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.
 
KEYWORDS: Sisoroidea, Sisorinae, Bagariini, Mekong River


Glyptothorax irroratus sp. nov.

Etymology: The Latin adjective irroratus (-us, -a, -um) means covered with dew; in zoology used to mean besprinkled with drops or particles. This is used in allusion to the irregular tuberculation on the sides of the body and caudal peduncle.
