Dear Jostein,

I am not sure on the future of the Mycetophylo as originally proposed, I have considered this a bit with Jan. Chris is dedicated, for what I know, to acrocerids now. We should keep on an agenda of having an integrated team, anyway, for a long term study on Mycetophilidae systematics worldwide. I am not any more in administration, so it's slightly better for me now. We maybe could create task forces with different responsibilities—key for the genera, comparative morphology of body parts, molecular studies etc.
Your point is interesting. My understanding is that there is neither R2 or R3 in Sciaroidea. The Protorhyphidae have both, R2+3 and R4, the former originating basal to r-m, the later originating distal to r-m. The recent Anisopodidae have clearly a single branch from Rs before r-m, there is no reason to not interpret it as R2+3. The Bibionidae and the Sciaroidea with branched Rs always have much beyond r-m and there is no reason to not interpret it as R4. Of course this demands that each of the sister-groups (Anisopodidae and Bibionidae+Sciaroidea) have lost a different one of the Rs branches, what is uncommon. But accepting R4 in Anisopodidae or R2+3 in Sciaroidea would demand losing one of the branches anyway and displacing it.
Happy dipterological and personal new year to everybody!

Assunto: Is this group/project dead?

It seems this group died a natural death due to lack of initiatives.
Are we
going to see any progress before we meet again at ICD9? Here is a
small
trigger on the wing terminology again. How to interpret this wing? R2
and R3
as separate veins?
