Yes,
matches well. I wonder why the other one is so different? These are great, by the way.

 
eye patterns??
The first spider photographed may represent an extreme condition (maybe genetic, ontogenetic, or in scientific speak, "I have no idea!" Morphological characters usually fit within a specified range, the unique specimen may push the limits.
For example; species A has 6-12 somethings, while species B has 8-14 somethings. The ones you are looking at have 5, 10, and 15. Geographic variation can provide a clue. An undescribed taxon could really screw things up.
Any of the these images you find to be of little value can be frassed.
I do have a Hobo egg case that should hatch soon, curious to see what they might look like. ;)>.
