Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335).
Environment / Climate / Range
Freshwater; benthopelagic. Tropical, preferred ?
Africa: known only from the Konkouré in Guinea (Ref. 7362, 57223).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 17.6 cm SL male/unsexed; (Ref. 57223)
Morphology | Morphometrics
spines: 0. Diagnosis: gill slits extending downwards beyond pectoral-fin insertions, but remaining separate by an interval greater than eye diameter; maxillary barbels longer than head, lacking ramifications, tubercles and a distinct basilar membrane; outer and inner mandibular barbels neither membranous nor globose, short and with thin ramifications; mandibular teeth mobile and short, numbering 68 in the holotype; humeral process scarcely keeled ventrally; adipose fin rather low and distinctly separate from rayed dorsal fin (Ref. 57223).
Coloration: the only known specimen, preserved in alcohol, has a blackish-brown back and a yellowish belly; no spots or marbling; all barbels dark and all fins, including adipose, black (Ref. 57223).
Oviparous (Ref. 205). Maximum total length 227mm (Ref. 57223).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.9 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (25 of 100) .
