Etymology: Parauchenoglanis: Greek, para = near + Greek, auchen = neck + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical; 15°N - 13°S
Africa: from the Ouémé River in Benin to the rivers Sanaga (Ref. 50834, 78218, 81642) and Dja (middle Congo River basin) (Ref. 51193) in Cameroon. Also present in the middle Congo River basin in Democratic Republic of the Congo (Ref. 41580, 41585, 41590, 41591, 46861).

Morphology | Morphometrics
soft rays: 7 - 8. Diagnosis: caudal peduncle short and broad, its depth more than 2 times the horizontal distance between anal and adipose fin bases, rarely even deeper; anterior edge of pectoral spine coarsely serrated, with numerous small serrations, more numerous than those along the posterior edge (Ref. 81642). Barbels generally short: maxillary barbel reaching a little beyond pectoral spine base, external mandibular barbel not reaching tip of spine (Ref. 81642) but up to level of dorsal-fin spine, and inner mandibular barbel up to beginning of opercula (Ref. 57126), but it should however be noted that some juvenile specimens have slightly longer barbels (Ref. 81642). Adipose fin not always high and solid; colour pattern usually with 5-7 vertical bands (Ref. 81642).
Nocturnal and crepuscular; preys on insect larvae, crustaceans, and small fishes (Ref. 6868). Maximum reported total length 24.5cm (Ref. 3236).
