Long-jawed Orb Weaver - Tetragnatha versicolor - Female

Size: ~10mm body length
Found this critter clambering around in the long grass. I think this is a female in genus Tetragnatha. Quite a pair of fangs!

I noticed the ventral markings and coloration looked more similar with T. versicolour, but there seems to be a lot of variation so I'm not sure if this is reliable. The epigynum shape also looks like it matches with this:

T. elongata vs. T. versicolor
I've gone through this before... maybe even have comments somewhere, but here is my current explanation T. elongata has longer chelicerae, and a more humped abdomen. However, these are hard to see sometimes unless we have nice shots like yours.
