Can anyone identify this jumper???

Hi! My friend caught a jumping spider last night and offered it to me although I’m having a hard time figuring out what species it is! Does anyone know?

Looks similar to my female tan jumper I caught yesterday. Has similar coloration and the white palps like mine. I live in western NC, though. Not sure what part of the U.S. you live in.

What is the location it was found? It is within genus Habronattus. If you are in west USA than maybe Habronattus hirsutus

I live in Nevada and the jumpers that are usually found here are bold jumpers

Platycryptus californicus are found in Nevada as well. That little guy looks a bit like some of the pictures I pulled up.

To clarify, this is 100% not within genus Platycryptus. This is within the genus Habronattus, common name for the genus is “Paradise jumpers”.

Seeing as it was found in Nevada, it could very well be Habronattus hirsutus.

I'm honestly curious how you can tell. None of the Habronattus hirsutus I see online look to match the pictures. What part makes you 100% certain it's not a Platycryptus californicus? I'm still new to identifying the different genuses and honestly want to learn how to spot the differences

I will give a detailed explanation a little later when I’m free!

Platycryptus is a genus with four described species, and one (or possibly more) undescribed species. Platycryptus undatus, Platycryptus californicus, Platycryptus magnus, Platycryptus arizonensis, and the undescribed Platycryptus sp.

The range of Platycryptus undatus is eastern North America (Canada, USA, Mexico)
Platycryptus californicus in western North America (Canada, USA, Mexico)
Platycryptus arizonensis is in Arizona and immediate neighboring states (California, Nevada, etc.)
Platycryptus magnus is in Mexico, Central America, and South America.
And the range of the undescribed species isn’t fully known, but the only individuals of the species were found in west Texas.

That leaves two species of Platycryptus in the range, Platycryptus californicus, and Platycryptus arizonensis.
P. californicus has dark areas on the sides of the cephalothorax. So it rules out that species. And P. arizonensis has an orange-brown color usually. So it rules out that species. In addition, Platycryptushas an elongated, vertically flattened body, with an undulating pattern along the entire abdomen.
The one in this post does not.
So it can’t be Platycryptus.

This one has a shorter, seemingly vertically elevated body, and elongated third legs. The main genera with these features in America are Naphrys and Habronattus. (There are of course others too)
Naphrys is not in western USA.
Habronattus females have this shape and color often.
The color of the body and legs in combination with the little almost fishbone pattern on the abdomen, and the little pattern near the eyes that Im not sure how to describe, black and white alternating stripe? These things are present in Habronattus hirsutus.
However, keep in mind I have been learning how to identify the species within Habronattus for only about a month. I can identify some species with high accuracy, but it is an incredibly diverse and large genus, so I have much to learn. So take my ID of Habronattus hirsutus with a grain of salt. However, judging by the overall matching patterns, and the range, and that it’s a common species, I think there is a good chance for it to be Habronattus hirsutus.

I did a quick google search of the species H. hirsutus. I think the individuals online you saw were all males or a separate species entirely.
Many jumpers, including genus Habronattus are sexually dimorphic, meaning both genders look different. I use Bugguide, iNaturalist (with a grain of salt), and scientific papers as reference when identifying. As well as personal experience.
