An atypid is a member of the Atypidae, a family of creatures most commonly known as the atypical tarantula.

Atypical means not customary or usual. She had an atypical accent for a Bostonian.

The Greek prefix "a-" in "atypical" means "not" or "without," so "atypical" means not typical or not conforming to the usual pattern.
