Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335); carineae: Species named after Carine Plancke, anthropologist who worked with the Punu people in the Nyanga area, Congo Republic, in 2005-2007, and who especially likes the colour yellow; in this way the species name indirectly refers to the vivid yellow shine typical for the life colour pattern of the new species (Ref. 86529).

Dorsale stekels (totaal) : 2; Dorsale zachte stralen (totaal) : 6 - 8; Anale stekels: 0; Anale zachte stralen: 10 - 13. Diagnosis: Synodontis carineae is distinguished from all its congeners by the following unique combination of characters: entire anterior edge of dorsal spine not serrated, vs. entire anterior edge of dorsal spine serrated in S. batesii and S. albolineata; posterior margin of opercula without an opercular spine and caudal fin without two black patches, vs. generally with an opercular spine and two black patches, one on the upper and one on the lower lobe of the caudal fin in S. acanthoperca and S. punu; 18-24 mandibular teeth, vs. 50-59 in S. haugi and 85-90 in S. polyodon; maxillary barbels bordered with a well-developed, broad membrane at least as broad as barbel thread, vs. bordered with a very narrow or without membrane in S. marmorata and S. schall; snout relatively long, postocular length short, 44-58% snout length, vs. snout short, postocular length 80-107% snout length in S. nigrita, 67-76 in S. ngouniensis, 82-93 in S. robbianus, and 72-105 in S. steindachneri; dorsal spine relatively short, 16.6-23.5% of standard length, vs. dorsal spine relatively long, 27.5-32.1% of standard length in S. tessmanni, almost isometric or slightly negative allometric; head relatively narrow, width 60.1-68.5% of head length, vs. head relatively wide, width 80.5-96.2% of head length in S. obesus/rebeli-complex; 75.7-83.7 in S. violacea (Ref. 86529).
