Up to date TT site?

I know of two sites,

http://arrtripletriad.com/

http://www.ffxivtriad.com/npcs

Neither of them have a 2.55 NPC, Mimidoa, Moraby Drydocks 25 34.

http://ffxivtriad.com/npc/7

afaik they have this npc for a long time. its not new with 2.55. look again mate.

also the second site is pretty much up to date it even has platinum pack data. the other is lacking abit.

I know Mimidoa has been on the latter since day one, let alone since 2.55. I was personally watching that NPC closely for info about how to unlock him as an opponent (main quest).
Wouldn't hurt to inform you about ctrl+F. If you know what you're looking for but just can't see it, type it in to the find box. Should be helpful when the game has more than 33 playable NPCs.
