The False Black Widow, Steatoda albomaculata, is in the same family, Theridiidae, as the famous Black Widow, Latrodectus sp. It is native to Europe, not North America, but has become common on the whole Pacific Coast. They sometimes occur in houses. They have mild venom and a bite can cause symptoms similar to a mild black widow bite.
