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 colouration 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. Etymology:
The genus name Parauchenoglanis:
para-, near, referring to similarity and/or close
relationship with Auchenoglanis. The
specific name longiceps:
longus, long; ceps, head, referring to longer, narrower
head compared to P. balayi.
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.
