Species of fish
Bibarba parvoculus is a cave-dwelling species of loach endemic to a karst cave in Guangxi in southern China.[1][2] Its only known congener (an organism within the same genus) is the surface-dwelling Bibarba bibarba, from which it is believed to have evolutionarily split in the Early Miocene.[3][4]
