Is there a herpetologist in the house?

My kum Miroslav (see previous posts just below) has taken a picture of this lizard, which is quite common in Nigeria. This is a male (females are more drab and single-colored) and it is about 0.5 meters long (20 inches). What is the common name and the Latin name of this lizard? Please tell me in the comments:
