Hemibagrus punctatus,[3] or Nilgiri mystus, is a species of fish in the family Bagridae. It was first described by Jerdon in 1849.[4][5] It is endemic to east-flowing rivers in the Western Ghats of India. Of these, the species is likely only found in the Kaveri River; records from the Krishna River may actually be of H. maydelli. However, one record from the west-flowing Bharatappuzha River has been tentatively assigned to this species.[6] The last record of this species was in 1998, and it may have experienced a population decline of nearly 100%; thus, IUCN categorizes the species as critically endangered (possibly extinct). It is threatened by habitat degradation by excess siltation, excess fishing, and dam construction.[1] However, based on several specimens caught by fishermen between 2011-2012 that likely belong to this species, as well as testimonies from local fishers, moderate populations of this species may still be extant in the region.[6]
