Diagnosis: No post-labial groove, lower lip continuous with isthmus without demarcation; gill openings not extending onto venter; homodont dentition; pointed teeth in both jaws; tooth patches joined into a crescent-shaped band in upper jaw; 13-16 branched pectoral rays.
Parachiloglanis ZBK is distinguished from all other genera of Glyptosternina by having no post-labial groove; the lower lip is continuous with the isthmus without demarcation (vs. having either a continuous or medially interrupted post-labial groove). It is further distinguished from Oreoglanis ZBK and Pseudexostoma ZBK by having homodont (vs. heterodont) dentition in the lower jaw, and from Pseudexostoma ZBK by having homodont (vs. heterodont) dentition in the upper jaw, and from Glyptosternon ZBK by not having the gill openings extending onto the venter.
Description: 7 dorsal rays; 13-16 branched pectoral-fin rays; 6 pelvic-fin rays; 5-7 anal-fin rays. Head depressed; body elongate, depressed anteriorly.
