Key to the genera in Auchenoglanidinae

1 Skull roof bones clearly visible through the skin; supraoccipital process massive, long and broad, touching the very well developed, broad nuchal plates; premaxillary tooth plate composed of two plates (each longer than broad) with a combined width of 3.9–10.2% HL; caudal fin weakly forked...................................................... Auchenoglanis

- Posterior cranial bones barely or not visible through the skin; supraoccipital process longer than wide or greatly reduced, and may or may not touch nuchal plates (usually narrow and not visible externally); premaxillary tooth plate composed of two plates (each at least as broad as long) with a combined width of 6.9–41.7% HL; caudal fin rounded or straight.......... 2

2 Eyes without free border, positioned dorsally on head, and reduced or not (3.3–13.3% HL) (Fig. 11)....... Notoglanidium

- Eyes with free border, positioned dorsolaterally on head, and not reduced (9.0–17.2% HL) (Fig. 11)..... Parauchenoglanis
