This genera, which includes another 8 species are quite difficult to identify, and on top of this juveniles can have different markings and colouration to the adult versions. First transferred into Parauchenoglanis by Skelton in 1993. Description: Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 0. Diagnosis: occipital process reaching to first nuchal plate; mouth equal to snout length; width of premaxillary tooth plate 15% of head length; eye large (14.2% of head length); pelvic fin short; Colouration: The coloration of the holotype of P. buettikoferi was described by Popta (1913) when it had already been preserved in alcohol for some time. She described the colour as violet brown. Afterwards the specimen was stained for bone, such that it is now impossible to perceive many details of the colour pattern. An examination of the specimen reveals the apparent presence of about four large spots on the flank. Habitat: The holotype of Parauchenoglanis buettikoferi was collected in the Warri River in the Western Niger Delta (Nigeria). No other specimens seem to have been subsequently collected. Aquarium Care: At present (2022) there is no known record of any importations. Remarks: Parauchenoglanis buettikoferi is classed as critacally endangered on the IUCN red list (2019). It is known only from the type locality, with an area of occupancy (AOO) of 4 km2. It is threatened by oil exploration and urban and industrial development, which are causing declines in habitat area and quality.
