Etymology The generic name comes from the Greek glyptos, meaning carved, and thorax, meaning breastplate (or the part of the body covered by it), in reference to the folds of skin comprising the thoracic adhesive apparatus. The specific name comes from the diminutive form of the Latin noun radius, meaning a ray or rod, in allusion to narrow, elongate appearance of this species.

Identification Sisorid catfishes of the genus Glyptothorax Blyth are benthic inhabitants of torrential waters of rivers and streams in montane and submontane parts of tropical Asia. The members of the genus are adapted to attach themselves to rocks and boulders against strong currents by means of a thoracic adhesive apparatus comprising grooves and folded pleats of skin parallel or oblique to the longitudinal axis of the body. The genus has a wide distribution, ranging from Turkey and Syria in the west, to India and China in the east, and extending further southeastward to Indonesia. With 84 nominal species, Glyptothorax are the most speciose genus of catfishes in Asia (Eschmeyer et al., 1998, Ng, 2005); 67 species were treated as valid by Thomson & Page (2006).

Glyptothorax radiolus can be identified by the presence of a prominently plicate ventral surface of the pectoral-fin spine and the first pelvic-fin ray,a wedge-shaped central depression in throracic adhesive apparatus devoid of skin ridges, unculiferous ridges of thoracic adhesive apparatus not extending anteriorly onto gular region, absence of distinct pale midlateral stripe on body and 36 total vertebrae.
