Looks like you feel quite strongly about this talasiga.
Perhaps you should sign up to Wikipedia & correct their pages on Santoors & Santurs:
The santur is a Persian hammered dulcimer similar to the Indian santoor.
The santoor is a trapezoid-shaped hammered dulcimer often made of walnut, with seventy strings.
The special-shaped mallets (mezrab) are lightweight and are held between the index and middle fingers.
A typical santoor has two sets of bridges, providing a range of three octaves.
The santoor is a hammered dulcimer, derived from the Persian santur (which is believed to be the first instrument of its type), and related to similar instruments in Iraq, Pakistan, India, Armenia, Turkey, and other parts of Asia.
It is related to the shata-tantri veena of earlier times.
The Kashmiri santoor is more rectangular and can have more strings than the original Persian counterpart, which generally has 72 strings.
Wikipedia - Santoor
Many instruments around the world at least in part derive from the santur.
Similar forms of the santur have been present in neighboring cultures like Armenia and Turkey for centuries.
The Indian santoor is thicker, more rectangular, and can have more strings.
Its corresponding mallets are also held differently.

Looks like Wikipedia have it all wrong!
With info like that on such a reputable site, it's no wonder folks like me get confused, is it.
So the quicker someone changes it, the sooner newcomers to the instruments, like me, will better understand them.
