This is a small but colorful jumping spider. Elevation about 6400'. Any help with its ID is much appreciated.

Phidippus
Thanks for everyone's help in getting this handsome spider identified.

It's an immature Phidippus
in exactly the right light to get that beautiful golden shine from the irridescent stripe!

That shine will fade as it grows, alas.

 
Agree
This is an immature Phidippus.

 
Don, kozz, etc -
can someone please explain why this is an immature Phidippus and not one of the other dendryphantine genera? Not doubting your ID - just trying to learn something... Thanks!

Edit: For example, the current image shows perhaps a darker, fresher spider, but it's hard for me to see a lot of discrete differences from this vouchered image of Pelegrina? Maybe the fused spot on the abdomen in the current image is more well-defined and larger? It would help me greatly to get some tips on these immature dendryphantines, as I can figure out which ones I'd like to try to rear, for example...


 
Dendryphantinae
Ken, in my opinion, there are no other genera outside of Phidippus that have markings similar to the spider in this image. Many species of Phidippus have distinct markings which identify them as Phidippus at 2nd or 3rd instar. Our juvenile Phidippus has a distinct basal band, spots II are large and joined, spots III and IV and small and linear. This is undoubtedly a juvenile Phidippus, and is probably P. audax, which are quite common and colorful in Colorado.

 
Thanks Don!

Could also be -
something like Pelegrina aeneola, which is ubiquitous on foliage in much of the West. Certainly a dendryphantine, at any rate...

Looks like a Phidippus
