If you look at the various Star Trek minis on the Lost Minis Wiki, they don't match up with any Citadel or FASA minis. And I could not find any pictures of the 25mm Wee Warriors line, so I don't have any reference there. Take a look and let me know what you think.
UPDATE (2/25/16): I went back and took another look at each miniature, and what I discovered was that there are 12 different poses total. 6 human poses, and 6 alien poses. This would be consistent with the Wee Warriors entry on the LMW, which lists 2 sets of 6 miniatures each - Landing Party and Alien Set. So it appears I have 2 sets of Landing Party, and 1 set of Aliens, with an extra female Romulan for a total of 19 minis. Of course, I still don't have have any photographic evidence to back me up, so it's still just a theory at this point, although a better than average one in my opinion.
