"Cheiracanthium are distinguished from the closely related species of Clubiona by lacking a conspicuous dorsal groove in the midline of the carapace, the lack of a cluster of long curved erect setae at the anterior end of the abdomen, by having the first pair of legs the longest, and by having a long, pointed spur extending back from the cymbium over the tibia. Species of Cheiracanthium are also chracterised by having relatively thinner legs and more robust bodies than Clubiona." From article by Jørgen Lissner seen here.
