This very “toothy” fellow is a Magnolia Green Jumper – Lyssomanes viridis. This handsome individual is a male – as evidenced by the considerably lengthened chelicerae and enlarged pedipalps.
Just for comparison, here is a female – notice the difference in the size of the chelicerae
This species is fairly common here in central Virginia; I often find females prowling on the undersides of leaves, presumably in search of prey. Males seem to be far harder to find – it seems like I’ve found 3-4 females on average for every male. But that could just be me…
