Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); kerioensis: The specific epithet refers to the Kerio River, Lake Turkana basin, where the species is believed to be endemic (Ref. 105400).

Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 2; Rückenflossenweichstrahlen (insgesamt): 6; Afterflossenstacheln 0; Afterflossenweichstrahlen: 11. Diagnosis: Chiloglanis kerioensis is distinguished from C. somereni and C. devosi in having fewer mandibular teeth, eight or fewer vs. eight or more; and a larger orbit, more than 4% of standard length vs. less than 4% (Ref. 105400). It is distinguished from C. brevibarbis by longer barbels, maxillary barbels usually more than 30% of head length vs. less than 30%, medial mandibular barbels more than 10% of head length vs. less than 9%, and lateral mandibular barbels more than 17% of head length vs. less than 15%; and in the arrangement of the mandibular teeth, exposed length of teeth not equal to row width vs. exposed portion equal or greater than row width in C. brevibarbus populations (Ref. 105400). It differs from C. deckenii in having a longer premaxillary tooth pad, more than 3% of standard length vs. less than 3%; and longer lower lip, more than 60% of head length vs. less than 55%; the species is distinguished from Chiloglanis sp. aff. deckenii by the following combination of characters: C. kerioensis has a longer postcleithral process, more than 9% of standard length vs. less than 9%, and longer lateral mandibular barbels, more than 15% of head length vs. less than 15% (Ref. 105400).
Found in the medium rapids and aggregated near the larger boulders (Ref. 105400).
