species in Central Africa by the following combination of characteristics. Very small mouth (5.2 ≤ HL/MW ≤ 6.1). Eight to 11 teeth in the lower jaw. Upper jaw with 18–22 teeth. Eye large (2.8 ≤ HL/ED ≤ 3.2). Snout short (6.5 ≤ HL/SNL ≤ 10.7). Dorsal fin with 24–26 branched rays. Anal fin with 30–33 branched rays. Pigmentation pattern consists of two melanin markings (black patches): (1) a distinct, although generally weak, round black mark on each side of the body below the anterior base of the dorsal fin (first to fifth rays); and (2) a crescentlike mark at the base of the caudal fin on each side, not extending onto the rayed portions of the upper and lower caudal fin lobes. EOD of normal polarity.

The numerous Knollenorgan electroreceptors on the head are clearly organized into two visible rosettes (Augenrosette and Nackenrosette). In our examination of specimens, we were uncertain about the definitive presence of the third rosette, the Kehlrosette, as this structure did not appear to us to be as distinct as it is in other species (e.g.,

A). Body mostly white-silver. Dorsum slightly darker than the rest of the body. Pigmentation pattern consists of two melanin markings: (1) a distinct, but weak, round black mark below the anterior base of the dorsal fin (first to fifth rays); and (2) a crescent-shaped mark at the base of the caudal fin, which does not extend onto the rayed portions of the upper and lower caudal fin lobes. No black mark is present at the base of pectoral fins. The fins themselves are translucent.
