A new species of the genus Glyptothorax, Glyptothorax obliquimaculatus sp. nov. is described from the Xiaohei River, a tributary of the Nanting River, Salween drainage, in southwestern Yunnan province, China. This new species can be distinguished from its congeners by the following combination of characteristics: unculiferous ridges of the thoracic adhesive apparatus extending anteriorly onto the gular region; body with irregular dark blotches scattered along lateral surface (blotches mostly oblique); skin smooth on head and body; dorsal spine smooth without serrations on its posterior margin; lips smooth; posterior margin of pectoral spine with 7–8 serrations; dorsal-fin base 11.0–13.2% SL; pectoral-fin length 15.6–19.6% SL; depth of caudal peduncle 8.6–9.8% SL; head width 19.1–24.0% SL; nasal barbel length 23.3–33.3% HL.
