a brown reclouse
The distinguishing features that can help identify a small brown spider with a large abdomen are its size, color, and the prominent size of its abdomen compared to its body.
A spider with a large brown abdomen and long black shiny legs could possibly be a brown widow spider (Latrodectus geometricus). Brown widows are known for their distinctive appearance, with a bulbous brown abdomen and long, slender black legs. If you come across a spider fitting this description, it is advisable to exercise caution as some spider species can be venomous.

It sounds like you are describing a Woodlouse Spider (Dysdera crocata). These spiders are brown with a distinctive large yellow or orange abdomen, and they are known for their behavior of rolling into a ball when threatened for protection.
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.
A spider with a large white abdomen may indicate that it belongs to a specific species or genus within the field of arachnology. The color and size of the abdomen can help researchers identify and classify different types of spiders.
A spider with a large abdomen plays a significant role in the ecosystem by indicating its ability to store more food and survive longer without eating. This allows the spider to better withstand periods of scarcity and reproduce successfully. The large abdomen also affects the spider's behavior, as it may move more slowly and be less agile in hunting, but it can also attract mates and deter predators with its size.
It is likely a brown widow spider. They're not as venomous as a black widow spider, but you should still be very careful with it.

In Kentucky, common spiders include the black widow, brown recluse, and wolf spider. Black widows are shiny black with a red hourglass shape on their abdomen. Brown recluses are light brown with a violin-shaped mark on their back. Wolf spiders are large and hairy with distinct eye patterns. It's important to be cautious around these spiders as some can be venomous.
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.
No, they are NOT naturally found in Oregon. However, the hobo spider does occur in Oregon and the Northwest states. It is commonly mistaken for brown recluse, and can cause the same effects (skin lesions).http://brownreclusespider.com/faq.htm http://www.oregon.gov/ODA/PLANT/IPPM/spider.shtml
