Could that be an immature black widow male?
Porbably one of the tunnelweb spiders the banded tunnelweb spider and the black tunnelweb spider both have a body legnth of 25mm.
The only spider I have seen like this was a common sight in Kimberley South Africa. We called it a button spider because its back look like a button. It was not a black widow and it was not orange and did not have the hourglass marking that is common with the black or brown widow - also called the button spider.
The distinctive appearance of a brown spider with black and white stripes includes a brown body with alternating black and white stripes on its legs.
could be a spider wasp
There is an estimated 43,678 species of spiders in the world. It is best to avoid any spider or insect that can not be identified. One way to identify a spider could be to go to the library to research spiders comparing images in a book.
This spider more than likely is an Argiope, this is a common spider than can be found all over the world. If you seen the web, this spider is known to spin a white zigzag pattern on their web.
The spider with a big white body is likely a white orb-weaver spider.

a black spider
The spider with two black stripes on its body is commonly known as the zebra spider.
I suggest it's a Zebra spider; a species of jumping spider. See the link I've attached below in the related links section.
