Relevant Information:

Exostoma is distinguished from Glyptosternon, Glaridoglanis, Pareuchiloglanis, Euchiloglanis and Parachiloglanis by having a continuous post-labial groove. Exostoma is distinguished from Pseudexostoma and Oreoglanis by having homodont (vs. heterodont) dentition in the lower jaw. It is further distinguished from Oreoglanis by having oar-shaped, distally flattened (vs. pointed) teeth in the upper jaw, and from Pseudexostoma by having homodont (vs. heterodont) teeth in the upper jaw. Exostoma is distinguished from Myersglanis by having tooth patches separated in the upper jaw and oar-shaped, distally flattened teeth in both jaws (vs. tooth patches juxtaposed and pointed teeth in both jaws). Exostoma is further distinguished from Pseudexostoma and Oreoglanis by having 10–11 branched pectoral rays (vs. 16–18).
