Abstract
We describe eight new species of the sisorid catfish genus Oreoglanis from the Chao Phraya, Mekong and Salween river drainages in northern and western Thailand. The new species are diagnosed by a combination of morphology of maxillary-barbel tip, lower-lip morphology, extent of pectoral fin, fusion of the adipose fin with the upper procurrent caudal-fin rays, caudal-fin morphology, and the relative proportions of the head, snout, nasal barbel, interorbital distance, eye, body depth at anus, adipose fin, caudal peduncle and post-adipose distance. The taxonomy of O. pumatensis, a poorly known species from Vietnam is also discussed; it is considered a junior subjective synonym of O. infulatus here.
