A boy comes in with a bite while putting on a shirt, and the spider above is the culprit. He didn't think much of it at the time since it wasn't initially painful. But over the next few hours, he started having more and more pain. He also has malaise, nausea, fever, and myalgias.
Initially, the parents describe erythema with two cutaneous puncture wounds on the skin. Over time, it developed a central pallor, and now on exam 2 days later, you note a dark, depressed eschar. It looks almost necrotic, and the area has decreased sensation.
Challenge: Identify the spider.

He can "pop" his ears and then they sound normal for a while. On exam, you see that the tympanic membrane is retracted without moving properly.
