Identification
Its full user-agent string, exactly as it arrives at the gate:
There is no operator to verify against. This name is what software calls itself when nobody gave it one.
No operator stands behind this name, so there is nothing to check its visits against.
How to block UnGovrBot
Add these two lines to the robots.txt file at the root of your site. Well-behaved crawlers read it before they crawl, so the change applies from UnGovrBot's next visit. Nothing else on your site needs to change.
# Block UnGovrBot from the whole site User-agent: UnGovrBot Disallow: /
Or let it visit but keep it away from part of the site:
# Let it in, but keep it out of one room User-agent: UnGovrBot Allow: / Disallow: /members/

Where it comes from

Networks and countries come from the visitor's IP address, looked up in a local copy of the DB-IP database. The addresses themselves are never stored.
