Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng) : 1; Các vây lưng mềm (tổng cộng) : 7. Distinguished from other species in this genus in having the following set of characters: 1-4 weakly developed serrations, distally located on the anterior part of the dorsal spine (vs. entirely well serrated); mandibular teeth 12-19 (vs. at least 23); membrane broad; i.e., proximally at least as brad as barbel thread, on the proximal 2/3 of the maxillary barbel (vs. none or very weakly developed); striking color pattern, black background with whitish irregularly shaped lines and dots (Ref. 78701).
Specimens have been caught in the Dola River (Gabon) at depth of 0.80 m above a sand/gravel substrate; water here was opaque, alkaline (pH 8.41) with high conductivity and with temperature of 24.0°C (Ref. 78701).
