Abstract We describe Glyptothorax intonsus , a new species of sisorid catfish from the Nam Mang watershed in the Mekong River drainage of Laos. The new species is distinguished from all Mekong drainage Glyptothorax by a combination of its very long nasal barbels, head and body proportions, features of the thoracic adhesive apparatus and lateral line, colouration and body tuberculation.
Ng et al. (Wed,) studied this question.
