of the Lékoli River system of Odzala National Park, Republic of the Congo. A. Photograph of a live specimen (no scale). B. Photograph of a preserved specimen (scale bar = 1.0 cm). C. EOD waveforms. One EOD was arbitrarily selected from each of two recorded individuals, and they were superimposed together. Both EODs are scaled to the same peak-to-peak voltage, and they are plotted (head-positive up) on the same time scale as an overlay centered on the largest positive peak (scale bar = 0.2 msec).

species in Central Africa by the following combination of characteristics. Dorsal fin with 22–24 branched rays. Anal fin with 25–29 branched rays. Eye large (HL/ED ≤ 4.2, range = 3.1–4.2). Mouth small (HL/MW ≥ 2.9, range = 2.9– 5.5, but see remarks). Nine to 13 teeth in the upper jaw, 17–22 teeth in the lower jaw. Melanin patterning consisting of two characteristic black patches: (1) a distinct round mark below the anterior base (first to the fifth rays) of the dorsal fin; and (2) a somewhat diffuse crescent-like mark, centered at the base of the caudal fin and extending onto the fleshy dorsal and ventral lobes of this fin. In the small number of individuals recorded so far, the EOD is of normal polarity, with four phases and a relatively slow initial rise.
