UnID Jumping Spider

UnID Jumping Spider
Bellevue, King County, Washington, USA
April 22, 2018
Small brownish jumping spider with symmetric regions of white speckles. One or two shots from a lower angle showed a purplish sheen off the abdomen, and a greenish-purple sheen off top of the head. A safety silk line was laid down behind it but not visible in these images (on molding on a car after returning from park).

I tried searching quite a bit through the guide and online but could not find anything with similar patterns. Perhaps the color and/or speckling are variable, or there is sexual dimorphism (or I simply did not look enough).

Maybe Metaphidippus manni female.

Metaphidippus manni (F)
Was doubtful at first, but after looking closely I certainly see some common traits. Ironically, the last posting for the species in Washington state, since 2013, was a male I found last June.
When I found it last June and posted, and saw how long since the previous posting, I figured it was a less common or just less seen species, but then I found I had a picture of another one prior to that. So either it's not commonly seen and I've just happened on multiple specimens, or there aren't that many people actively posting this this particular set of taxa around here.

It sure would have helped had I managed to take a spot focus on the spider at the time... my detail is completely washed-out.

idea of size?
Larger size would indicate Phidippus, likely borealis, maybe purpuratus. Spider appears badly worn.

Size Estimate
Allowing for a +/- 10-15% deviation to fully account for two levels of error that might be introduced, I estimated 0.119" x 0.059". Given the +/- 10-15% error estimate, I've included too many significant digits, and 0.12 x 0.06 is still pushing it a bit.

Having made one pass at an estimate, I know now I can estimate fairly accurately, probably within +/- 5% based on improved process and what I learned this time, but I'm guessing variation in species size might mean that won't be of much benefit - but let me know.


I would guess

Half an inch or more would indicate Phidippus.
Probably a Phidippus borealis regardless.

I guess the half-inch rules Phidippus sp. out, given this one is a hair shy of 1/8".
