Sasanidus
Sasanidus and Eidinemacheilus are two loach genera endemic to the Persian Gulf basin. Only one species of Sasanidus is known, and no superficially similar species have been reported from Pakistan or India. Sasanidus is distantly related to Paraschistura, and it cannot be excluded that other species of Sasanidus might exist on the Indian subcontinent, where a large diversity of nemacheilid loaches exist, usually identified as Paraschistura or Schistura . Furthermore, an understanding of the phylogeny of loaches is virtually lacking in this region.
