Scaphognathops

Scaphognathops is a genus of cyprinid fishes found in Southeast Asia. Thai vernacular names are pla pak pian (ปลาปากเปี่ยน), pla pian (ปลาเปี่ยน) or pla ta dam (ปลาตาดำ). It is restricted to Mekong Basin, and not easy to find.

This genus was named by H. M. Smith, an American ichthyologist who lived and worked in Siam (now Thailand). He first intended to name the group Scaphognatus, but this name was already used for a group of prehistoric winged reptiles.
