Dorsale stekels (totaal): 2; Dorsale zachte stralen (totaal): 7; Anale stekels 0; Anale zachte stralen: 10 - 13; Wervels: 36. Diagnosis: Notoglanidium akiri differs from other species in the genus in having: an average interorbital distance, 24.1-32.8% of head length vs. smaller in N. boutchangai, N. depierrei, N. pallidum and N. pembetadi, and larger in N. maculatum and N. thomasi; a large eye diameter, 6.6-10.5% of head length vs. smaller in N. maculatum and N. pallidum; a deep adipose fin, 4.7-7.3% of standard length vs. less deep in other species except N. macrostoma and N. walkeri; an average combined premaxillary tooth plate width, 22.0-26.1% of head length vs. broader in N. boutchangai and N. macrostoma and smaller in allother species except N. depierrei and N. pembetadi; only seven soft branched dorsal-fin rays, vs. more than 8 in N. depierrei, N. maculatum, N. pallidum, N. pembetadi, N. thomasi and N. walkeri; and a high dorsal-fin spine length, 9.8-12.8% of standard length vs. shorter in all other species except N. macrostoma (Ref. 94168).
