Phoridae (scuttle flies)

I'm yet to do much with this family but there are some good resources available, namely the RES keys by R H L Disney. There's one for the whole family except species in the genus Megaselia and another covering the genus Megaselia. They are well relatively easy to use and well illustrated, and both available as free downloads from the out-of-print handbooks section of the RES website.
