I am interested in these little guys aswell and have found that L. luteopicturus is often confused with L. picturus. I haven't managed to find out exactly which is which. But care is apparently the same.
All species of Lygodactylus are diurnal (active in daytime), just like day geckos. And set up can be much like them. They need a tall vivarium, and loads of vertical branches and plants. They need alot of UV, more so then days, as well as a spot light to provide a hot spot around 35 C. The rest of the tank should be slightly cooler. A water dish is needed even though i doubt they'll drink from it. Misting the tank everyday will help keep the humidity high, above 50%.
Have a look on the web page below. It gives more info.
