Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); mongoensis: The specific epithet refers to the Rio Mongo, a tributary to the Rio Wele in Equatorial Guinea, where the species is presumed endemic (Ref. 120898).

Dorsale stekels (totaal): 2; Dorsale zachte stralen (totaal): 4-5; Anale stekels 0; Anale zachte stralen: 7 - 8. Diagnosis: Chiloglanis mongoensis is readily distinguished from all other valid species of Chiloglanis with the exception of C. marlieri and C. harbinger in possessing 28-30 mandibular teeth in one row (Ref. 120898). Chiloglanis mongoensis is distinguished from C. marlieri in possessing a longer dorsal spine, 1.8 times into head length versus 3.1 in C. marlieri (Ref. 12898). It is distinguished from C. harbinger in having fewer premaxillary teeth, 99-116 versus 150-224, arranged in fewer rows, 4-5 versus 7; a longer dorsal spine, 9.0-9.7% of standard length versus 7.8-9.0%; a deeper body at anus, 14.0-16.0% of standard length versus 11.7-13.8%; a larger eye, 3.7-4.6% of standard length versus 2.9-3.5%; and a higher adipose fin, 2.6-3.9% of standard length versus 1.6-2.3% (Ref. 120898).
Found where the Rio Mongo was shallow, substrate mostly sand and gravel, and there was little flow (Ref. 120898).
