Etymology: brachyrhabdotos: The species name brachyrhabdotos is derived from the Greek Βραχύς [= brachys], meaning short, and the Greek ραβδωτός [= rhabdotos], meaning striped, and refers to the short length of predorsal bars on the flanks, which are thin, covering between 1-2 scales, and located above the lateral line; an adjective, indeclinable (Ref. 122357).

Diagnosis: Within the Congo basin, Raiamas brachyrhabdotos can be distinguished from R. batesii, R. kheeli and R. moorii by a lower number of lateral line scales, 44-46 vs. 68-70, 65-68 and 54-61 respectively; from R. longirostris by a shorter upper-jaw length, 46-52% of head length vs. 59%, and longer pre-anal length, 67.6-69.8% of standard length vs. 73.0%; from R. buchholzi and R. christyi by the absence of a large dark spot at the base of the caudal fin vs. presence, a longer dorsal-fin base, 13.3-14.7% of standard length vs. 10.1-12.0% and 10.4-11.6% respectively, and a longer anal-fin length, 18.4-22.5% of standard length vs. 15.2-17.6% and 13.8-16.5% respectively; from R. salmolucius by a shorter head, 28.5-29.5% of standard length vs. 30.2-33.6%, and a shorter pre-anal length, 67.6-69.1% of standard length vs. 69.9-72.9%; and from R. marqueti by a greater body depth, 23.6-29.8% of standard length vs. 18.8-23.3%, a convex predorsal profile vs. more or less horizontal; furthermore, it can be distinguished from R. marqueti and R. salmolucius by short and thin predorsal bars, not extending below the lateral line and usually covering 1-2 rows of lateral line scales, vs. wide and long bars, extending below the lateral line and covering more than 2 rows of the lateral line scales; from R. intermedius by a longer predorsal length, 59.9-61.7% of standard length vs. 57.2-59.2%, and deeper head, 56-60% of head length vs. 46-56% (Ref. 122357). Outside the Congo basin, Raiamas brachyrhabdotos is distinguished from all other species, except R. ansorgii, R. nigeriensis and R. senegalensis by an intermediate number of lateral line scales, 44-46 vs. 36-38 in R. levequei, 58-63 in R. scarciensis and 39-42 in R. steindachneri; from R. ansorgii by the dorsal fin inserted slightly behind the insertion of pelvic-fin origin, i.e. about two or three lateral line scales between the verticals through the anterior base of dorsal fin and the pelvic-fin insertion vs. dorsal fin inserted well behind pectoral-fin origin, i.e. by about six lateral line scales, and the fourth infraorbital extends markedly backwards when compared to the posterior border of the third infraorbital vs. slightly behind; from R. nigeriensis by a longer head, 28.5-29.5% of standard length vs. 18.6-25.0%; and from R. senegalensis by a higher number of branched dorsal-fin rays, 9 vs. 8 (Ref. 122357).
Body shape (shape guide): elongated.
