It still is a plated lizard AND a Zonosaur .
Its just not from the genus Gerrhosaurus like so many (not all) of the african plateds but from the malagasy genus Zonosaurus.
Zonosaurus quadrilineatus, the four lined plated/Zonosaur are sand swimmers and dwellers. But the genus Zonosaurus also contains lizards with habtis which are very uncommon for plateds. Some Zonosaurus do even live a semiaquatic life almost like alligators.
So you have to do your homework if you aquire a Zonosaur.

Hope that helps
