Description:
Dorsal spines (total): 1. Diagnosis: 50-59 mandibular
teeth; head width 86.2-91.5% HL; postocular length
at least 60% of snout length; maxillary barbel reaching
beyond base of pectoral spine and as long as or only
slightly shorter than head; entire margin of opercle
smooth; caudal fin without single dark patch at base
of each fin lobe; dorsal spine not serrated along
entire anterior edge. Body shape (shape guide): fusiform
/ normal. This species was described by Pellegrin
from only one specimen and is said to be identical
to S. polydon from the same catchment area
of the Ogowe drainage. They may be one and the same
species and the only difference is the teeth count,
S.polydon 75; S.haugi 85. Colouration:
The body of the fish is a uniform brown or brown with
indistinct darker spots on the body and fins. Juveniles
may also display large dark brown spots on the sides.
Etymology: The specific name "huagi"
is a tribute to the original collector of the species.
