To answer your question, it is generally not possible to identify Psychodinae from photos. If you find specimens that look different from this, please collect them after you take the picture ;)

Not really. All existing genus keys that exist are mostly outdated or misleading in terms of nomenclature, systematics and/or taxonomy. Genus-level taxonomy in Psychodinae is still very poorly explored, and it is likely to change.
The best is Vaillant's (1971-1983) key in E. Lidner's (ed.)
Die Fliegen Der Palearktischen Region, which unfortunately is rather hard to find. It suffers from many weak points - the names are wrong for several of the genera, and many have been split since his time - but is still better than the other ones.
