Abstract
This study describes two new species of Pseudolaguvia, a genus of miniature sisorid catfishes, from the Brahmaputra and Ganges river drainages in northeast India. The two new species (Pseudolaguvia ferruginea and P. flavida) are diagnosed from congeners by a combination of dorsal spine morphology, length of the thoracic adhesive apparatus, and relative measurements of the dorsal-fin base length, length of fin spines, adipose-fin base length, dorsal-to-adipose distance, caudal peduncle length and depth, body depth, head width, and snout length.
