Relevant Information:

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. Diagnosis: caudal peduncle relatively long, with minimal depth as large as horizontal distance between adipose and caudal fin bases, or slightly larger (never twice as large). Pectoral spine only partially and slightly, or not at all, serrated on its anterior margin; preorbital head length less than maximum head depth. Adipose fin height 3-7% SL, dorsal fin height 15-25% (28%) SL; head depth 56-88% head width. Barbels long, e.g. external mandibular barbel minimally 1.3 times HL, reaching to beyond tip of pectoral fin spine, maxillary barbel always reaching base of pectoral fin spine or even further. Colouration: Overall coloration purplish brown, with head as dark as, or slightly darker than, rest of body. Head and body, as well as adipose, dorsal and caudal fins speckled with numerous small dark dots, those on flank sometimes organized in rows. All other fins uniformly brown. Belly pale and nearly without dots. Habitat: The syntypes of Parauchenoglanis ahli were collected in the upper Cross River basin (West Cameroon). Aquarium Care: At present (2022) there is no known record of any importations.
