This is just a beautiful species of jumper,
Habronattus icenoglei ♂, who posed nicely for me to get some natural light images.

These images were taken with a Nikon D810, using the all-manual 20mm f/2.8 Ai-S lens,
reversed, on a RRS tripod + macro rail & remote switch. Natural light @ f/16, 2-second shutter, no flash.

PS:
Here is the encounter: I actually spotted it on a dead tortoise shell while in Joshua Tree, CA and only had my 300mm. I collected it and took these studio shots when I got home
