Diplodactylinae, and Gekkoninae subfamily - differences?

[Jheuloh]

What exactly separates "diplodactylinae" geckos from the "gekkoninae" subfamily? I've tried examining popular examples of diplodactylinae & gekkoninae both, but other than noting differences in pupil design & claw development, I can't find any visible differences between the 2 subfamilies. Are there internal anatomy differences between the 2 subfamilies? Or is there a visible difference between them that I'm ignoring/not observing?

Edit: To elaborate on what I say about "Noting differences in pupil design & claw development" - to me, when the pupils have constricted, it looks as if diplodactylinae has "cat" shape pupils rather than the "pinhole" pupils that gekkoninae subfamily members all seem to have, and diplodactylinae also seem to have prominent, well developed claws compared to gekkoninae.

I remember reading an article that goes into complete detail of how and why they are sorted the way they are, but for the life of me, I can't find it right now. However, I did find this one, which might get you started with some of the info you're looking for: AMNH Scientific Publications Library: Item 2246/1985
It's a pdf which you can download. The webpage is just a short summary.

From what the non PDF article implies, diplodactylinae could be best described as a "somewhat primitive" wall-climbing gecko, with gekkoninae being the current "advanced" descendant of the common ancestor of all geckos. Eublepharis seem to be nearly unchanged descendants of the Ardeosauridae. Does that sound right?

The PDF'll be giving me some reading to do!
