Anal fin with at least 30 branched rays (range = 30–33). Sixteen teeth or fewer (range = 8–16) in the upper jaw, 24 teeth or fewer (range = 19–24) in the lower jaw. Eye relatively large (HL/ED ≤ 4.0, range = 3.5–4.0). Mouth sub-terminal; ratio of head length to mouth position (HL/MP) between 3.9 and 6.1. Unique pigmentation pattern with the presence of three well defined black patches: (1) a distinct (although sometimes covering only few scales), more or less round/oval, black mark situated slightly anterior to the dorsal fin on each side of the body; (2) a black mark at the base of each pectoral fin; (3) an ovoid black mark centered at the base of the caudal fin that does not extend onto the upper and lower fleshy lobes of this fin. EOD of normal polarity (i.e., first major phase head-positive).

A). Body uniformly white-silver, with the presence of three characteristic melanin marks on each side of the body: (1) a distinct, approximately round/oval black mark situated slightly anterior to the dorsal fin, sometimes covering only a few scales; (2) a black spot at the base of the pectoral fin; (3) an ovoid black mark centered at the base of the caudal fin that does not extend onto the upper and lower parts of the caudal fin. Fins translucent.

Exact type localities are unknown for P. b a l a y i and P. sauvagii. Based on our understanding of the chronology of Central African exploration at the time of the descriptions, we estimate these type localities to be the following: the vicinity of Pool Malebo on the Lower Congo River near the modern cities of Brazzaville and Kinshasa [4.25 ° S, 15.29 ° E] for P. sauvagii; and the vicinity of the present-day city Lambaréné on the Lower Ogooué River [0.7 ° S, 10.22 ° E] for P. b a l a y i.
