Hello Mihailo,

I am sorry for the errors in my last post. I have a migraine today and i have trouble focusing or even thinking clearly. I meant to type suprasquamal ridge and gena. Linguistically translated as over-calypter ridge. If you move the wing for a better view of the calypters, then you look above the lower calypter (suprasquamal) and follow that ridge-like membrane to the scutellum. I find it easier to start where the scutellum meets the thorax, then follow that usually brownish-orange or amber colored membrane. The hairs will cover the length of this ridge for larvipara.
