Abstract
Glyptothorax exodon, a new species of rheophilic catfish from Borneo is described here. It can be distinguished from Sundaic congeners except G. platypogonides and G. siamensis in having a slender body (13.8â??15.8% SL vs. 17.3â??20.9). It differs from G. platypogonides in having a deeper caudal peduncle (6.8â??7.3% SL vs. 5.7â??6.7) and more exposed premaxillary teeth when the mouth is closed and from G. siamensis in having a larger eye (10.4â??13.2% HL vs. 7.5â??9.1) and a mottled color pattern lacking distinct pale stripes (vs. a uniform dark brown with distinct pale midlateral and mid-dorsal stripes).
