This big Fanniid comes from a forest south of Amersfoort, Netherlands. It is about 12 mm long, and the strangest features are two long spines on the katepisternum between coxa 1 and 2, and on the coxa 2 there is a pair of big strong hooks. Look at picture three!.
Can somebody (Nikita?) tell me the species.
Greetings, Gerard

Hey Nikita,
How are you doing? Hope everything is well.
Busy with all the catches from your last trips? :-)
Thanks very much for your answer, do you know the function of these interesting looking spines and hooks?
Would you like to have the specimen?
Greetings,
Gerard

Hi Gerard.
1. Yes, a lot of questions and very few answers. On the other hand a very late spring in Russia this year, nothing to do till today, good spring to write articles.
2. Unknown (as 99% such questions in other cases).
The rare case I know the function is described at:
http://www.dipteradatabase.info/?article=11
hook-like spines on mid coxa present in scalaris, manicata-monilis, melania, atripes.
Both hook-like spines on C2 and stright spines on katepisternum in lustrator, fuscula, vesparia.
3. I have only 1 male of lustrator, more material is very much wellcome!
