Not what I'd call a good paper. We had trouble in the UK with this group a few years back so we all took our material to a workshop (on another subject) to try and figure them out.
I came up with the key in http://micropezid...t=node/235 which I'm a bit embarrassed at nowadays. It seemed to fit the bill and our UK recorders seem to be getting it right now.
I also did an online key at https://identikit...silidae/l/ (select "Reed") but that needs revising a bit more, it'll help eliminate the wrong ones.
Prior to that there was a Van der Goot 1996 paper which I'm trying to get hold of (https://diptera.i...d_id=94254)
As for Fauna Europaea, don't expect that to be current, it might be revised in certain taxonomic areas but I don't think there's much activity in some groups.
For Austria I've had problems locating country checklists, you might be more successful within museums but they've not published lists online.
The best checklist for Austria that I've been able to assemble for Micropezids & Psilidae is at http://www.microp...o/node/321 where you can see I've used a lot of Diptera.info links as evidence (your two have yet to be added)
You've your own Atlas now (see https://diptera.i...d_id=93546) and at least a couple of Austrian dipterists posting on Diptera.info Maybe engaging with the Atlas might help with developing better Austrian checklists

P.S. I'd be grateful for the Lat/Long coordinates of those records (GoogleEarth will do)
