B. Glyptosterninae Gill, 1872; Glyptothoracini de Pinna, 1996

Glyptothorax ^ZBK, the only genus in this clade, is easily distinguished from other clades of sisorids by having an adhesive apparatus on the thorax with grooves parallel or oblique to the longitudinal axis of the body. Osteological traits used by de Pinna (1996) to diagnose Glyptothoracini include distal portion of premaxilla detached (convergent in Bagariini; data missing for Glyptosternina), and lateral arms of vomer long and thin, extending underneath whole length of articular process of lateral ethmoid.
