipulate the wings.

Pedro, Please include information about which part of Thailand the specimens come from. Different species and subspecies occur in different parts of the country, and particularly with more difficult groups the locality information really will help in identification. Generally there is a greater difference between taxa of the peninsula and mainland, but also different species occur in western and eastern Thailand. Adam. |

thank you so much for the suggestion about using acetone. I have used it before with beetles, some darken due to body fat exuding. Regarding Thailand area where the moths were collected, I have to ask. I hope to have an answer soon. New images:
underside:
wingspan is 10.63 cmts
Thank you

Location is Chiang Rai. I could not be given a more specific location.

Chiang Rai makes sense, because the specimen looks like ssp. cristata rather than the peninsular subspecies.

Thanks Adam. I've been checking subspecies of M. Cristata, and I think it is M. cristata cristata because the other two belong to different places. P.S. Just noticed you said "ssp.", right, and I think it's female too
