Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335); abditus: The specific name is the Latin adjective abditus, -a, -um, which means hidden, refers to its hitherto 'hidden' existence, being both, similar to and misidentified as Synodontis haugi in the past, and hence hidden in collections for over 20 years (Ref. 126042).

Short description
आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण): 1; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 7; गुदा कांटा 3; ऐनल सौफट रेज़: 8 - 9. Diagnosis: Synodontis abditus can be distinguished from all its congeners of the Lower Guinea ichthyological province by the following unique combination of characters: no serrations on anterior surface of the dorsal spine, vs. entirely serrated in S. albolineatus, S. batesii and S. woleuensis; a relatively high number of mandibular teeth, 63-76 vs. lower, 12-39 in S. acanthoperca, S. carineae, S. marmoratus, S. ngouniensis, S. obesus, S. punu, S. rebeli, S. robbianus, S. schall, S. steindachneri and S. tessmanni; and a relatively high number of serrations on posterior side of the pectoral spine, 16-28 for specimens of 72.2-152.7 mm standard length, vs. 16-31 in S. haugi and S. polyodon, with positive allometry (Ref. 126042).
Collected in slow-flowing parts of the river, such as the vicinity of sandy islands, the mouth of small aflluent creeks, or the edge of the main river; and where sublittoral sandstone is the predominant substrate type (Ref. 126042).
