Thecadactylus oskrobapreinorum is a species of gecko. It was first described in 2011 from Sint Maarten in the Lesser Antilles. Previous to this it was thought that the only species of turnip-tailed gecko present in the Lesser Antilles was Thecadactylus rapicauda, but the new species is readily distinguishable by its boldly spotted appearance. The specific name honours the two German herpetologists Maciej Oskroba and Stephan Prein who first studied this gecko.
