I think that it is a female. However, how can you arrive at magnicornis when hairs on the mesonotum are not restricted to the anterior part? i see hairs scattered around the mesonotum. If this is magnicornis, then these keys are a bit misleading. I say that because hairs should not be found beyond the anterior area and 'covered' means there are absolutley no spaces without a hair. I have used Grichanov's keys for Dolichopus and i find the keys to be a delight. Thus, i think that magnicornis is not correct. I see a large structure at the tip of the abdomen. Is this not a hypopygium?

I diagree with both of the following entries"
"Mesonotum entirely covered with hairs in addition to setae" - diaphana and hoffmeisteri
"Only anterior part of mesonotum covered with hairs in addition to setae" - magnicornis and setimana

So if this isn't a match, then shouldn't we back up and start over?

I think that the problem is the following key:
"2. Males: hypopygium present...3
– Females: hypopygium absent...19"

I guess my logic is that if a female has a hypopygium, then follow the key to number 3. Perhaps that is not correct but i see hairs beyond the anterior part of the mesonotum and i cannot agree that the mesonotum is 'covered' with hairs.

Perhaps we can find an email address for Grichanov and ask him about it.
