Diagnosed from its congeners by having diminutive eyes, posterior naris absent, presence of a triangular skin flap at mouth corner, dorsal and ventral fin fold deep and extending forward on the head to a vertical through tip of pectoral fin. Differs from Pygidianops magoi by the presence of six laterosensory pores on head, presence of pectoral and anal fins, presence of 12-13 caudal fin rays associated with the caudal plate.
