Diagnosis: Notoglanidium walkeri differs from other species in the genus in having: an average interorbital distance, 27.8-33.3% of head length vs. smaller in N. boutchangai, N. depierrei, N. pallidum and N. pembetadi, and larger in N. maculatum and N. thomasi; a relatively small combined premaxillary tooth plate width, 13.7-16.1% of head length vs. larger in N. akiri, N. boutchangai, N. macrostoma and N. pembetadi; and a relatively large number of soft dorsal-fin rays, 11-15 vs. less in N. akiri, N. boutchangai, N. depierrei and N. macrostoma, and more in N. maculatum (Ref. 94168).
Body shape (shape guide): elongated.
