Tropiocolotes identification

[Jerboa16]

Hello, I used to own two tropiocolotes sp. but I never found out how to identify them... I don’t own them now but I got one photo of one of the individuals, albeit not the best quality. Are there any ways of differentiating the different species?

I purchased them from pet mania in Stockton if that is any help

Welcome to the forum! Have you tried asking the store? Do you have any higher resolution pictures you can post?

Many thanks
I will attempt to ask the store, and hopefully I will get a reply. I will also attempt to ask the place that took them off my hands.
Unfortunately I didn’t take any other photos, which I am rather annoyed at myself with
