What is the name of this string instrument from Madagascar?

The kabosy is a box-shaped wooden guitar commonly played in music of Madagascar. It has four to six strings and is commonly thought to be a direct descendant of the Arabic oud. The kabosy has staggered frets, many of which do not even cross the entire fretboard, and is generally tuned to an open chord. A kabosy-like instrument with standard frets is known as a mandalina or mandoliny. Notable players of the kabosy include Babata and Jean Emilien.
