Riti - West African violin-like instrument, but played upright like an Erhu. Really scratchy and scrapey.
Rebec - viol used in Medieval/Renaissance music. 3 strings I think - reminds one of a more fluid hurdy gurdy.
Regal - another Medieval instrument. A Brass reed portative organ that sounds similar to a Crumhorn.
Gombri - Middle Eastern bass lute.
That's it. Next time I'll be more specific.
