Hi every body

I have one specimen but I can not recognize it is N. fuscus or N. delicatus. They look very similar. Who can help me and pointing the different character from them.

Thank you

Oh yes both your specimens are fuscus NOT delicatus

see image of my N. fuscus (black form on the left) and brochieri from Myanmar on the right which is closer to delicatus.
