Rameshori, Y & W Vishwanath, 2012. A new catfish of the genus Glyptothorax from the Kaladan basin, Northeast India (Teleostei: Sisoridae). Zootaxa 3538: 79–87.
Abstract
Glyptothorax churamanii, a new sisorid catfish species from the Kaladan basin of Mizoram State, Northeast India is described. It is distinguished from the congeners of Glyptothorax in the NE Indian region by the combination of the following characters: an oblong thoracic adhesive apparatus opening caudally with an inverted V-shaped median depression on its posterior half; the ventral lobe of the caudal fin longer than the dorsal lobe, with diffused black submarginal bands on each lobe; sparsely tuberculate skin; ventral surfaces of pectoral spine and first (and sometimes second) rays of pelvic fins pleated, plicae on pectoral spine arranged in rows, continuous distally and dissociated in a series of three to five hexagonal-shaped spots in each row; and 3+10 rakers on the first branchial arch.
