From CAB ABSTRACTS database, I found:

muscid fly, Limnophora riparia.

These might be good places to start for Limnophora riparia. Some of these
authors presumably subscribe to this list.
For Liancalus, more generally, see below....

Dolichopodidae) from Japan, with description of immature stages and
biological notes.

> Most of our British Limnophoras seem to be found near fast-flowing

> stages of blackflies. We also have a large and rather splendid
> Dolichopodid

> etc.
