Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335); acanthoperca: The specific name is a Latinized combination of the Greek 'acantha', meaning a thorn, and the Latin 'opercul', meaning a cover or lid, alluding to the distinctive opercular spines developed by mature males in this species (Ref. 56332).

Morphology | Morphometrics
soft rays: 8;
Vertebrae: 35. Diagnosis: Synodontis acanthoperca is a relatively small species, with a maximum standard length below 50 mm. It is distinguished from all congeners by a distinctive pattern that includes a pair of dark patches on the caudal fin; one patch is present in the middle of each lobe of the caudal fin. Further distinguished by the presence of a well-developed opercular spine in sexually mature males (Ref. 56332).
Africa: Ogowe River in Gabon.
