Jumping Plant Lice (Psylloidea)

Although it's quite old, the main reference I use for these is the RES key to Psylloidea by Hodkinson & White. There's also an RES handbook covering nymphal stages, also by White & Hodkinson. The British Bugs website also has some really good information and photos of many species.

It can be quite difficult to get a good look at the shape of the genal cones on a specimen but this can become easier if you clear the specimen in potassium hydroxide solution first. Sometimes the male parameres are easier to see on a cleared specimen than a dried one and the same applies to the female terminalia - especially, as I have discovered recently, if you need to measure the proctiger as the key demands for some species. I generally get as far as I can with keying it before clearing though, as the process removes other characters such as colour.
