An irrational fear of imperfection or incompleteness, or fear of things not reaching their full potential.
From Greek ateles (incomplete, imperfect) and phobos (fear). The combination literally means 'fear of incompleteness,' reflecting anxiety about flawed or unfinished states.
Atelophobia might be the secret fear driving perfectionism—people with this anxiety literally fear anything less than complete perfection, which explains why some perfectionists can never feel satisfied with their work.
