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: Preorbital head length not greater than head height. Barbels relatively short, with maxillary barbel not reaching beyond base of pectoral fin spine; external mandibular barbel normally not reaching beyond tip of pectoral fin spine. Barbel lengths of some juveniles (e.g. one P. monkei paratype) can slightly exceed this general condition. Pectoral fin spine serrated on both margins. Caudal peduncle high, with minimal height of peduncle usually twice as great as horizontal distance between adipose fin and caudal fin bases, or sometimes even greater. Colouration: Overall coloration light brown to greyish brown with five or six (exceptionally four or seven) dark vertical bands on flanks, that sometimes appear to consist of very large, merging spots. Small spots may be present between these bands, as well as on head and fins. As in most Parauchenoglanis species, the degree of pigmentation may vary between individual specimens. Habitat: This species is present from the Ouémé River in Benin to the Sanaga River in Cameroon. It is never found far inland (maximal distance from coast approximately 120 km). A Lower Guinea endemic, only known from the Nyong basin in southern Cameroon. Aquarium Care: At present (2022) there is no known record of any importations. Remarks: Parauchenoglanis longiceps is classed as endangered on the IUCN red list (2010). The species is only known from two localities on the Nyong River. It is threatened by logging in the area of the Upper Nyong River. Both the EOO and AOO qualify for the Endangered status.
