Special Remarks: It was collected from a fast flowing stream at Namsing, Anchal Ghat and Portung forest. However it was collected from a slow moving stream at Sigar village, also. This species can be easily identified by the presence of a strong dorsal spine serrated at its inner edge. Its status is vulnerable ( Menon, 1999) but in Arunachal Pradesh it is abundantly found.
