Gasteracantha elipsoides is somewhat close to your description, but I'm not sure if it is the same. Gasteracantha elipsoides usually has six spikes, usually reddish.
If the main part of it is brown or tan, then it is a male black widow, or a juvinile female.
The name of the spider is Phidippus Audux. It is a jumping spider.
Well, what size is the spider.
If it is rather large and hairy, then it could be the Mexican Red-Kneed Tarantula.
Banana Spider, I'm guessing. Google the Banana Spider to make sure it's the one you saw. Hope that helps.
If the red color is in the shape of an hourglass it is a black widow.
White tailed spider very dangerous and toxic
A sack spider?
A spider that has a dark brown abdomen, with reddish brown legs, and a light beige bottom with dark brown club like claws could be a wolf spider. It could also be a tree spider.
It depends on what species you desire, and what you consider huge. In my opinion the male Hobo Spider has a pretty large abdomen. However when comparing most male spider's abdomen to the female abdomen, the answer might as well be no.
The cross spider has white crosses on his abdomen. Another North American spider with white on his belly is a parson spider who has a white stripe down his abdomen.
abdomen... i think
=on their ABDOMEN!!=
abdomen
no they have an abdomen, and a cephalothorax.
In a spider, the Pedicel separates the cephalothorax from the abdomen.
A big white spider with brown, reddish legs might be a crab spider. Crab spiders like to live in outdoor areas where there is plenty of food for them, like in a garden.
