From the photo, if that really is a Scheffler's, the light/yellowish markings on kimhowelli stop around the neck, and this animal's coloring extends far down the back. Unless kimhowelli has more variable markings than I realized, I don't think that is kimhowelli.
There are photos of picturatus here:
Geckoes
They also look a bit like kimhowelli, it seems many lygos have similar patterning.
The author's assumption that the baby gecko is of the same species because it was in the same area probably led to the confusion with the hatchling--different species of Lygos do share the same areas and environments (mombasicus and kimhowelli, for example). So, the baby probably isn't Scheffler's.
It really is tough to find photos of a lot of animals online. I'm personally planning to photograph all of mine when I get more lygos. (I'm expecting kimhowelli, angularis, and possible conradti from Switzer reptiles as soon as the weather breaks a bit). I like to take some of my best photos, and put them up on wikimedia commons, and let everyone use them. I just put up the decent photo I managed to get of my female williamsi, since there was only one photo of a male up there.
