, a new species, is described from the Barak-Meghna-Surma River drainage in Manipur, north-east India. It is distinguished from its congeners except, G. scrobiculus in having a furrow running along the entire length of the ventral surface of the pectoral spine. However, the new species differs from G. scrobiculus in having a posteriorly serrated (vs. smooth) dorsal spine, longer caudal peduncle, shorter head length, shorter adipose-fin base, more abdominal vertebrae (22-23 vs. 19-20) and presence (vs. absence) of numerous tubercles on the pectoral and pelvic-fin rays.
