Akysid catfishes of the genus Acrochordonichthys Bleeker ZBK, 1858, inhabit the bottom of rivers throughout Southeast Asia.

They have a highly rugose skin with tubercles arranged in longitudinal rows along the side of the body, a long, low adipose fin, and an emarginate caudal fin.

Until the recent revision by Ng & Ng (2001), the genus has been poorly studied, mainly due to difficulty in distinguishing the species and lack of sufficient comparative material.
