In order of my own preference (although they are all pronounced almost exactly the same way): Sophymoth, Sophimoth, Sophemoth, Sophamoth, Sophomoth, Sophumoth
"sophos" (Greek for wise) + <connecting vowel for smoothness> + "moth"
The Psychic typing and general angelic quality makes me think that it is a wise and enlightened creature. Also, "Soph_moth" flows well, and imo it sounds like a name GF would come up with.
