I think this is a Dolichomitus imperator. Is it correct?

You'd better said Dolichomitus sp. Because Dolichomitus species cannot be identified on picture....

Yeah - lovely photos ... but in this genus a species can only be determined by examining the ridges on the tip of the ovipositor ... which is either hidden in the sheath or burried 3cm into the wood!! Grin

great photos here! congratulations. Wink

it has 2 filaments... one buried, it is the ovipositor. The other is the ?? What is it the function: protect the ovipositor?

Actually it has 5 - the ovipositor is made out of 3 very thin filaments that are held together but can be moved individually using muscles at the base to create a 'saw' effect at the tip. The other 2 imobile filaments make up 2 halves of the shealth that protect the ovipositor when it isn't being used. The ovipositor is very tough and even hardened with metals at the tip but it contains nerves that sense chemicals released by the host so it needs protection. Smile
