Etymology: Mastacembelus: Greek, mastax, -agos = bite + Greek, emballo = to throw oneself (Ref. 45335); robertsi: Named for Tyson R. Roberts who collected part of the typematerial and who first suggested that this species might well be new to science (Ref. 28147).

Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng) : 22 - 26; Các vây lưng mềm (tổng cộng) : 66 - 92; Tia cứng vây hậu môn: 1 - 2; Tia mềm vây hậu môn: 63 - 92; Động vật có xương sống: 74 - 82. Can be distinguished from other African mastacembelid species by following combination of characters: small eyes, anterior border of first dorsal spine situated before, above, or just behind posterior edge of pectoral fin; generally the color pattern is uniform (Ref. 28147).
Collected mostly from the rapids. For specimens of the Lower Congo River basin (mainstream), water temperature was recorded at a range of 24.7-29.0°C, air temperature at 23.3-30.0°C, D.O. 8.0 mg/l, and pH 7.0-7.5 (Ref. 28147).
