I was looking for this last night as well. There is an extremely small camp of Ixial in Alder Springs. It kind of looks like a little circle near a cliff with some structure in the middle. There are only 8 mobs that spawn in that area, so just keep looking and you will see them.
It's worth noting that not all places named in the map are actually "main" areas in the map, however when you open it, the top left corner has the name of the area you are in, as long as that name matched with the tool tip in your hunting long the enemy could be located in that position.
That is the case for Aldersprings which spawns a few more sectors to the east.

I've used the XIVDB.com database myself to handle most of my questions regarding hunting logs. It may not be 100% complete, but has usually sufficed what I needed it for.
I know this is off topic alittle, but dam that was a fun fight, when in as level 25 Gladiator, had to fight my way in and clear a few more mobs then pulled lightwing to the side and we duked it out for a few mins, came out on top, just had a blast hunting that guy.
