Looking for a wrasse ID

[ACBlinky]

I bought my fairy wrasse from an un-labeled tank. The employee wasn't sure what species she was, but I wasn't concerned - I figured I'd be able to ID her from pictures in my marine atlas or online... turns out it's not that easy!
I've seen pictures of Cirrhilabrus flavidorsalis that resemble my fish, though she doesn't have a black spot near her tail, and some of C. lubbocki that look just like her... but other pics of Lubbock's look nothing like my fish. I'm hoping someone here will take one look at her (or... him? I'm assuming she's female since she's alone in the tank and AFAIK these fish are female by default) and know what species she is. Thanks for the help!

Here she is, sorry for the lousy pics, she's FAST and hard to catch on film.
