Insect and Spider Identification: Jumping spider identification?, 3 by kaidamoon

Hello! I\'m Kay, a spider enthusiast from the suburbs of Buenos Aires, Argentina. I recently found these spiders roaming around my house- and I found them quite alluring! After some research I\'m pretty sure they are jumping spiders, but I\'m not sure of what else. I caught one, it was incredibly smart and cute, but I let it go after taking some pictures. I have also watched it ambush and catch ants around its size! It was very skilled :)
I\'ll send some pictures- if they aren\'t clear, it is a very small spider, on a brick for size comparison. It has two horizontal black stripes on its back and a very strange round yellow marking on its head. It almost looks like an upside-down omega symbol!
Its overall color is a very dull brown, it has several stripes on its legs.
I wish I could have taken better pictures, but it seems like it\'s going to permanently reside in my garden wall- it made itself a little home on a hole, and I get the feeling there might be some more around the place!
I hope someone can help me identify these little ones as I couldn\'t find anything about them online, and I don\'t have the time to do a detailed search.
Thank you! :)
