Gogangra Roberts, 2001   ZBK : 83. (Type species: Pimelodus viridescens Hamilton, 1822   ZBK , by being a replacement name. Replacement name for Gangra Roberts & Ferraris, 1998   ZBK ; preoccupied by Gangra Walker, 1862   ZBK , in Lepidoptera). Gender masculine.

Gangra Roberts and Ferraris, 1998   ZBK : 333. (Type species: Pimelodus viridescens Hamilton, 1822   ZBK , by original designation. Preoccupied by Gangra Walker, 1862   ZBK ; in Lepidoptera, replaced by Gogangra Roberts, 2001   ZBK ). Gender masculine.

Diagnosis (based, in part, on Roberts & Ferraris 1998): Small conical teeth in lower jaw; branchiostegal membranes free from isthmus; small serrations on anterior margin of pectoral spine; no well-developed maxillary barbel membrane; outer and inner mental barbels widely separated, origin of inner barbels anterior to origin of outer barbels; short nasal and maxillary barbels; palatal teeth absent.

Gogangra   ZBK is distinguished from Gagata   ZBK by having the outer and inner mental barbels widely separated, with the origin of the inner barbels anterior to the origin of the outer barbels (vs. barbels close together with their origins nearly parallel) and by having the branchiostegal membranes free from the isthmus (vs. broadly fused to the isthmus). Gogangra   ZBK is distinguished from Nangra   ZBK by having maxillary barbels extending only to the pectoral-fin base (vs. extending to the pelvic-fin base), by having nasal barbels shorter than the eye diameter (vs. longer than the eye diameter, reaching at least to the eye), by having small serrations on the anterior margin of the pectoral spine (vs. no serrations), and by the absence of palatal teeth and a well-developed maxillary barbel membrane. Gogangra   ZBK is distinguished from Bagarius   ZBK by having only small conical teeth in the lower jaw (vs. teeth in lower jaw markedly heterodont), by having small serrations on the anterior margin of the pectoral spine (vs. no serrations), and by the lack of a welldeveloped maxillary barbel membrane. Gogangra   ZBK is distinguished from Sisor   ZBK by having small (vs. large) serrations on the anterior margin of its pectoral-fin spine, no bony plates on the dorsum, no spine in the adipose fin, the origin of the inner mental barbels anterior (vs. posterior) to the origin of the outer mental barbels), branchiostegal membranes free from the isthmus (vs. broadly fused to isthmus), the uppermost caudal-fin ray not greatly elongated (vs. greatly elongated, more than half the length of the body), and no welldeveloped maxillary barbel membrane.

Description: Dorsal fin with 1 spine, 6 branched rays; pectoral fin with 1 spine, 8-9 branched rays; 6 pelvic-fin rays; 7-9 branched anal-fin rays. Head moderately depressed, jaws with several rows of small conical teeth. Palatal teeth absent. Maxillary barbel not extending posteriorly beyond head; barbel membrane absent or greatly reduced; base of barbel stiff. Coracoid process visible externally. Live specimens with viridescent or silvery supraopercular mark. Pectoral-fin spine smooth anteriorly, serrate posteriorly. Dorsal spine smooth anteriorly and posteriorly. No thoracic adhesive apparatus. Paired fins non-plaited.

Distribution: Ganges, Meghna and Brahmaputra drainages, India and Bangladesh (Jayaram, 1999; Ng, 2005f).
