ABSTRACT

Glyptothorax irroratus, a new species of sisorid catfish from the Mekong River drainage in Laos and China, is described. It differs from its Indochinese congeners in having both large and small tubercles arranged irregularly on the lateral surfaces of the body and by combinations of colour pattern, morphometry (with particular regards to the eye, body depth, adipose fin and caudal peduncle) and thoracic adhesive apparatus morphology.
